An overview of available HiPAP® assemblies, see table on page 127. Hull units A HiPAP® hull unit is a retractable hull unit system comprising the following main parts: Hull unit systems overview - see illustration on page 14 Hoist motor and gearbox Gantry Shaft sleeve Transducer dock with service hatch Transducer shaft Gate valve including: Positioning indicator (switch) Hydraulic system for activation of gate valve (option) 16 311046/H System description Separate units: Hoist Control Unit Remote Control Unit Hoist Control Unit with Ethernet interface Topics Hoist motor short description on page 17 Gearbox short description on page 17 Gantry short description on page 18 Shaft sleeve short description on page 18 Transducer dock short description on page 18 Mounting flange short description on page 18 Transducer shaft short description on page 19 Transducer short description on page 19 Gate valve short description on page 19 Hoist Control Unit detailed description on page 20 Remote Control Unit detailed description on page 20 Hoist Control Unit with Ethernet interface on page 21 Related topics Option: Hydraulic system for activation of gate valve (option) → see separate manual delivered with the gate valve. Hoist motor and gearbox The hoist motor and gearbox are mounted on the hoist platform. This platform is at the top of the hull unit, mounted between the tops of the gantry girders. The transducer is raised and lowered by this electric motor, which has a lifting capacity of 1000 Kip. A crank handle is provided, which can be attached to one end of the motor shaft, to enable you to raise or lower the transducer manually in the event of a power failure or for maintenance purposes. 311046/H 17 HiPAP 501/451/351/101 hull units Gantry The hull unit gantry consists of two vertical, parallel steel girders, welded to a plate at their lower ends and with the hoist motor platform bolted to their upper ends. The girders support the transducer shaft when it is raised, and hold guide rails to ensure the shaft is correctly aligned. The upper and lower limit switches are mounted onto one of the girders. Shaft sleeve The shaft sleeve is located in the bottom of the hull unit gantry. The sleeve is bolted to the transducer dock, which in turn is to be bolted to the gate valve. The shaft sleeve absorbs the forces created by the water flow acting on the transducer and the transducer shaft. To prevent water leakage and to ensure smooth raising and lowering of the transducer, the shaft sleeve is fitted with Lion twin-set packing seals at its upper lower end. The space between the seals is filled with grease to lubricate the seals and provide extra watertight security. When the sleeve is sufficiently filled, a thin film of grease will be observable on the transducer shaft. Grease refilling and level checking screws are located on the shaft sleeve. ____________________________________________________________ Note It is important that the shaft sleeve is kept watertight, and that the transducer shaft raising and lowering actions are as smooth as possible. If the system is in frequent use, the shaft sleeve may be exposed to sea growth, dirt and pollution as the transducer shaft is raised. Frequent inspections, and greasing when necessary, are strongly recommended. ____________________________________________________________ Transducer dock The transducer dock consists of a steel box which holds the transducer when the shaft is in the fully raised position. One side of the transducer dock has a service hatch. If the transducer is raised and the gate valve shut, the hatch may be opened to expose the transducer for maintenance or exchange. Zinc anodes are mounted inside the transducer dock. Mounting flange The mounting flange is welded to the vessels hull, and serves as a base for the transducer raise/lower arrangement. 18 311046/H System description Note The height of the mounting flange varies according to the specific installation requirements of the vessel. The mounting flange carries the gate valve which permits onboard maintenance or replacement of the transducer. Transducer shaft The transducer shaft is a stainless steel tube which supports the transducer at its lower end. It is supported at the top by guide rails and the raise/lower drive chains within the hull unit gantry, and it moves through the shaft sleeve. The signal cable between the transducer and the transceiver unit runs up the inside of the shaft, exiting at the top through sealing glands. The transducer shaft is raised and lowered by drive chains, driven via a gearbox by the motor mounted on the hoist platform. The tension in the drive chain is adjusted using a threaded bolt mechanism. Transducer The transducer is bolted to the lower end of the transducer shaft. When the shaft is fully raised: The transducer is stored in the transducer dock. The gate valve can be closed to protect the transducer completely from the open sea environment. Gate valve The gate valve shuts off the opening in the vessel’s hull when the transducer is raised. The gate valve is supplied with a position indicator. A hydraulic system for automatic activation of the gate valve is available as an option. This hydraulic system is described in a separate document. Gate valve position indicator The purpose of the gate valve position indicator is to give a feedback-indication of the gate valve position. The feedback is done by use of switches. The gate valve position indicator is mounted directly onto the gate valve. 311046/H 19 HiPAP 501/451/351/101 hull units It consists of a slider sliding on a threaded spindle and two switches operated by the slider. Switch A - is operated when the gate valve is fully open. Note Switch B - is operated when the gate valve is fully closed. In the middle position no switch is operated. The Hoist Control Unit uses the fully open indication (switch A) only! The Hoist Control Unit will not allow the hoist motor to move the transducer shaft unless the gate valve is fully open. Figure 3 Gate valve with position indicator Hoist Control Unit The Hoist Control Unit (HCU) is a standard unit used with all types of hull units. This unit is a steel cabinet with hinged front door. The unit is designed to be mounted on a bulkhead close to the hull unit gantry. For safety reasons there must be a clear line of sight from the HCU to the hull unit. Remote Control Unit The Remote Control Unit (RCU) is a standard unit used with all types of hull units. This unit is an aluminium cabinet with removable front panel. It holds the control buttons and indicator lamps required to enable the safe operation of the hull unit from a remote location. 20 311046/H System description Refer to the figure on page 73 This unit is designed to be mounted on a bulkhead, and will usually be located in the vicinity of the system operator station. This enables the system operator to control the hull unit rising and lowering operations without being at the physical location of the hull unit. Hoist Control Unit with Ethernet interface APOS and HiPAP mk II support remote control of the Hull Unit Hoist and the Gate Valve. A new control unit for the hoist control and/or the gate valve is required. In addition this must be enabled in the HiPAP program. 311046/H 21 HiPAP 501/451/351/101 hull units 3 TECHNICAL SPECIFICATIONS This chapter gives the technical specifications of the HiPAP® hull units.

The guidelines for installation presented in this manual must be regarded as a base for detailed plans prepared by the installation yard. ____________________________________________________________ Note Detailed mechanical drawings for the installation of the hull unit must be created and provided by the yard for the specific vessel. All drawings must be approved by local maritime authorities prior to the start of the installation. ____________________________________________________________ Warning The installation instructions given in this manual must be followed. Failure to do so may render the guarantee void. ____________________________________________________________ Warning Kongsberg Maritime AS accepts no responsibility for any damage or injury to the system, ship or personnel caused by drawings, instructions and procedures not prepared by Kongsberg Maritime. ____________________________________________________________ Topics Supply conditions on page 33 Before you start on page 34 Sonar room requirements on page 34 Torque on page 36 Tools on page 36 Basic installation information on page 37 Installation procedures on page 40 Related topics 32 Cables on page 58 Drawings in the Drawing file chapter from page 171 311046/H Installation Supply conditions Equipment responsibility Upon receipt of the equipment the system owner or installation yard automatically becomes fully responsible for the equipment, unless otherwise stated in the contract. This responsibility covers the storage period before installation, the actual installation, commissioning, and the period between the completion of the commissioning and the acceptance of the equipment by the end user (normally the owner of the vessel or platform into which the equipment is to be installed). Reception, unpacking and storage. A separate chapter, Equipment handling is provided for this information - on page 140. Installation guidelines Unless otherwise stated, the installation yard is responsible for the installation of the entire HiPAP® system. In addition, the yard is responsible for providing and connecting all cables. The actual installation and cable laying must comply with the vessel’s classification rules and the recommendations given in this manual. Assistance from Kongsberg Maritime Kongsberg Maritime AS may assist during the installation if specified in the contract or requested by the installation yard or customer. Kongsberg Maritime AS may also assist with installation drawings. All such assistance is charged to the customer at the current rates. If required during a contractual test period, the yard must provide assistance necessary for the rapid and efficient completion of the work even when the work is to be performed outside normal working hours. This requirement includes assistance from subcontractors when applicable. Excessive waiting time resulting from delays caused by the yard will be charged to the yard. 311046/H 33 HiPAP 501/451/351/101 hull units Before you start Precautions and requirements Before you start the installation, you must take the following actions: Collect the required documentation and read the applicable procedures before commencing work. Collect the required tools. Normally only a standard tool set will be required. If special tools are necessary to perform a task, the procedure will list those required. Ensure that all power is switched off to the system, and remove the fuses. If power is required to perform a task, the procedure will state so. Label the on / off switches, circuit breakers and fuses with notes clearly stating that work is being carried out on the system. Sonar room requirements The sonar room should be large enough to house all the system units, with enough space to allow maintenance to be performed efficiently. The maintenance engineer should be able to have all the cabinet doors open without undue restriction to his/her movements. The room should be easily accessible, via a hatch or door. It would be advantageous if the entry was large enough to allow installation and removal of the equipment contained in the compartment without the requirement for disassembly. Lights must be permanently installed in the sonar room. A voice intercom terminal, with connections to the operator station and the bridge, is highly recommended. Ventilation The room must be connected to the vessel’s ventilation system to ensure a supply of cooling air to the units. It is recommended that the temperature should be between +5 and +40 °C, and relative humidity should not exceed 80%. The MTBF (Mean Time Between Failure) will decrease if these limits are exceeded. 34 311046/H Installation If a ventilation system is not available, install two 3” pipes from the equipment room to a suitable fresh air location on deck. The fresh air should enter the room as close to the floor as possible, and should be extracted from as high as possible. Funnels should be located below the pipes to collect any condensation which may form. To ensure the best possible ventilation, the air outlet on deck should be located four metres higher than the air inlet, and goose-necks or hats should be mounted on the tubes to prevent the ingress of rain or sea water. Bilge pump system The room must be serviced by a bilge pump system. If it is impractical to connect the room to the vessel’s bilge pump, a separate pump must be installed to drain the room in the event of water ingress. 311046/H 35 HiPAP 501/451/351/101 hull units Torques All the nuts and bolts used in the system must be tightened to their recommended torques to prevent leaks or damage to the threads. The recommended tightening torques for the various sizes of threads is as follows: Nut/bolt torques Thread size (mm) Torque (Nm) M6 7 Nm M8 17 Nm M10 33 Nm M12 57 Nm M16 140 Nm M20 273 Nm M24 472 Nm Standard tools A standard mechanical tool set will be required for: Perform the installation, removal and replacement of modules and parts described in this manual. Perform the majority of the maintenance described in this manual. A standard electrical tool set may be required to perform repairs to cables etc. In addition, the normal heavy tools designed for installation work is required. The following expendables are recommended: Isolating plastic tape Solders Wire straps in different sizes Special tools If special tools are required for a particular procedure, they will be listed at the beginning of that procedure. 36 311046/H Installation Basic installation information The installation of the hull unit and associated units includes the following: Selection of the hull unit location. Installation of the hull unit. This includes: Installation of the mounting flange at the site chosen for the hull unit. Installation of the gate valve. Mounting of the hull unit assembly (transducer dock, shaft sleeve, gantry and transducer). Mounting of the hoist motor. Mounting of the hoist control and remote control units. Control signal and power supply cabling. Hydraulic system for activation of gate valve (option) - see separate documentation delivered with the system. Test and alignment procedures. Topics Important information on page 38 Logistics on page 38 Choice of location on page 38 Installation procedures on page 40 Related topics 311046/H Cable layout and interconnections on page 54 Test and alignments procedures from page 152 Drawing in the Drawing file chapter from page 171 37 HiPAP 501/451/351/101 hull units Important information Water inlets and protruding elements that might cause turbulence around the transducer, must not be located forward of the flange. Reinforcing plates and braces must be added to the vessel where the hull unit installation might weaken the hull construction. The Hoist Control Unit must be mounted on the bulkhead in the vicinity of the hull unit. The Hoist Control Unit controls the hull unit hoisting and lowering operations locally, therefore for safety reasons it should be mounted with a free line of sight to the hull unit. Logistics Safety - Refer to the local general safety procedures. The parts of the hull unit are heavy. Use only suitable and properly certified lifting apparatus to move the units. Personnel - Trained mechanical fitters/welders and electricians. Vessel location - The vessel must be in a dry dock during the installation of the mounting flange and gate valve. The hull unit gantry can be installed while the vessel is afloat if necessary. Special tools - Certified lifting apparatus suitable for the various parts. Cutting/welding equipment. Choice of location Caution Selecting the optimum location for the hull unit is of vital importance for the overall system performance. All external noise sources (sea noise, machinery noise, air bubbles etc), and the individual performance of the ship, must be taken into consideration. The hull unit location must be selected by a skilled engineer with experience in positioning system theory and hull unit installation. The supplier will assist if required. The compartment, within which the hull unit is to be mounted, must be accessible under all conditions. Take into consideration the following: 38 311046/H Installation The access door / hatch should be large enough to allow installation and removal of the hull unit without the requirement to disassemble it. The hull unit will pass through a hole of 800 mm diameter, provided there are no obstructions either side of the hole. The compartment should also be connected to the ship’s ventilation system. In tropical regions an air dehumidifier is recommended to reduce the likelihood of problems and corrosion due to condensation. The compartment should also be supported by a central or separate bilge pump. The hull unit should be located within 1/6 to 1/3 of the ship’s length between perpendiculars (LBP), measured from the fore perpendicular (FP). Deviations from this specification should not be made without consulting the supplier. In all cases, it is imperative that the transducer array has a free view under the keel when it is in its operational position. The location must be as close to the keel as possible. The vertical distance from the lower edge of the keel to the top of the mounting flange must be discussed with the supplier. The assistance of a dockyard crane will be required to lower the hull unit into the vessel. Heater elements of approximately 1000 watts should be installed close to the bottom of the hull unit to prevent the unit icing up in cold weather. If there is any chance of damage caused by welding or other work during the installation or a maintenance period, the hull unit must be protected with heat resistant material. The installation must be approved by an appropriate classification society. When the vessel has been launched, the air must be released from the transducer dock through the air vent cock. 311046/H Air vent cock, see figure on page 131 39 HiPAP 501/451/351/101 hull units Installation procedures The installation must be carried out according to the arrangement drawings designed specifically for the vessel.

The HiPAP® 500/450/100 transducer (the complete hull unit) must be mounted on the DN 500 mounting flange. The HiPAP® 350 transducer (the complete hull unit) can be mounted on the DN 500 or a DN 350 mounting flange. ____________________________________________________________ Note The total height of the mounting flange will depend on the Note requirements for the specific installation. The standard height is DN 500 = 600 mm/DN 350 = 200 mm, though other sizes can be provided on request. Cut the mounting flange to the shortest possible length for installation. DN 500 mounting flange The DN 500 mounting flange comprises a steel cylinder, topped by a flange ring. The flange ring contains 20 equally spaced holes, each bored and tapped to receive M24 studs. The holes are on a pitch circle diameter of 620 mm, with a pitch of 18°. See drawing in the Drawing file chapter from page 171 The flange welded around the top of the cylinder enables a gate valve to be bolted onto the top. DN 350 mounting flange The DN 350 mounting flange comprises a steel cylinder, topped by a flange ring. The flange ring contains 16 equally spaced holes, each bored and tapped to receive M20 studs. The holes are on a pitch circle diameter of 460 mm, with a pitch of 22.5°. See drawing in the Drawing file chapter from page 171 The flange welded around the top of the cylinder enables a gate valve to be bolted onto the top. 311046/H 41 HiPAP 501/451/351/101 hull units Installation accuracy and tolerances It is very important for the system accuracy that the angular orientation of the hull unit is as accurate as possible; This implies that the welding of the mounting flange into the hull must be completed with the tolerances according to the following three (3) offset angles: 1 Roll angle - The upper surface of the mounting flange must be horizontal in the athwart ships direction when the ship is floating at its normal trim, tolerance ± 1°. 2 Pitch angle - The upper surface of the mounting flange must be horizontal in the fore-and-aft direction when the ship is floating at its normal trim, tolerance ± 1°. 3 Azimuth angle - No angular requirements. Logistics Safety - Refer to the general safety procedures. Note that the mounting flange is heavy. Use only properly certified lifting apparatus to move the unit. Personnel - Minimum 3 trained mechanical fitters / welders. Vessel location - The vessel must be in a dry dock during the installation of the mounting flange. Special tools - Certified lifting apparatus. Cutting and welding equipment.

Important information ____________________________________________________________ Note The mating surface of the flange unit must be protected with a wooden cover at all times till the gate valve is about to be installed. ____________________________________________________________ Warning 42 The security of the welding is critical to the safety of the vessel. Welding must only be carried out by 311046/H Installation a certified welder, and the installation must be approved by the local classification authorities. ____________________________________________________________ Installation procedure 1 Decide the location of the hull unit. 2 Cut out a hole in the vessel’s hull with a diameter large enough to accommodate the mounting flange. The exact size of the hole must be determined by the yard. 3 Orientate the mounting flange correctly, and then weld it into position. 4 Check the flange surface to ensure that it is level, undamaged and clean, and cover it for protection. 5 Brace the flange to the hull plating and the surrounding hull frames by welding on several strengthening plates. - The exact dimensions of the plates must be determined by the yard. Gate valve installation The HiPAP® 500/450/100 hull unit fits on a DN 500 gate valve. The HiPAP® 350 hull unit fits either the DN 350 or the DN 500 gate valve. As a standard, Kongsberg Maritime recommend to use a DN 500 gate valve. Details of both are given here. Location of the unit The gate valve is installed between the mounting flange and the hull unit transducer dock. Logistics Safety - Refer to the general safety procedures. Note that the gate valve is heavy. Use only properly certified lifting apparatus to move the unit. Personnel - Minimum 3 trained mechanical fitters. Vessel location - The vessel must be in a dry dock during the installation of the gate valve. Special tools - Certified lifting apparatus. 311046/H 43 HiPAP 501/451/351/101 hull units References Drawings: - DN 350 mounting flange with gate valve on page 186 - DN 500 mounting flange with gate valve on page 185 O-ring A standard delivery includes one O-ring. The O-ring is used to seal the connection between the gate valve and the mounting flange. Procedure See also the drawing on page 185 1 Ensure that: - the mounting flange has been installed correctly - the installation has been inspected - any offsets are within tolerance. - the mating surface is clean and undamaged. 2 Manoeuvre the gate valve down into the hull unit compartment, leaving about 15 mm. - Take great care not to damage the mating surfaces of the valve. - Make sure that the end switches are facing upwards. - Protect the end switches from damage. 3 Remove the protective cover from the mating surface on the mounting flange. 4 Check to ensure the mating surface of the flange is clean and undamaged. 5 Orientate the gate valve so that the wheel points in the desired direction. 6 Make sure there are no holes alongships or athwartships. See the drawing on page 185. 44 7 Wipe a thin film of silicone grease on the O-ring and place it on the mounting flange. 8 Attach the nuts and split washers while the gate valve is still suspended. 9 Check to ensure the mating surface on the valve is clean and undamaged. 311046/H Installation Lubricate the threads with anti-seize lubricant as CRC, Loctite or Molykote. 10 Lower the valve carefully onto the mounting flange while tightening the nuts. 11 Check to ensure the valve is orientated and aligned correctly. 12 Disconnect and remove the lifting apparatus. 13 Tighten the nuts to torque 472 Nm. 14 Some of the positions have very limited space as indicated on the drawing on page 185. Alternative: 15 If there is no room for split washer use Loctite 270 or similar. 16 M24 holes may be drilled to Ø26. Replace the studs with cylinder head bolt M24x100 DIN933, A4-70 ISO 3506-1 (min). 17 Fasten to a torque of 472 Nm. Gantry installation The flange at the bottom is to be mated to the gate valve flange. The mating surface of the hull unit must be protected with wooden covers at all times until the moment of installation. The hull unit is normally transported in a wooden crate. Logistics Safety - Refer to the general safety procedures. Note that the parts of the hull unit are heavy. Use only suitable and properly certified lifting apparatus to move the units. Personnel - Four trained mechanical/electrical fitters. Vessel location - The vessel must be in a dry dock during the installation of the mounting flange and gate valve. The hull unit gantry can be installed while the vessel is afloat if necessary. Special tools - Two certified lifting apparatus, each with the capacity to support the entire hull unit (approximately 1.5 tonnes depending on hull unit model). References Drawings - hull units, outline dimensions drawing, in the Drawing file chapter from page 171. 311046/H 45 HiPAP 501/451/351/101 hull units Procedure 46 1 Manoeuvre the unit into the hull unit compartment, taking care not to damage the unit. - The mating surface of the transducer dock flange must be protected at all times during the operation. 2 Raise the unit using two cranes/tackles, one of them must be attached to the top of the unit. 3 Rotate the unit to the upright position without any part touching the deck. 4 Once the entire weight of the unit is supported by the crane attached to the top of the unit, release the crane attached to the lower end. - The unit is now hanging from one crane. 5 Manoeuvre the unit over the gate valve. 6 Stop lowering when the bottom flange of the transducer dock approaches the gate valve. 7 Remove the protective cover from transducer dock and gate valve flanges, and check that the mating surfaces are clean and undamaged. 8 Wipe a film of grease - (see page 26) in its groove, and position the O-ring seal. 9 Carefully lower the gantry down onto the gate valve. - Make sure that the studs mate correctly and easily with their corresponding holes in the transducer dock flange. - Make sure that the O-ring stays in place. 10 Place the nuts and washers onto all the stud bolts (ensuring that the required washers are used). 11 Tighten all the nuts to finger tight, and then working alternately on opposite sides of the dock. 12 Tighten the nuts to a final torque - see table on page 36. 311046/H Installation ____________________________________________________________ Note The gantry will be subjected to large forces as the vessel moves through the water, and as it pitches and rolls. The gantry must therefore be supported against the vessel’s hull in two directions 90° apart, using steel braces of suitable dimensions. These braces must be BOLTED into position to allow later maintenance or possible removal of the hull unit. Refer to the drawing. ____________________________________________________________ 13 Ensure that no units or protrusions will obstruct the vertical movement of the hull unit or the transducer cables. Hoist motor mounting The hull unit is delivered with the motor dismounted. It must therefore be fitted during the installation. It is recommended to fit the motor after the hull unit has been installed in the vessel. Procedure 1 Remove the plate covering the motor shaft key-way on the gearbox. 2 Mount the motor onto the gearbox using all the bolts provided. 3 Remove the oil filler and level plugs from the gearbox, and fill the gearbox with oil type SAE 30 if necessary. 4 Cut away the plastic vent plug on the oil filler plug to allow the gearbox to “breathe”. Hull unit surface protection The hull unit must be protected against corrosion, especially those parts which are open to the sea. The HiPAP® hull unit has two zinc anodes mounted on the shaft sleeve to protect against galvanic corrosion. However, all exposed surfaces must be painted with a primer and topcoat/antifouling paint. 311046/H 47 HiPAP 501/451/351/101 hull units Caution NEVER paint transducer face, shaft or zinc anodes. Do not paint the sealing surfaces in the gate valve, this will cause leakage. ____________________________________________________________ Logistics Safety - Refer to the general safety procedures. Switch off all power to the hull unit before commencing the work. Personnel - Painter. Vessel location - The vessel must be in a dry dock if parts open to the sea are to be painted. Dry parts within the vessel’s hull can be painted at any time. Special tools - Painting tools and primer, undercoat, topcoat, anti-fouling paint as for remainder of vessel’s hull. Hoist Control Unit installation This section describes the installation of the Hoist Control Unit (HCU). Internal layout The Hoist Control Unit (HCU) contains the electronic circuitry and relays required to raise and lower the hull unit. A rotary control switch (S1) within the cabinet enables the operator/maintenance engineer to raise or lower the hull unit locally. An additional position on the switch changes control of the hull unit to a remote control unit, usually located in the vicinity of the system’s display monitor. The switch will normally be set to this “Remote position to enable the hull unit to be controlled from the operator’s console. The units and components are laid out as shown below. 48 311046/H Installation NB! Link HTCB1 20 - 21 is not mounted. This to avoid damaging the transducer when lowering the hull unit. Link HTCB1 20 - 21 should only be mounted if a Gate Valve with no limit switch is mounted - see also drawing on page 192. Always check the Gate Valve is fully open before lowering the hull unit. Figure 6 Hoist Control Unit - internal layout Connections All cables to the HCU enter the unit through cable gland located in the base of the unit.

Preservation of HiPAP units This procedure helps preservation of HiPAP units during commissioning and maintenance work on board. Mounting flange After welding completion all exposed surfaces must be painted with primer and topcoat, and antifouling where appropriate. Damaged paint must be repaired. The mating surface of the flange unit must be protected with a wooden cover at all times till the gate valve is about to be installed. 56 311046/H Installation Gate valve Keep the gate valve in its transport protection until the start of installation. The mating surface of the gate valve must be protected with a wooden cover at all times till the gantry is about to be installed. Make sure the limit switches are protected from mechanical damage as well as from dirt or liquids. Gantry The mating surface against the gate valve must be protected with a wooden cover at all times till the gantry is about to be installed. Transducer cable should be strapped along the gantry until it is to be connected to the transceiver, and wrapped with the gantry in dust and heat resistant material during the building period at yard. Hoist control and transceiver cabinets Cabinets to be kept closed at all times when not operated. Cabinets to be wrapped in heat and dust resistant material during any welding, grinding, painting or cleaning work nearby. Cables All installed cables to be securely routed in trays, protected from being stepped on or damaged by falling objects or particles. 311046/H 57 HiPAP 501/451/351/101 hull units 5 CABLES This chapter provides general installation requirements for cables and explains how to perform the interconnections between those units. Note All cable connections must be made in accordance with the guidelines laid down by the vessel’s classification society. If no such guidelines exist, Kongsberg Maritime recommends that the Det Norske Veritas (DNV) Report No. 80-P008, “Guidelines for Installation and Proposal for Test of Equipment” be used as a guide. See Cable plan and interconnections document 325840 (separate document) for more information. Topics Cable gland assembly procedure on page 59 Basic cable requirements on page 61 Cable plan on page 64 Transducer to transceiver unit cables installation on page 66 Related topics 58 Cable plan and interconnections on page 200 Drawings in the Drawing file chapter from page 171 311046/H Cables Cable gland assembly procedure Cable glands are used whenever a cable passes through a watertight bulkhead or into a cabinet, to seal the opening through which the cable passes and to protect the cable from abrasion on the edges of the hole. Follow the guidelines in this chapter when installing cables through cable glands. ____________________________________________________________ Note There are many different types of cable gland on the market. This procedure describes the types used (now and previously) as standard in the units manufactured by Kongsberg Maritime. The cable glands are not supplied with the system. ____________________________________________________________ Even though the cabinets from Kongsberg Maritime may be prepared for specific types, the installation yard will be responsible for selecting cable gland types and installing them. General procedure 1 Ensure all the cables to be connected are completely isolated from any power sources. - This is done by: Switch off and remove the supply fuses from any units or systems into which the cables are already connected. 2 Select the cable to be connected into the cabinet, and select the cable gland through which the cable is to pass. ____________________________________________________________ Note A minimum of 5 cm (recommended 5 - 10 cm) of slack cable must be allowed, both inside and outside the cabinet, when installing cables. This is to allow for vibration damping, maintenance and measurement errors. Always double-check your measurements before taking any irreversible actions. ____________________________________________________________ 3 Depending on whether the cable has already been installed in conduits, either a (installed) measure the maximum length of cable required to reach from the final cable clip outside the cabinet to the terminal blocks inside the cabinet, add 20 cm, then remove the excess cable, or: b (loose cable) measure the maximum length of wire required to reach from the cable gland to the terminal 311046/H 59 HiPAP 501/451/351/101 hull units blocks inside the cabinet, add 20 cm. and mark the cable. ____________________________________________________________ Note The cable’s outer insulation will extend into the cable gland to a point approximately 5 mm outside the outer surface of the cabinet wall into which the cable gland is secured. ____________________________________________________________ 4 Take care not to damage the screening. Carefully remove the outer insulation from the required cable length. 5 Leave an appropriate length of the screen exposed from the insulation, and cut off the remainder. Securing and terminating the cables 60 1 Refer to the wiring diagram and ensure that there is 5 to 10 cm slack cable inside the cabinet, - then prepare and connect the cable cores to the appropriate terminals within the cabinet. 2 Secure the cable within the cabinet using cable clips. 3 Check the terminal connections against the wiring diagram to ensure they are correct. 311046/H Cables Follow the same procedure for all the cables and cable glands. Once all the cables have been fitted: 4 Check the cabinet to ensure all tools and rubbish are removed, before you close the cabinet door. Once all the cables have been fitted and checked: Caution Caution Take the appropriate safety measures, then replace the fuses and apply power to the system. Perform a system test to ensure the installation has been conducted successfully. Basic cabling requirements Cable trays All permanently installed cables associated with the system must be supported and protected along their entire lengths using conduits and/or cable trays. The only exception to this rule is over the final short distance (max. 0.5 m) as the cables run into the cabinets/units to which they are connected. These short service loops are to allow the cabinets to move on their shock mounts, and to allow maintenance and repair. Wherever possible, cable trays must be straight, accessible and placed so as to avoid possible contamination by condensation and dripping liquids (oil, etc.). They must be installed away from sources of heat, and must be protected against physical damage. Suitable shields must be provided where cables are installed in the vicinity of heat sources. Unless it is absolutely unavoidable, cables should not be installed across the vessel’s expansion joints. If the situation is unavoidable, a loop of cable having a length proportional to the possible expansion of the joint must be provided. The minimum internal radius of the loop must be at least twelve times the external diameter of the cable. Where a service requires duplicate supply lines, the cables must follow separate paths through the vessel whenever possible. Signal cables must not be installed in the same cable tray or conduit as high-power cables. Cables containing insulation materials with different maximum-rated conductor temperatures should not be bunched together (that is, in a common clip, gland, conduit 311046/H 61 HiPAP 501/451/351/101 hull units or duct). When this is impractical, the cables must be carefully arranged such that the maximum temperature expected in any cable in the group is within the specifications of the lowest-rated cable. Cables with protective coverings which may damage other cables should not be grouped with other cables. Cables having a copper sheath or braiding must be installed in such a way that galvanic corrosion by contact with other metals is prevented. To allow for future expansion of the system, all cables should be allocated spare conductor pairs. Also, space within the vessel should be set aside for the installation of extra cables. Radio Frequency interference All cables that are to be permanently installed within 9 m (30 ft) of any source of Radio Frequency (RF) interference such as a transmitter aerial system or radio transmitters, must, unless shielded by a metal deck or bulkhead, be adequately screened by sheathing, braiding or other suitable material. In such a situation flexible cables should be screened wherever possible. It is important that cables, other than those supplying services to the equipment installed in a radio room, are not installed through a radio room, high power switch gear or other potential sources of interference. Cables which must pass through a radio room must be screened by a continuous metal conduit or trunking which must be bonded to the screening of the radio room at its points of entry and exit. Physical protection Cables exposed to the risk of physical damage must be enclosed in a steel conduit or protected by a metal casing unless the cable’s covering (e.g. armour or sheath) is sufficient to protect it from the damage risk. Cables exposed to an exceptional risk of mechanical damage (for example in holds, storage-spaces and cargo-spaces) must be protected by a suitable casing or conduit, even when armoured, if the cable covering does not guarantee sufficient protection for the cables. Metallic materials used for the physical protection of cables must be suitably protected against corrosion. 62 311046/H Cables Grounding Grounding connections should be made using a conductor which has a cross-sectional area appropriate for the current rating of the cable, or with a metal clamp which grips the metallic covering of the cable and is bonded to the hull of the vessel. These cable coverings may also be grounded by means of glands specially intended for this purpose and designed to ensure a good ground connection. The glands used must be firmly attached to, and in good electrical contact with, a metal structure grounded in accordance with these recommendations. Electrical continuity must be ensured along the entire length of all cable coverings, particularly at joints and splices. In no case should the shielding of cables be used as the only means of grounding cables or units. Metallic casings, pipes and conduits must be grounded, and when fitted with joints these must be mechanically and electrically grounded locally. Cable connections All cable connections are shown on the applicable cable plan and interconnection diagrams. Where the cable plan shows cable connections outside an equipment box outline, the connections are to be made to a plug or socket which matches the plug or socket on that particular item of equipment. Where two cables are connected in series via a junction box or terminal block, the screens of both cables must be connected together but not grounded. Cable terminations Care must be taken to ensure that the correct terminations are used for all cable conductors, especially those that are to be connected to terminal blocks. In this case, crimped sleeveterminations must be fitted to prevent the conductor core from fraying and making a bad connection with the terminal block. It is also of the utmost importance that where crimped terminations are used, the correct size of crimp and crimping tool are used. In addition, each cable conductor must have a minimum of 15 cm slack (service loop) left before its termination is fitted. 311046/H 63 HiPAP 501/451/351/101 hull units Cable identification Cable identification codes corresponding to the cable number shown in the cable plan must be attached to each of the external cables. These identification codes should be positioned on the cable in such a way that they are readily visible after all panels have been fitted. In addition, each cable conductor should be marked with the terminal board number or socket to which it is connected. Cable planning All cables must be available at the units, properly installed in cable ducting. ____________________________________________________________ Caution All power must be switched off to the system prior to the cable installation. ____________________________________________________________ Caution Do not to exceed the physical limitations of the cables. ____________________________________________________________ Note Special system requirements, adaptions or components may introduce special drawings and cables. ____________________________________________________________ Note In order to meet the EMC requirements, dedicated grounding cables have been used to connect the various system units to the vessel’s ground. These cables are identified as “X” on the cable plan drawings. The braided grounding cable required is supplied with the system. These cables must not be longer than 1 metre. ____________________________________________________________ The cabling for all HiPAP® systems are in principle the same, and most of the cables are identical. The only system specific cable is: Transducer cable from the transceiver unit to the transducer. All cables used are specified in the following sections. Cable specifications Each individual cable is identified on the cable plans. The cables fall into two categories: Cables provided by the installation yard. System cables supplied with the delivery. 64 311046/H Cables Yard cables The cables to be provided by the yard are identified as such in the cable listing. ____________________________________________________________ Note The cable specifications given are the minimum specifications. ____________________________________________________________ For each cable the following is provided: Connection to be made on each end of the cable (including system units, terminal block identification and plug/socket to be used). Number of cores. Recommended cable type. Minimum cable specifications. ____________________________________________________________ Caution Any special requirements must be considered in addition to those listed. Kongsberg Maritime accepts no responsibility for damage to the system or reduced operational performance if this is caused by improper cabling. ____________________________________________________________ System cables Several cables will be supplied with the system. Such cables normally consist of power cables for peripheral equipment, and interconnection cables for computers and/or operator stations. These cables are normally delivered (packed) with the units. Cable connections All cables must be terminated correctly. The required information is provided in the applicable interconnection drawings. Special cables Special system applications or requirements may result in additional or modified cable runs. 311046/H 65 HiPAP 501/451/351/101 hull units Transducer to transceiver unit cables installation Topics Cable information on page 66 HiPAP® 501/451 (x81) on page 67 HiPAP® 351/101 (x81) on page 67 HiPAP® 351/101 (x21) on page 67 Model x81 - transducer cable connection on page 68 Model x21 - transducer cable connection on page 68 Cables between the hull unit and the Hoist Control Unit on page 68 Cable information Cabling from transducer to transceiver is separated in 2 parts.

The operation is the same for all types of HiPAP® hull units. ____________________________________________________________ Caution Once the transducer is lowered, the depth of water under the vessel must be monitored closely. Max vessel speed - when the transducer is in the lowered position, refer to information on page 23. ____________________________________________________________ Warning Important information about remote control operation – see page 70. ____________________________________________________________ Topics Hoist control operation on page 70 Remote control operation on page 72 Hoist control operation from Operator Station/APOS on page 74 Manual operation of the hoist motor on page 74 Gate valve operation on page 80 Related topics Electrical system principles on page 137 Hoist control operation The hull unit will normally be controlled from the operator’s position using the Remote Control Unit (RCU). Important remote control information ____________________________________________________________ Warning 70 When the system is under remote control the hull unit will move without warning, so ensure; - Personnel and equipment are kept well clear - The gate valve is open. - Check that the link HTCB1 20 – 21 is not mounted in the Hoist Control Unit. This to avoid damaging the transducer when lowering the hull unit. 311046/H Operation Link HTCB1 20 – 21 should only be mounted if the gate valve with no limit switch is mounted - see also drawing on page 192. Always set the rotary switch S1 to STOP before approaching the hull unit. ____________________________________________________________ If the hull unit must be raised or lowered for maintenance purposes, the HCU must be used. The HCU is in the vicinity of the hull unit and the maintenance engineer must have a clear view of the hull unit while it is being raised or lowered. The engineer will then be in a much better position to start and stop the unit as required. The HCU incorporates a rotary switch, S1, which is used to raise or lower the hull unit locally. Figure 10 Hoist Control Unit - switch S1 Before you start lowering/raising the hull unit, check to ensure that: 1 No maintenance work is being performed on the hull unit. 2 There are no obstructions around the hull unit which could prevent it from moving (or jam it while it is moving). Lowering the hull unit 311046/H 1 Ensure that the gate valve is open. 2 Open the HCU door. 71 HiPAP 501/451/351/101 hull units 3 Set rotary switch S1 to LOWER. 4 Once the hull unit has reached the required position, set the switch S1 to STOP. The hull unit will stop automatically when it reaches its fully lowered position. Once it has stopped, set the switch to STOP to prevent the unit from moving in the event of a fault. 5 Close the HCU door. Raising the hull unit 1 Open the HCU door. 2 Set rotary switch S1 to HOIST. 3 Once the hull unit has reached the required position, set the switch S1 to STOP. The hull unit will stop automatically when it reaches its fully raised position. Once it has stopped, set the switch to STOP to prevent the unit from moving in the event of a fault. 4 Close the HCU door. 5 If the hull unit is to be left in fully raised position for some time, you are advised to close the gate valve. Stopping the hull unit If the hull unit must be stopped at any position other than fully raised or fully lowered, set the rotary switch to STOP at the appropriate time. Always set the switch to STOP before commencing maintenance work on the hull unit. Remote operation of the hull unit Once you have completed all operations requiring local control of the hull unit, ensure all personnel, tools etc. are clear of the hull unit and set the rotary switch S1 to REMOTE. The hull unit is then controlled by the RCU located in the vicinity of the operator station. Remote control operation The operator uses the control buttons on the RCU to raise and lower the hull unit from the vicinity of the operator station. 72 311046/H Operation The RCU holds the following three control buttons (with indicator lamps): RAISE / UP STOP LOWER / DOWN The unit also holds a dimmer potentiometer for adjusting the light intensity. Figure 11 Remote Control Unit Control buttons The control buttons have the following functions: 311046/H RAISE/UP This control button initiates the transducer raising function. STOP This control will stop all movement of the hull unit. It can be activated at any time. To continue the operation, you must press the RAISE / UP button or the LOWER / DOWN button. LOWER / DOWN This control initiates the transducer lowering function. 73 HiPAP 501/451/351/101 hull units Indicator lamps The indicator lamps operate as follows: RAISE / UP This lamp will be lit when the hull unit is in the fully raised position. STOP This lamp will be lit whenever the hull unit is stationary. LOWER /DOWN This lamp will be lit when the hull unit in the fully lowered position. ____________________________________________________________ Note The STOP button can be pressed at any time to stop the unit. ____________________________________________________________ Note If movement of the shaft is obstructed between the raised and lowered positions, (for example you could have pressed the LOWER/DOWN button without first opening the gate valve), a motor protection relay will trip and cut off power to the hoist motor. The STOP lamp will be lit. To restart the motor, it must be reset. ____________________________________________________________ Motor reset To reset the motor, press the Reset button on the motor protection relay in the HCU. Refer to the figure on page 49 Hoist control operation from Operator Station/APOS Caution Check the water depth before lowering the transducer to avoid damaging the transducer.

With this you can raise or lower the transducer manually in the event of a power failure or for maintenance purposes. The motor has an internal brake mechanism which must be released manually, if you are to use the hand crank. ____________________________________________________________ Note Ensure that power to the hull unit is switched off before using the handle. ____________________________________________________________ Figure 13 Hand crank stowed 311046/H 79 HiPAP 501/451/351/101 hull units Procedure 1 Loosen the hand crank from the hoist platform. 2 Then put on the hand crank on the top of the motor. 3 Tighten the screw (on the top of the motor/gearbox - see figure below) until you are able to turn the motor shaft with the hand crank. Figure 14 Brake mechanism screw ____________________________________________________________ Caution After the manual operation is complete remember to: - Loosen the screw. - Remove the hand crank and put it back into storage. ____________________________________________________________ Warning For safety reasons, always keep the gate valve closed when the hull unit is in fully raised position and the break is released. ____________________________________________________________ Gate valve operation If a hydraulic system for operation of the gate valve is fitted (option), the gate valve will normally be open / closed using the remote / local unit of the hydraulic system. However, in the event that the gate valve must be closed or opened for maintenance purposes, use the manual hand wheel. 80 311046/H Maintenance 7 MAINTENANCE This chapter contains information on how to perform all normal preventive and corrective maintenance on the HiPAP® hull units system. The procedures are identical for all HiPAP® system. The technical descriptions included in this manual are intended to be used by maintenance technician and / or fitters. ____________________________________________________________ Note If your organization (or vessel) does not have the appropriate personnel available, you are strongly advised to contact either Kongsberg Maritime or your dealer for assistance. ____________________________________________________________ Warning Kongsberg Maritime accepts no responsibility for any damage or injury to the system, ship or personnel caused by drawings, instructions and procedures not prepared by Kongsberg Maritime. Neither Kongsberg Maritime nor our dealers will accept responsibility for damage or injury to the vessel, system or personnel resulting from incorrect maintenance performed on the system. ____________________________________________________________ 311046/H 81 HiPAP 501/451/351/101 hull units Topics Safety on page 82 Before you start on page 83 Maintenance philosophy on page 83 Maintenance schedule on page 84 Shaft sleeve and shaft, special attention on page 84 Watertightness test on page 85 Preventive maintenance on page 86 Corrective maintenance on page 92 Related topics Torque on page 36 Tools on page 36 Grease for shaft and chain on page 26 Gear oil on page 27 Spare parts on page 124 Drawings in the Drawing file chapter from page 171 Safety Refer to standard company/vessel safety procedures before commencing maintenance work. See also High voltage safety warning on page II in this manual. ____________________________________________________________ Note After any maintenance work, the system must be checked to ensure it works correctly. Refer to the procedure in the Test and alignment procedures chapter. ____________________________________________________________ 82 311046/H Maintenance Before you start Before you start performing any maintenance, inform the control room that you are about to carry out maintenance on the hull unit, and that the hull unit will be switched off while the maintenance is being carried out. Maintenance philosophy The maintenance philosophy recommended by Kongsberg Maritime is: On-board maintenance should be carried out by a maintenance engineer, with the assistance of the operator. The maintenance should include the following: Calibrations Simulations Functional tests Traditional troubleshooting based on a good knowledge of the system. Replacement of faulty parts should be limited to the line replaceable units (LRUs) recommended in the spare parts list. ____________________________________________________________ Note To reduce the number of spare boards required, standard circuit boards without software may be provided. In the event of a replacement becoming necessary, the software on the faulty circuit board must then be transferred to the new board. Any links and switches on the new circuit board must also be set as on the old board. ____________________________________________________________ Whenever a faulty unit has been replaced, the unserviceable unit should be sent to Kongsberg Maritime, or an appointed dealer, for repair. ____________________________________________________________ Note If maintenance work must be performed on the “wet” sections of the hull unit, always perform a watertightness test before breaking the watertight integrity of the hull unit. Refer to page 85 ____________________________________________________________ 311046/H 83 HiPAP 501/451/351/101 hull units Maintenance schedule Maintenance routines must be performed regularly and effectively to ensure that the equipment is kept in top condition. Effective maintenance is even more important with the equipment described in this manual, as a faulty unit could have disastrous consequences in the presence of an inflammable atmosphere. The chart below states the maximum recommended intervals at which the various routines should be performed - the intervals should be decreased if the system is used excessively, or if the maintenance engineer considers it necessary. Maintenance chart Routine Frequency Hull unit general inspection Annual Filling motor gearbox Annual Filling shaft sleeve Annual Cleaning transducer Annual Lubricating drive chains/sprockets 2 months Lubricating elevator screw and nut 2 months Cleaning transducer shaft 2 months Cleaning transducer Regularly Inspection of junction box 6 months Hoist Control Unit general inspection Annual Remote Control Unit general inspection Annual Gate valve OPEN/CLOSE 2 weeks Actuator Annual Shaft sleeve and shaft, special attention Special attention must be given to the shaft sleeve and transducer shaft. The sleeve contains several seals, and these will wear as the transducer is lowered and raised. It is therefore important that you: 84 311046/H Maintenance Keep the transducer shaft clean, and remove growth and dirt. Keep the transducer shaft oiled at all times. Keep the shaft sleeve filled with grease at all times. If the shaft becomes dirty or the shaft sleeve runs dry, the seals will wear faster. This will in turn lead to leaks, and the seals will then need to be replaced. Watertightness test The hull unit compartment is located in the keel of the vessel below the water-line. Maintenance on the hull unit must therefore be carried out with care to ensure that no water leaks occur. It is important to check that the gate valve below the hull unit is closed and watertight before any maintenance procedure is performed that involves breaking the watertight integrity of the hull unit. Logistics Safety - Refer to the general safety procedures. Personnel - Anyone trained in the procedure. Vessel location - Afloat. Special tools - None. Procedure The procedure is as follows: 311046/H 1 Fully raise the hull unit. 2 Switch off all power to the system. 3 Close the gate valve. 4 Check the gate valve is sealed by opening the air-vent cock on the top of the transducer dock. - A small amount of water should flow out as the pressure within the transducer dock equalises with the ambient air pressure. 5 When the water stops flowing, crack open the gate valve and close it again. - Water should start flowing out of the air-vent when the valve is cracked open, and should cease soon after it is closed again. This action will prove that the lack 85 HiPAP 501/451/351/101 hull units of water flow is because the gate valve is sealed, and not merely because the air-vent cock is blocked. Once the test has been performed satisfactorily, you can assume that it is safe to continue with the required maintenance routines. ____________________________________________________________ Caution If for any reason there is a delay between performing the watertightness test and starting the maintenance, play safe - perform the test again. ____________________________________________________________ Preventive maintenance Topics Lubrication on page 86 Hull unit inspection on page 87 Hoist Control Unit inspection on page 89 Remote Control Unit inspection on page 90 Lubrication Refer to Drive chains lubrication on page 96 Refer to Hoist motor, gear box lubrication 92 Several parts of the hull unit must be inspected to ensure the correct amounts of lubricants are present. The following points must be checked: 86 1 The gearbox - Oil level shall be to the top screw on the side of the unit. - Oil type: SAE 30 motor oil. - 1 litre of oil is needed if the gear box is empty. 2 The shaft sleeve - The transducer shaft must be covered with a thin film of grease. - Grease type: Exxon Mobil Mobile EP2 (or equivalent) - Approx. 1.5 kg of grease on shaft sleeve and chains. 3 The drive chains and sprockets - The drive chains must be lightly greased to ensure smooth operation and prevent corrosion. - Grease type: BIRAL VG/HT (or equivalent). - Approx. 1.5 kg of grease on shaft sleeve and chains. 311046/H Maintenance 4 The transducer shaft guide rails - The guide rails ensure the transducer shaft remains correctly orientated relative to the vessel at all times. These guides must be checked at regular intervals and adjusted as necessary. - Grease type: BIRAL VG/HT (or equivalent). 5 Limit switches - The limit switches are activated by rotating arms. These arms are mounted on bearings, and are fitted with wheels to reduce friction. A few drops of oil on the moving parts at regular intervals will help to keep the switches trouble-free. Hull unit inspection The hull unit must be inspected at regular intervals and if it has not been used for an extended period of time. Logistics Safety - Refer to the general safety procedures. Personnel - Trained maintenance/inspection engineer. Vessel location - Afloat. Special tools - None. Spare parts - Depending on the results of the inspection. Procedure 311046/H 1 Switch off power to the system in the Hoist Control Unit. 2 Check all power and signal cables for signs of damage or overheating. 3 Open all the junction boxes and check all cable terminations to ensure they are tight. Close the boxes firmly on completion. 4 Check all cable glands to ensure they seal correctly. - Refer to the Cable gland assembly procedure in the Cable layout and interconnections section if a gland is found to be loose. 5 Check around the hull unit, especially around the mounting flange for signs of water leakage. - If water is detected, find the leak.

Refer to the hull unit raise / lower checks on page 164. System alignment One of the most important variables that will affect system accuracy is the alignment of the transducer with respect to the vessel’s fore-and-aft axis. After any maintenance procedure which could affect the alignment of the transducer (removal of the transducer, adjustment of guide rails etc.), or if the maintenance engineer suspects that the transducer has moved out of alignment, an alignment test should be conducted. This may require that the vessel goes into dry dock, so all other options should be thoroughly investigated first. The system software can then be set up to take into account any misalignments in the system. Contact Kongsberg Maritime for assistance with the alignment checks. Refer to the hull unit installation test and alignment procedure on page 152. 311046/H 123 HiPAP 501/451/351/101 hull units 8 SPARE PARTS This chapter lists the parts and modules defined by Kongsberg Maritime as Line Replaceable Units (LRUs).

The units may be supplied as spare parts, or as parts of a delivery. Topics Transportation on page 141 Re-packing on page 150 ESD precautions on page 150 Temperature protection on page 151 Transportation Unless otherwise stated in the accompanying documentation, electronic, electro-mechanical and mechanical units supplied by Kongsberg Maritime can be transported using all methods approved for delicate equipment; (by road, rail, air or sea). The units are to be transported in accordance with general or specific instructions for the appropriate unit(s), using pallets, transport cases, or carton boxes as appropriate. Note Special local restrictions concerning air transportation may be applied to units containing certain types of batteries. The units should be checked and the regulations investigated by the packer/shipper before the unit is dispatched. Local transportation All local transportation must be carried out according to the same specifications as for the initial delivery. In general, all units must be handled with care. The carton or case containing the equipment must be kept dry at all times, and must be sheltered from the weather. It must not be subjected to shocks, excessive vibration or other rough handling. The carton or case will normally be marked with text or a symbol indicating which way up it is to be placed. Follow any instructions given and ensure the case is always placed with its “top” uppermost. 311046/H 141 HiPAP 501/451/351/101 hull units The carton or case must not be used for any purpose for which it was not intended (step, table, etc.), and in the absence of other information, no other cartons or cases must be stacked on top of it. Lifting A heavy crate will normally be marked with its weight, and the weights of other cartons or crates will normally be entered on the packing list. You must always check the weight of a crate before attempting to lift it. You must always use lifting apparatus that is certified for the load. Heavy units may be equipped with lifting lugs for transportation by crane within the workshop or installation area. Before a crane is used, check: You must check the applicable weight certificate for the crane. You must check the security of the lifting lugs. Ensure that all available lifting lugs are used. Ensure the unit remains under control during the operation to avoid damage to the unit, equipment or personnel. Heavy units may be transported using a fork-lift truck. Special attention must then be paid to the position of the unit’s centre of gravity. The units must be properly secured to the truck. Storage prior to installation or use When a system, a unit or a spare part has been delivered to the customer, it may be subject to long-time storage prior to installation and use. During this storage period, certain specifications must be met. The equipment must be preserved and stored in such a way that it does not constitute any danger to health, environment or personal injury. 142 1 The equipment must be stored in its original transportation crate. 2 Ensure that the units are clearly separated in the shelves and that each unit is easily identifiable. 3 The crate must not be used for any purpose for which it was not intended (e.g. work platform etc.). 311046/H Equipment handling 4 The crates must not be placed on top of each other, unless specific markings permit this. 5 The crates must not be placed directly on a dirt-floor. 6 Do not open the crate for inspection unless special circumstances permit so. - “Special circumstances” may be suspected damage to the crate and its content, or inspections by civil authorities. - If any units are damaged, prepare an inspection report stating the condition of the unit and actions taken. Describe the damage and collect photographic evidence if possible. Re-preserve the equipment. - If the units are not damaged, check the humidity absorbing material. If required, dry or replace the bags, then repack the unit(s) according to the packing instructions. 7 If the crate has been opened, make sure that is it closed and sealed after the inspection. Use the original packing material as far as possible. Storage temperature and humidity 1 The storage room/area must be dry, with a non-condensing atmosphere. It must be free from corrosive agents. 2 The storage area’s mean temperature must not be lower than -30° C, and not warmer than +70° C. - If other limitations apply, the crates will be marked accordingly. ____________________________________________________________ Note Transducers must not be stored in temperatures below -30° C, or higher than +55° C. ____________________________________________________________ 3 The crate must not be exposed to moisture from leakages. 4 The crate must not be exposed to direct sunlight or excessive warmth from heaters. Shock and vibration 1 311046/H The crate must not be subjected to excessive shock and vibration. 143 HiPAP 501/451/351/101 hull units ESD precautions Refer to the information on page 150. Inspection An inspection must be carried out immediately after the units have arrived at their destination. Check all wooden or cardboard boxes, plastic bags and pallets for physical damage. Look for signs of dropping, immersion in water or other mishandling. If damage is detected externally, you will have to open the packaging to check the contents. Request a representative of the carrier to be present while the carton is opened, so any transportation damage can be identified. If any units are damaged, prepare an inspection report stating the condition of the unit and actions taken. Describe the damage and collect photographic evidence if possible. Send the inspection report to Kongsberg Maritime as soon as possible. If the units are not damaged, check the humidity absorbing material. If required, dry or replace the bags, then repack the unit(s) according to the packing instructions. Unpacking Normal precautions for the handling, transportation and storage of fragile electronic equipment must be undertaken. ____________________________________________________________ Note If the unit is not to be prepared for immediate use, you may consider storing it unopened in its original packing material. However, it may be useful to open the case to check its contents for damage and retrieve any accompanying documentation. ____________________________________________________________ Check the carton before opening it to ensure it shows no signs of dropping, immersion in water or other mishandling. If the carton shows signs of such damage, refer to the paragraph covering Inspection on receipt. Place the carton on a stable work bench or on the floor with the top of the carton uppermost. In the absence of other instructions, always open the top of the carton first. The contents will normally have been 144 311046/H Equipment handling lowered into the carton from above, so this will usually be the easiest route to follow. Care must be used when opening the carton to ensure the contents are not damaged. ____________________________________________________________ Caution Do not use a knife to open cardboard cartons - the contents may lie close to the surface, and may be damaged by the blade. ____________________________________________________________ If the carton has been closed using staples, remove the staples from the carton as you open it. This will reduce the possibilities of scratch injury to yourself and damage to the contents. If a wooden crate has been closed using screws, always remove them using a screw-driver. Do not attempt to prise the lid off with a crow-bar or similar. Once the carton is open, carefully remove all loose packing and insulation material. Check for manuals and other documents that may have been added to the carton during packing, and put these to one side. Check also for special tools, door keys etc. Electronic and electro-mechanical units ____________________________________________________________ Caution Beware of the dangers of Electro-Static Discharge (ESD) both to yourself and to the equipment, when handling electronic units and components. ____________________________________________________________ Electronic and electro-mechanical units will normally be wrapped in a clear plastic bag. Lift the unit, in its bag, out of the carton and place it in a stable position on the floor/work bench. 1 Inspect the unit for damage before opening the plastic bag. ____________________________________________________________ Note Cables must never be used as carrying handles or lifting points. ____________________________________________________________ Note Do not break the seal to open a circuit board package before the board is to be used. If the board package is returned to the manufacturers with the seal broken, the contents will be assumed to have been used and the customer will be billed accordingly. ____________________________________________________________ 2 311046/H Assuming all is well, open the bag and remove the unit. 145 HiPAP 501/451/351/101 hull units 3 Open the unit and check inside. Remove any packing and desiccant material that may be inside. Mechanical units Mechanical units may be heavy. 1 Using a suitably certified lifting apparatus, lift the unit out of the crate and place it in a stable position on the floor/work bench. 2 Inspect the unit for damage and remove any packing material that may be inside the unit. Transducers Transducers may be supplied mounted to a hull unit (if any), or packed separately. Crates are normally identified by the order number and the serial number. The transducer face must be protected by a rigid, padded cover (e.g. a wooden box lined with foam rubber) all the time it is exposed to the risk of physical damage. ____________________________________________________________ Note Once the units are unpacked, great care must be taken to ensure that transducers and cabling are not exposed to any mechanical stress. Never lift the transducers by the transducer cable. ____________________________________________________________ Re-packing If the unit is not to be installed immediately, re-pack it in its original packing material to prevent damage in the intervening period. Refer to the information on page 150. Storage after unpacking The equipment should be stored in its original transportation crate until ready for installation. The crate must not be used for any purpose for which it was not intended (e.g. work platform etc.). Once unpacked, the equipment must be kept in a dry, non condensing atmosphere, free from corrosive agents and isolated from sources of vibration. 146 311046/H Equipment handling ____________________________________________________________ Note Do not break the seal to open a circuit board package before the board is to be used. If the board package is returned to the manufacturers with the seal broken, the contents will be assumed to have been used and the customer will be billed accordingly. ____________________________________________________________ The unit must be installed in its intended operating position as soon as possible after unpacking. If the unit contains normal batteries, these may have been disconnected/isolated before the unit was packed. These must then be reconnected during the installation procedure. Units containing batteries are marked. ____________________________________________________________ Caution Units containing lithium or alkaline batteries must be handled separately and with care. Such units are marked accordingly. Do not attempt to recharge such batteries, open them or dispose of them by incineration. Refer to the applicable product data sheets. ____________________________________________________________ After use storage If a unit is removed from its operating location and placed into storage, it must be properly cleaned and prepared before packing. Cleaning cabinets If a cabinet has been exposed to salt atmosphere while it was in use, it must be thoroughly cleaned both internally and externally to prevent corrosion. 311046/H 147 HiPAP 501/451/351/101 hull units Wipe the cabinet externally using a damp cloth and a little detergent. Do not use excessive amounts of water as the unit may not be water tight. On completion, dry the unit thoroughly. All surfaces must be inspected for signs of corrosion, e.g. Flaking / bubbling paint, stains etc. Damaged or suspect areas must be cleaned, prepared and preserved using the correct preservation mediums for the unit. The mediums to be used will usually be defined in the units’ maintenance manual. All surfaces must be inspected for signs of corrosion, e.g. flaking/bubbling paint, stain etc. Damaged or suspect areas must be cleaned, prepared and preserved using the correct preservation mediums for the unit. Open the unit, and using a vacuum cleaner, remove all dust etc. from the unit. Great care must be taken to ensure the circuit boards and modules are not damaged in the process. Mechanical units If a mechanical unit may have been exposed to a salt atmosphere while it was in use, it must be thoroughly cleaned both internally and externally to prevent corrosion. If the construction materials and type of unit permits, wash the unit using a high-pressure hose and copious amounts of fresh water. Examples: The lower parts of hull units (outside the hull) Subsea units 148 311046/H Equipment handling Ensure that all traces of mud and marine growth are removed. Use a wooden or plastic scraper to remove persistent growth, barnacles etc. On completion, dry the unit thoroughly. ____________________________________________________________ Caution Do not use a high pressure hose in the vicinity of cables or transducers. Do not use sharp or metal tools on a transducer face. ____________________________________________________________ If the materials or type of unit prevents the use of a highpressure hose, wipe the unit using a cloth dampened with water containing a little detergent. Examples: The upper parts of hull units (inside the hull) Hydraulic systems Do not use excessive amounts of water as some components on the unit may not be water tight. Wipe off the detergent with a damp cloth, and then dry the unit thoroughly. All surfaces must be inspected for signs of corrosion, e.g. flaking/bubbling paint, stain etc. Damaged or suspect areas must be cleaned, prepared and preserved using the correct preservation mediums. The mediums to be used will normally be defined in the unit’s maintenance manual. Cables Wipe clean all exposed cables, and check for damage. If a cable shows signs of wear or ageing, contact Kongsberg Maritime for advice. Dehumidifier Place a suitably sized bag of desiccant material (silica gel or similar) into the unit to keep the electronic components as dry as possible. Coatings Spray the unit externally with a corrosion inhibitor (e.g. light oil) before packing. 311046/H 149 HiPAP 501/451/351/101 hull units Re-packing The unit should be stored and transported in its original packing material and/or crate. In the event that this material is not available, proceed as follows: Small units must be protected from damp by being placed within a plastic bag at least 0.15 mm thick. An appropriate quantity of desiccant material should be placed inside this bag, and the bag sealed. The sealed unit must then be placed in an appropriate carton or crate, and supported in the container by appropriate shock-absorbing insulation (polystyrene foam chips etc.). Large units must be placed in a suitable cardboard box or wooden crate. The unit must be protected against physical damage by means of shock-absorbing insulation mats. The box must be clearly marked with its contents, and must be stored in a dry and dust-free area. ESD precautions What is ESD? Electro-Static Discharge (ESD) is the transfer of an electrostatic charge between two bodies at different electrostatic potentials, caused either by direct contact or induction by an electrostatic field. The passing of a charge through an electronic device can cause localised overheating, and it can also “puncture” insulating layers within the structure of the device. This may deposit a conductive residue of the vaporised metal on the device, and thus create a short circuit. This may result in a catastrophic failure, or degraded performance of the device. ESD Protection during transport and storage Sensitive electronic equipment must be transported and stored in protective packing bags, boxes and cabinets. The equipment must NOT be transported or stored close to strong electrostatic, electro-magnetic or radioactive fields. Unpacking and servicing ESD sensitive equipment If it is necessary to open and touch the electronics inside the boxes/cabinets, then the following precautions MUST be taken: The working area must be covered by an approved conductive service mat that has a resistance of between 150 311046/H Equipment handling 50 kΩ and 2 MΩ and is connected directly to a reliable grounding point via its grounding cord. The service personnel involved must wear a wrist-band in direct contact with the skin, connected to the service mat. Printed circuit boards and other components should be placed on the conductive service mat during installation, maintenance etc. ____________________________________________________________ Caution If, for any reason, it is necessary to move the circuit board or components from the conductive service mat, they must be placed in an approved anti-static transportation container (e.g. static shielding bag) before transportation. ____________________________________________________________ During installation and servicing, all electrical equipment (soldering irons, test equipment etc.) must be grounded. Temperature protection If the unit must be protected against extremes of temperature, the carton/crate must be lined on all walls, base and lid with 5 cm thick polyurethane or polystyrene foam. These units will be identified as delicate in the applicable documentation. The package must then be clearly marked: ____________________________________________________________ Note Must not be transported or stored in temperatures below -5 degrees Celsius. ____________________________________________________________ Other units can normally be stored in temperatures between -30° C and +70° C, refer to the system’s technical specifications for details. Transducers must not be stored in temperatures below - 20° C and above + 60° C. 311046/H 151 HiPAP 501/451/351/101 hull units 11 TEST AND ALIGNMENT PROCEDURES This chapter presents checks, tests and alignment procedures that must be conducted on the hull unit before it is put into operational service. Purpose After the physical installation has been carried out, all the system units must be checked to ensure that the units have been installed correctly. This chapter contains the instructions and procedures required to ensure the system is installed correctly, is correctly set up and is safe to switch on and use. Topics Test certificate on page 152 Visual inspection on page 152 Test procedures introduction on page 153 Test certificates Once the testing engineer has performed or witnessed the performance of a test or part of a test, he should sign on the dotted line under each check/test to certify that the unit or system has passed that particular part of the procedure. The use of these fields is optional, but we recommend that they are properly filled in for future references. ____________________________________________________________ Note If the testing engineer is not satisfied with the standard of any part of the installation, he must contact the personnel who performed the installation to have the work rectified and brought up to the required standards. ____________________________________________________________ Visual inspections After the installation has been carried out, all the system units must be checked visually to ensure the system has been installed correctly. 152 311046/H Test and alignment The testing engineer must ensure that the units have been mounted in the correct locations, correctly orientated (that is, the right way up) and are correctly secured to the bulkhead/deck/mounting brackets. The inspection engineer must understand that correct installation of some parts of the Hull unit is critical to the safety of the vessel. Test procedures introduction In all cases the step-by-step instructions must be followed if the tests are to be trustworthy. In order to verify that the HiPAP® system work properly, the following tests must be carried out: Topics Inspection of the hull unit on page 154 Inspection of the Hoist Control Unit on page 158 Inspection of the Remote Control Unit on page 160 Cabling installation checks on page 162 Hull unit raise/lower manual checks on page 164 Electrical check on page 166 Remarks and signatures on page 170 Follow the procedures and fill in the tables. Once the system has been tested, sign the signature page (use the last page of this section). The test results will be: 311046/H OK when the test is done satisfactory. FAIL if the test fails. NA if the test is non-applicable. 153 HiPAP 501/451/351/101 hull units Inspection of the hull unit After the installation has been completed, all parts of the Hull unit must be checked to ensure a secure and safe installation.

Personnel - Experienced engineer from the yard’s quality assurance department. Installation supervisor. Vessel location - N/A. References - Drawings included in this manual. Special tools - None. Visual inspection of the cabling Refer to the cable plans and interconnection diagrams, and check all power and inter-connection cables. Any locally fitted plugs and connectors must also be checked to ensure the correct types have been used for the specific locations. (Sealed/spark-proof connectors in areas where flammable gasses may accumulate, etc.) Ensure all cable connections have been made according to the cable plan, and that all connections are tight and secure. Ensure all cables are correctly laid in conduits, or are otherwise protected according to the regulations and recommendations laid down by the vessel’s registering authority. Ensure all protective covers are fastened correctly. Cable connections and continuity After the cable connections have been completed and the visual inspection has been carried out, all the cable cores must be checked for correct connection and continuity. Refer to the cable plans and interconnection diagrams, and check all interconnection cables. Any locally fitted plugs and connectors must also be checked for shorts or open circuits. Ensure all cable connections have been made according to the cable plan, and that all connections are tight and secure. 162 311046/H Test and alignment ____________________________________________________________ Warning These checks must be completed before any power is switched onto the system. ____________________________________________________________ Procedure The check procedure will require pairs of engineers, equipped with the appropriate cable plans and wiring diagrams, two-way communication devices and tool kits. The “tester” will require continuity test equipment and the assistant will require a suitable shorting strap. ____________________________________________________________ Note The exact resistance values will depend on the type and lengths of the cables and the units to which the cables are connected. If in doubt, check with the manufacturers. ____________________________________________________________ Follow the check procedure below for each cable core: 1 The test engineers must position themselves one at each extremity of the cable to be checked. 2 Good communications must be established. 3 Ensure the cable to be tested is not connected to any power source. ____________________________________________________________ Note If a cable terminates in a plug at the unit, the test will be more easily conducted if the plug is disconnected. ____________________________________________________________ 4 Select one pair of cable cores, and check that the cores are connected to the correct terminals in the unit. 5 The tester then connects his continuity tester to the two terminals in question and checks the continuity. ____________________________________________________________ Note If a low resistance exists between the two cores, this may indicate the cores are connected to circuits or units with low internal resistance. If this is the case, disconnect the cores from the terminal block and test again. The resistance should be approaching RW. If so: ____________________________________________________________ 6 311046/H The assistant then shorts the two cores together, and the tester repeats the test. The Resistance should be ≈ 0. 163 HiPAP 501/451/351/101 hull units 7 The assistant then removes the shorting strap, and the resistance should go up to ≈ ∞ again. 8 The tester then checks each core’s resistance to ground, (this should be ≈ ∞ ), and each core’s resistance to all the other cores in the cable, (this should be ≈ ∞ ). 9 Assuming the test results are correct, the cores must then be reconnected to the terminal block (if they had been removed), and the terminals checked to ensure they are correct and tight. 10 On completion, move on to the next pair of cores and repeat the tests till the entire cable has been checked.

Yard’s quality assurance department Signature Date Installation team supervisor Signature Date Hull unit raise/lower manual checks This procedure is a mechanical test during which the hull unit is operated manually. These test checks that the hull unit is free to move without striking any obstructions and that the transducer cables are not going to become caught on anything during the lowering and raising operations. This check is to be used before the hull unit is powered up for the first time, and after any major maintenance or replacement has been carried out on the unit. 164 311046/H Test and alignment ____________________________________________________________ Warning Before lowering the hull unit, ensure there is a sufficient depth of water beneath the vessel’s hull. If the vessel is in dry dock, check in the hull unit compartment and under the vessel to ensure no-one is working on the equipment and there are no obstructions. Rope off the area under the hull to ensure no one goes into the area while the hull unit is being operated. ____________________________________________________________ Logistics Safety - N/A.

Frequently asked questions
The hull unit allows the transducer to be lowered through the vessel's hull to a depth below aerated water and other sources of acoustic noise.
The main parts are the hoist motor and gearbox, gantry, shaft sleeve, transducer dock, transducer shaft, and gate valve.
A crank handle is provided which can be attached to one end of the motor shaft, to allow you to raise or lower the transducer manually.
Frequent inspections and greasing of the shaft sleeve are strongly recommended, particularly if the system is in frequent use.
