SYSTEM DESCRIPTION
This chapter provides a brief description of the HiPAP hull unit
systems and a short description of each unit.
The purpose of the hull unit is to enable the transducer to be
lowered out through the vessel's hull to a depth below aerated
water and other sources of acoustic noise.

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.
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.
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.
401497/C
13
HiPAP 502/452/352/102 hull units
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.
____________________________________________________________
It is important that the shaft sleeve is kept watertight, and that
Note
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.
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.

401497/C
System description
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.
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.
Switch B - is operated when the gate valve is fully closed. In the
middle position no switch is operated.
401497/C
15
HiPAP 502/452/352/102 hull units
Note
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 2 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.

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
116.
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.

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.
26
401497/C
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.
401497/C
27
HiPAP 502/452/352/102 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 recommendation is for threads lubricated with antiseize lubricant. The recommended tightening torques for the
various sizes of threads is as follows:
Nut/bolt torques

HiPAP 502/452/352/102 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:
30
401497/C
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 larger DN700 gate valve will need a 1000 mm
diameter 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 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.

Mounting flange installation
The mounting flange is welded into a hole cut in the vessel’s
bottom and provides a secure base for the hull unit assembly.
• 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 700 mounting flange
The DN 700 mounting flange comprises a steel cylinder, topped
by a flange ring.
The flange ring contains 24 equally spaced holes, each bored to
receive M27 bolts. The holes are on a pitch circle diameter of
840 mm, with a pitch of 15°.

diameter of 460 mm, with a pitch of 22.5°.
→ See drawing in the Drawing file chapter from page 145.
The flange welded around the top of the cylinder enables a gate
valve to be bolted onto the top.
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:
401497/C
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.

12
Tighten the nuts to a final torque - see table on page 28.
____________________________________________________________
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 rigid hull structures 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.
____________________________________________________________

Installation
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.
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

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 via Ethernet from the computer.
The units and components are laid out as shown in the following

The HCU is fitted with six mounting lugs. Holes can be drilled
in the bulkhead and bolts, nuts and washers used to secure the
unit, or studs can be welded to the bulkhead and the unit secured
to these.
Unit location
The HCU will normally be mounted in the close vicinity of the
hull unit.
• The lengths of the system cables do not place any practical
restrictions on the distance between the HCU and the hull
unit into which it is connected.
• The HCU is designed to be mounted on a bulkhead, but can
be mounted directly onto the hull unit gantry if necessary.

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.

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
46
401497/C
Cables
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
401497/C
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 wires 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.
47
HiPAP 502/452/352/102 hull units
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
48
401497/C
Cables
•
•
•
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.
401497/C
49
HiPAP 502/452/352/102 hull units
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.
50
401497/C
Cables
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.

Cable information
Cabling from transducer to transceiver is separated in 2 parts.
• One part is protected inside the hull unit and goes from the
transducer to the junction box.
• The other part goes from the junction box to the
transceiver unit, and is the moving part of the transducer
cable. Then it is possible to replace this part if damaged, or
when connecting to another transceiver type.
− See the HiPAP 502/452/352/102 Instruction manual for
more information.
The cabling from the transducer to the junction box is
standard for all transceiver types. (It is made be 8 round flat
cables placed and protected inside the transducer shaft (installed
at delivery - various lengths, depending on type of hull unit more information).
The cabling from the junction box to the transceiver unit is
the same for all transducer types and hull units but it comes in
two different lengths.
Transducer cable connection
This unit can connect to the transducer with 2 different types of
cable.
• Transducer patch cable
• Old transducer cable with plug.

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.

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 water-tightness test before
breaking the watertight integrity of the hull unit.

Maintenance
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.

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:
• 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.

HiPAP 502/452/352/102 hull units
Water-tightness 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:
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
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.

Procedure
72
1
Switch off all power to the system and remove the system
fuses.
- Power to the unit can be switched off using breaker
F01. However this will not disconnect the mains
voltage from the unit, so we recommend that you also
remove the fuses in the ship's ac supply to the unit.
- Label the fuse panel to inform others that maintenance
work is being carried out.
2
Check that all cable glands are correctly and tightly
mounted into the unit, and seal on the cables passing
through them.
3
Check also that there is no tension on the cables.
4
Open the HCU.
5
Check for signs of condensation or corrosion.
- Dampness or corrosion indicates either that the
equipment room is not properly ventilated and dry, or
that the unit's door is not closed correctly. Investigate,
and correct the fault.
6
Check that all cable terminations are tight, and that there is
no indication of overheating.
- If a cable termination is not tight, the bad connection
will probably result in overheating, leading to more
serious damage.
7
Check that all component units (relays, breakers, circuit
boards etc.) are tight on their mounting rails.

Shaft sleeve disassembly
____________________________________________________________
Caution
If the shaft sleeve must be disassembled for any
reason, you are strongly recommended to ask for
assistance from Kongsberg Maritime. If the transducer
adapter is not replaced correctly, you risk losing the
transducer.
____________________________________________________________
To prevent water leakage and to ensure smooth raising and
lowering of the transducer, the shaft sleeve is fitted with:
At the upper end - Lion twin-set packing seals.
At the lower end – U-cup (NI300-170-15) packing seals and a
scraper.
The space between the seals is filled with grease to lubricate the
shaft and provide extra watertight security.
When the sleeve is sufficiently filled, a thin film of grease will
be observable on the transducer shaft.
____________________________________________________________
It is important that the shaft sleeve is kept watertight, and that
Note
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.

15
Perform a system test as necessary to ensure the
maintenance has been conducted successfully.
Test procedure
General checks
On completion of any maintenance on the hull unit, the system
must be checked to ensure the maintenance was successful and
to ensure the hull unit may be operated safely.
→ Refer to the hull unit raise / lower checks on page 138.
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 128.

10 EQUIPMENT HANDLING
This chapter describes how to transport, pack and unpack, clean,
preserve and store electronic, electro-mechanical and
mechanical units supplied by Kongsberg Maritime AS.
The units may be supplied as spare parts, or as parts of a
delivery.
Topics
→ Transportation on page 117
→ Re-packing on page 126
→ ESD precautions on page 126
→ Temperature protection on page 127
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.
401497/C
117
HiPAP 502/452/352/102 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.
118
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.).
401497/C
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 -20 °C, and not warmer than +65 °C.
- If other limitations apply, the crates will be marked
accordingly.
____________________________________________________________
Note
Transducers must not be stored in temperatures below -20 °C,
or higher than +65 °C.

Refer to the information on page 126.
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
120
401497/C
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.
____________________________________________________________

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 126.
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.

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.

401497/C
125
HiPAP 502/452/352/102 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
126
401497/C
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 °C.
____________________________________________________________
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 + 65 °C.

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 wires 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.

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 wires, and check that the wires 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 (i.e. <100Ω-10kΩ) exists between the two
wires, this may indicate the cores are connected to circuits or
units with low internal resistance.
If this is the case, disconnect the wires from the terminal block
and test again. The assistant then removes the shorting strap,
and the resistance should go up to ≈ ∞ Ω again.
____________________________________________________________
6
401497/C
The assistant then shorts the two wires together, and the
tester repeats the test. The resistance should be ≈ 0 Ω.
137
HiPAP 502/452/352/102 hull units
7
The assistant then removes the shorting strap, and the
resistance should go up to ≈ ∞ Ω again.
8
The tester then checks each core’s resistance to ground,
(this should be ≈ ∞ Ω), and each core’s resistance to all
the other wires in the cable, (this should be ≈ ∞ Ω).
9
Assuming the test results are correct, the wires 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 wires and
repeat the tests till the entire cable has been checked.

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.

____________________________________________________________
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.

Procedure
401497/C
1
Check around the hull unit and ensure there are no
obstructions liable to hinder the lowering or raising of the
unit.
2
If the vessel is in a dry dock, check under the vessel to
ensure the transducer will not strike an obstruction when it
is lowered.
3
Remove the hand crank lever from the hoist platform and
place it in position on the hoist motor shaft.
4
Release the motor brake by tightening the screw on the
side of the motor, and lower the transducer approximately
30 cm.
5
Reset the brake by slackening the screw.
6
Check that the cable is free to follow the transducer shaft
as it is lowered, and is not liable to be caught on any
obstructions.
- Remember that the cable may swing some distance
from the hull unit in rough seas, so check to the full
radius of the cable.
7
Repeat steps 1 to 6 until the hull unit is fully lowered.
139
