Simrad MS70

General supply conditions

The following supply conditions are applicable to this Simrad MS70 delivery.

Equipment responsibility

The shipyard performing the installation and/or equipment dealer becomes fully responsible for the equipment upon receipt unless otherwise stated in the contract.

The duration of responsibility includes:

• The period of time the equipment is stored locally before installation.

• During the entire installation process.

• While commissioning the equipment.

• The period of time between commissioning and the final acceptance of the equipment by the end user (normally the owner of the vessel which the equipment has been installed).

Unless other arrangements have been made in the contract, the Simrad MS70 guarantee period (as specified in the contract) begins when the acceptance documents have been signed

Receipt, unpacking and storage

Upon accepting shipment of the equipment, the shipyard and/or the dealer should ensure that the delivery is complete and inspect each shipping container for evidence of physical damage. If this inspection reveals any indication of crushing, dropping, immersion in water or any other form of damage, the recipient should request that a representative from the company used to transport the equipment be present during unpacking.

All equipment should be inspected for physical damage, i.e. broken controls and indicators, dents, scratches etc. during unpacking. If any damage to the equipment is discovered, the recipient should notify both the transportation company and Kongsberg

Maritime so that Kongsberg Maritime can arrange for replacement or repair of the damaged equipment.

Once unpacked, the equipment must be stored in a controlled environment with an atmosphere free of corrosive agents, excessive humidity or temperature extremes. The equipment must be covered to protect it from dust and other forms of contamination when stored.

For more information, see the appendix related to equipment handling.

331549/B

Simrad MS70

General installation requirements

The following installation requirements are applicable to this Kongsberg Maritime delivery.

Approval by classification society

The Simrad MS70 transducer installation must be approved by Det Norske Veritas

(DNV) or another classification society.

The shipowner and shipyard performing the installation are responsible for obtaining the installation approval.

Supply power

The supply voltage to the equipment is to be kept within ±10% of the installation’s nominal voltage. Maximum transient voltage variations on the main switchboard’s bus-bars are not to exceed -15% to +20% of the nominal voltage (except under fault conditions).

Kongsberg Maritime recommends that the Simrad MS70 is powered using an

Uninterrupted Power Supply (UPS) with sine wave output.

The UPS must have the capacity to independently maintain power to the system for a minimum of 10 minutes. This ensures that the system can be switched off in a controlled manner in the event of a power failure.

Compass deviation

Once the installation is complete, the vessel must be swung with the system in both the operative and inoperative modes. The shipowner and captain are responsible for updating the deviation table accordingly with regard to the vessel’s national registry and corresponding maritime authority.

Noise sources

The vessel’s hull, rudder(s) and propeller(s) should be thoroughly inspected in dry dock prior to installation.

Roughness below the water-line deformities in the shell plating and protruding obstacles can create underwater noise. These sources of turbulence must be smoothed or removed as best as possible. It is especially important that the propeller(s) is not pitted or damaged.

Dry docking

Make sure that ample clearance under the transducer and/or protection blister is provided when dry docking the vessel.

Avoid locating supporting blocks or structures in the vicinity of this equipment.

331549/B

Simrad MS70

Note

The location of the transducer and/or protection blister must be noted on the vessel’s docking plan for future reference.

Prior to dry docking, power down all hydroacoustic systems, and label each system accordingly to prevent accidental power on.

Remove circuit breakers if necessary.

Wiring

All cables running between system cabinets located in different rooms and/or on different decks must be supported and protected along their entire lengths using conduits and/or cable trays. Note that the cables must not be installed in the vicinity of high-power supplies and cables, antenna cables or other possible sources of interference.

For more detailed information about cables and wiring, refer to the basic cable requirements.

Installation planning

This chapter provides the marine engineers responsible for the installation the information necessary to plan the installation the Simrad MS70 according to Kongsberg

Maritime’s requirements.

Correct installation of the MS70 transducer is vital to the system’s performance.

Several variables must be taken into consideration, the most important of which is the vessel’s construction. This guide can be used to select the best location for the transducer, and includes a brief description of areas to be avoided.

Topics

• About installation drawings on page 21

• Where to mount the transducer on page 22

• Sonar room requirements on page 25

• Cabling requirements on page 26

About installation drawings

All installation drawings must be supplied by the shipyard performing the installation.

Note

The installation must be approved by the vessel’s national registry and corresponding maritime authority and/or classification society. The shipowner and shipyard performing the installation are responsible for obtaining and paying for installation approval.

Kongsberg Maritime offers free advice for installation planning. Proposed arrangements may be sent for commentary or suggestions supplied by Kongsberg Maritime. The following drawings should be submitted should assistance be requested:

• General arrangement

• Body plan and drawings of relevant bottom tanks and cofferdams

• Lines plan

331549/B

Simrad MS70

Where to mount the transducer

A single answer to the question where to locate the transducer cannot be given. It depends very much on the vessel’s construction, how the hull is shaped and how the water runs along the hull. There are however a number of important guide lines, and some of these are even conflicting.

Mount the transducer deep

Mount the transducer at a deep position on the hull. Consider the situations when the vessel is unloaded, and when it is pitching in heavy seas.

There are several reasons for this.

1 The upper water layers of the sea contain a myriad of small air bubbles created by the breaking waves. In heavy seas the upper 5 to 10 metres may be filled with air, and the highest concentrations will be near the surface. Air bubbles absorb and reflect the sound energy, and they may in worst cases block the sound transmission altogether.

2 Another reason to go deep is the cavitation in front of high power transducers.

Cavitation is the formation of small bubbles in the water due to the resulting local pressure becoming negative during parts of the acoustic pressure cycles. The cavitation threshold increases with the hydrostatic pressure.

3 The transducer must never be lifted free of the water surface. Transmitting into open air may damage the transducer beyond repair. Mounting the transducer at a deep position on the hull prevents this.

4 If the transducer is lifted up from the water during heavy seas, it may be damaged when the hull strikes back at the sea surface. This is especially important for low frequency transducers with large faces.

Mount the transducer midway

Mount the transducer midway between the bow and the stern to avoid heave effects

Heave is the vertical movement of the vessel. It disturbs the echo traces in the echogram, making a flat bottom appear as a wave. A transducer location in the middle of the vessel minimises the influence of the vessel’s roll and pitch.

Avoid protruding objects

Mount the transducer well away from protruding objects on the hull.

Objects protruding from the hull, such as zinc anodes, sonar transducers or even the vessel’s keel, generate turbulence and flow noise. Holes and pipe outlets are also important noise sources. They may act as resonant cavities amplifying the flow noise at certain frequencies.

Do not place an echo sounder transducer in the vicinity of such objects, and especially not close behind them.

331549/B

Installation planning

For the same reason, it is very important that the hull area around the transducer face is as smooth and level as possible. Even traces of sealing compound, sharp edges, protruding bolts or bolt holes without filling compound will create noise.

Avoid the boundary water layer

Mount the transducer at the forward part of the hull to minimise the effects from the boundary water layer.

When the vessel forces its way through the sea, the friction between the hull and the water creates a boundary layer. The thickness of the boundary layer depends upon vessel speed and the roughness of the hull. Objects protruding from the hull, and dents in the hull, disturb the flow and increase the thickness of the boundary layer.

The flow in this boundary layer may be laminar or turbulent. A laminar flow is a nicely ordered, parallel movement of the water. A turbulent flow has a disorderly pattern, full of eddies. The boundary layer increases in thickness when the flow goes from laminar to turbulent. The figure below illustrates the boundary layer of a vessel moving through the water.

Figure 4 Boundary water layer

A Turbulent flow

B Laminar flow

C Air bubbles in the water

Furthermore, air bubbles in the sea water are pressed down below the hull and mixed into the boundary layer. The boundary layer is thin underneath the forward part of the vessel, and increases in thickness as it moves towards aft. If the sides of the hull are steep, some of the air bubbles in the boundary layer may escape to the sea surface along the vessel sides. It is our experience that a wide and flat bottom, with a rising angle less than around 13 degrees, is prone to giving air problems for the transducer. In any case a transducer location in the forward part of the hull is preferred in order to minimise the influence of the boundary layer.

331549/B

Simrad MS70

Avoid all propellers

Mount the transducer far away from the propellers.

The propulsion propeller is the dominant noise source on most fishing vessels, research vessels, merchant vessels and pleasure crafts. The noise is transmitted through the sea water. For this reason, the transducer should be placed far away from the propeller, which means on the fore part of the hull. Positions outside the direct line of sight from the propeller are favourable.

On small vessels with short distances it is advised to mount the transducer on that side of the keel where the propeller blades move upwards, because the propeller cavitation is strongest on the other side. The cavitation starts most easily when the water flows in the same direction as the propeller blade, and that is to some degree the case at that side of the keel where the propeller blades move downwards.

Avoid all bow thrusters

Mount the transducer far away from the bow thrusters.

Bow thruster propellers are extremely noisy. When in operation, the noise and cavitation bubbles created by the thruster make the echo sounder useless, almost no matter where the transducer is installed. And when not in operation, the tunnel creates turbulence, and if the vessel is pitching, the tunnel may be filled with air or aerated water in the upper position and release this in the lower position.

In general, all transducers must be therefore placed well away from the bow thruster.

However, this is not an invariable rule. Certain thruster designs combined with its physical location on the hull may still offer suitable transducer locations near the thruster.

If you are in doubt, consult a naval architect.

Summary and general recommendations

Some of the above guide lines are conflicting, and each case has to be treated individually in order to find the best compromise. Generally the propeller noise is the dominant factor, and a recommended transducer location is in the fore part of the hull, with maximum distance from the bow equal to one third of the total length of the hull at the water line.

Figure 5 General recommendation for transducer location A Transducer

B Inclination angle

C Hull length at water line

D Maximum 1/3 of the hull length at water line (C)

331549/B

Installation planning

If the vessel hull has a bulbous bow, this may well be a good transducer location, but also here must be taken into consideration the flow pattern of the aerated water. Often the foremost part of the bulb is preferable.

Sonar room requirements

The “sonar room” is the compartment in which the Transceiver Unit and the Power

Supply Units are installed.

Observe these minimum requirements to obtain suitable working conditions for MS70 installation, use and maintenance.

Size and access

A well designed sonar room reduces the risk of corrosion and simplifies maintenance increasing system reliability.

• The sonar room must be dimensioned to house all the relevant cabinets that comprise the Simrad MS70.

• The physical distance between the transmitters and the transducer is limited due to the length of the transducer cables.

• The sonar room must not be unnecessarily obstructed by girders, pipes etc. which might cause installation problems or impede maintenance.

• The sonar room must be accessible under all conditions at sea or at a berth.

• All doors or hatches must be designed so that the equipment can be removed without being disassembled.

Heating

The sonar room must be equipped with heater, dimensioned to maintain the equipment within its environmental tolerances (at least 1000 W), installed close to the deck. Heating is also an effective method for reducing humidity.

331549/B

Simrad MS70

Insulation

Bulkheads must be insulated and provided with an interior wall to the deck. The insulation should be the minimum equivalent of 50 mm of rock-wool. In addition, piping passing through the space prone to condensation must be insulated.

Ventilation

The sonar room must be connected to the vessel’s ventilation system. If this is not possible, two 3” vents must be provided from the sonar room to the main deck. In the room, the air inlet must whenever possible be located close to the deck and the outlet as high as possible. A funnel shaped drip-collector must be mounted below the vent pipes to divert moisture to the bilge. On the main deck, the best ventilation is provided when the outlet pipe is at least four meters higher than the inlet pipe. To keep out sea water, rain and spray, the ventilation pipes should be fitted with goosenecks or the equivalent. If the vessel is likely to operate in tropical conditions, a suitable air conditioning system must be installed. This system must be able to provide an ambient temperature not exceeding the maximum operating temperatures for the cabinets installed in the room.

Cable protection

If the cables between the sonar room equipment and other system units located in different compartments on the vessel pass through hatches or areas where they may be damaged, they must be run through conduits (minimum 2” conduit is recommended).

Electrical installations and lights

The sonar room must be equipped with suitable lighting to simplify the installation and to aid future maintenance. A minimum number of electrical outlets must be provided for the system units and other equipment.

Bilge pump and decking

If the sonar room is located below the water line, it must be connected to the vessel’s bilge pump system. If this is not possible, a separate bilge pump for the sonar room must be installed. Once the installation has been completed, the sonar room must be suitably decked without restricting access to the equipment and the cables.

Cabling requirements

A detailed cable plan is provided for the installation of the Simrad MS70.

→ Cable plans on page 82

The cables fall into the following categories:

• Internal cables within the Transceiver Unit rack

• Ethernet cables between the Transceiver Unit rack and the Operator Station, and between the MS70 system and external network(s).

• Interface cables to external sensors

331549/B

Installation planning

• Transducer cables

The power cables from the three Power Supply Unit cabinets must be run in steel conduits.

→ Steel conduits for power cables on page 56

The majority of the cables are provided by Kongsberg Maritime, but certain cables (in particular the cables to the external sensors) must be provided by the installation shipyard.

Note

All electronic installations and corresponding wiring must be in accordance with the vessel’s national registry and corresponding maritime authority and/or classification society. If no such guidelines exist, we recommend that Det Norske Veritas (DNV) Report

No. 80-P008 «Guidelines for Installation and Proposal for Test of Equipment» is used as

a guide. Observe Basic cable requirements on page 200.

Transducer installation

Transducer description

The Simrad MS70 transducer is a short cylindrical container with the transducer array located at the bottom. The transducer cables penetrate the top of the cylinder.

The transducer is mounted with twelve -12- bolts with

M12 thread.

A mounting ring must be welded to the blister plate.

A clamping ring is then inserted sideways towards the mounting ring.

Figure 7 transducer

The Simrad MS70

The twelve screws penetrate the clamping ring, and are fastened in the mounting ring. Both rings are supplied by Simrad.

The transducer must be mounted so that it has a clear view within its coverage sector. It is also important that the transducer is mounted so that the water around it is not aerated.

Note

An accurate measurement of the final position and angular orientation of the transducer is always required after installation.

The risk of galvanic corrosion must be taken into account in the design of the mounting structure. Periodic inspection of the mounting screws and use of sacrificial anodes is required.

The transducer is provided with three sacrificial zinc anodes mounted to its top surface

(lid). These anodes must be replaced when 1/3 of their bodies have been spent. If it is difficult to access the zinc anodes after the transducer has been installed, additional anodes must be mounted inside the blister. These additional anodes must be in electrical contact with the transducer, but not with the blister and/or hull.

Note

The transducer - with the cables - is a delicate item. Great care must be shown during all handling.

Even minor damages to the transducer cable may cause water to penetrate both the cable and the transducer body. Further, a blow to the transducer face may easily damage one or more elements.

Transducer unpacking

The Simrad MS70 transducer is large and heavy. It is also a delicate precision instrument, and it must be handled with care during unpacking and installation. The following basic rules for transducer handling MUST be followed.

Note

Do not expose the transducer to direct sunlight!

Do not expose the transducer to excessive heat!

Do not use high pressure water, sand blasting or metal tools to clean the transducer face!

Do not use strong solvents to clean the transducer face!

How to lift the transducer out of its transport crate

The Simrad MS70 transducer is shipped in a large wooden crate. The crate has two

“rooms”, one to house the transducer, and one to house the cables. The transducer is placed with its “face” downwards. It rests on a protective cushion shaped to fit the transducer. Across the top of the transducer body, a wooden beam secures that it stays in place during transportation.

A The three M10 lifting eye bolts are inserted into these threaded holes.

Figure 8 The top side of the transducer array

Preparations

In order to lift the transducer out from its transportation crate, you will need a suitable crane. The crane must be able to carry the total weight of the transducer array and the cables. You will also need the necessary ropes and tackles, as well as three

M10 lifting eye bolts. In order to protect the transducer face while handling the array, you will also need a circular wooden plate with diameter 522 mm.

The weight of the transducer array is provided in the

Technical specifications chapter.

2 Remove the transport beam across the top of the transducer body.

3 Mount the three 10 mm lifting eye bolts.

4 Lift the transducer straight up and out of the crate. Support the cables during the lift to keep the transducer body from tilting sideways.

5 Place the protective wooden plate under the transducer body to protect its face.

Transducer installation procedure

Observe the following procedures to install the Simrad MS70 transducer array.

Installation principles

The Simrad MS70 transducer array is installed vertically in a retractable keel lowered below the vessel’s hull. A mounting ring (B) is welded to the side wall of the retractable keel (C). The transducer is pushed in sideways, and fits into the mounting ring with the transducer face (E) facing towards port. A clamping ring (B) is mounted sideways, and holds the transducer in place by means of 12 bolts (D).

The lifting eyes on the transducer must be removed prior to final installation.

B Watertight seal

C Allow the transducer cables to move freely up and down

D Secure the cables here

E Steel conduit

By default, each cable is 25 meters long. The cables are cut to fit each individual installation.

The cable must be properly supported both inside and outside the retractable keel.

On the inside, design a steel cable duct from the top of the keel to just above the transducer (A). On the top of the ducts, place a watertight seal (B) which also supports the total weight of the cables, both inside and outside the keel.

Outside the retractable keel, allow the cable to run smoothly up and down (C) when the keel is lowered and hoisted. The top of the external cable run must be properly and permanently secured (D), and the seal must be able to take the entire weight of the cables. It is also important to ensure that the cable run can move undisturbed up and down outside the keel. There must be no obstructions to prevent the cables from moving freely!

A second steel conduit (E) is used between the external cable support and the electronic equipment in the sonar room.

Min. 800 mm

Design of cable conduit

The cable conduit must be designed to fit each individual ship and retractable keel. The quality of the materials used, as well as the quality of the workmanship must be defined by the vessel owner and the installation shipyard.

If a watertight sealing is used, the design and quality of this sealing must be approved by the vessel’s classification society.

Simrad MS70

Transducer alignment

The Simrad MS70 is a precision instrument for scientific use. In order to produce data that are both detailed and correct, it is necessary to calibrate the survey vessel more accurately than what may have been a standard practice earlier. The results, with all measurements taken in a common vessel coordinate system must be entered as MS70 operational parameters.

The calibration tasks include:

• measurement of where sensors are located

• measurement of how sensors are oriented

• measurement of the water line vertical location

• alignment of angular measurement sensors

• determination of any offsets in sensor data

• determination of any time delays in sensor data

Topics

• Measurements on page 36

• Vessel coordinate system on page 37

• Sensor locations on page 38

• Measurement accuracy on page 39

• Transducer orientation on page 41

• Heading sensor calibration on page 43

• Alignment summary on page 43

Note

Calibration must be taken seriously. It is recommended that this task and the continued control of the soundings’ consistency is assigned to one motivated and qualified person in the organization. To achieve the best results, the calibration must be planned carefully, and monitored throughout the installation and the first sea trials. It is also recommended to repeat the calibration procedures with regular checks throughout the operation of the vessel.

Measurements

Observe this general introduction to the alignment task.

Objectives

The following measurements must be made after installation:

• the horizontal and vertical positions of the transducer array.

• the angular orientation of the transducer array

• the horizontal and vertical positions of the motion sensor

• the horizontal and vertical positions of the positioning system (radio or GPS antenna)

331549/B

Transducer installation

It is easiest to perform these measurements with the vessel in dry dock, the others may be done with the vessel berthed. It is however recommended to perform these when in dry dock

During the sea trials (SAT), calibration surveys are required as described in the MS70

Reference Manual. Based on the calibration parameters determined from these surveys, proper values are entered into the MS70 as operational parameters.

In order to check and verify the performance of the MS70 system, we strongly recommend that calibration surveys are performed at regular intervals, or prior to any large survey. If existing sensors have been replaced, or new sensors have been installed, a new calibration is always required.

Alignment of motion and heading sensors

The alignment of the motion sensor and the heading sensor must be adjusted so that they provide zero values for pitch, roll and heading with the vessel lying still with normal trim and a true North heading. It is recommended that this takes place in the dry dock.

Alternatively, the offsets from zero must be determined. This is easiest to do with the vessel berthed. Follow the procedures in the applicable sensor manuals.

Time delays

Any time delays of the motion sensor and positioning data from their time of validity to the time when they are available at the interface ports of the MS70 must be determined.

The information may be available from the sensor manufacturer.

Water line

Finally, the vertical position of the water line must be measured with the vessel in normal trim. This should preferably be done at normal survey speed, and must of course be repeated as the loading and hence the draft of the vessel changes.

Vessel coordinate system

A Cartesian coordinate system must be defined for the vessel. The following definition must be adhered to:

• X = forwards

• Y = to starboard

• Z = pointing downwards

There are no restrictions to where the coordinate system’s origo is located in the X and Y directions. In the Z direction however, the origo must be located on the water line.

Note

The sea surface with the vessel in normal trim defines the horizontal (X-Y) plane. The water line must therefore be marked on the hull with the vessel in normal trim before any dry docking.

331549/B

(CD017013D)

Reference points must be established on the vessel at selected positions. These are needed during measurements of the sensor positions. Visual markings at these positions should be prepared and noted on the vessel drawings with X, Y and Z coordinates in the vessel coordinate system.

Sensor locations

The MS70 transducer array must be located according to the guidelines given elsewhere in this manual. With regard to the location of other sensors the following guidelines should be followed, but otherwise should be chosen according to the manufacturer’s documentation.

Motion sensor

The system motion sensor should normally be mounted on the centre line of the vessel, either close to the MS70 transducer array, or close to the vessel’s centre of gravity.

The latter point is recommended if the sensor is used for other purposes than just with the MS70, or if its accuracy is sensitive to horizontal accelerations.

If there is any point in the fore-aft direction which does not change height with respect to the water line with changes in vessel speed, then this is the ideal location for the motion sensor. This will eliminate any errors from squat induced height changes which is not measured by current motion sensors.

Note

If the fore-and-aft distance between the transducer array and the motion sensor is larger than 20 m, the system accuracy may be degraded.

The motion sensor must be aligned with the vessel centre line.

331549/B

Transducer installation

Heading sensor

Alternatively, the offsets from zero must be determined. This is easiest to do with the vessel berthed. Follow the procedures in the applicable sensor manuals.

Note

The heading sensor must be aligned with the vessel centre line.

Measurement accuracy

The required measurement accuracies given below have been determined from considerations on how they contribute to total system accuracy. Any errors in these measurements shall not significantly contribute to depth or position errors in the soundings.

The motion sensor must be aligned (set up). The indicated roll and pitch angles from the sensor when the vessel has a normal trim (i.e. the coordinate system’s horizontal plane is horizontal) must be less than ±0.055° for both roll and pitch.

Note

The given accuracies are maximum values, and if easily achievable, better accuracies should be obtained.

5 Measure the pitch (with respect to the vertical plane) to an accuracy of ±0.1°.

Motion sensor

If the alongship distance between the transducer array and the Motion Sensor exceeds

5 m, its indicated pitch angle for vessel in normal trim must be less than 0.25°. If the distance is 20 m, the indicated pitch should be less than 0.05°. A linear interpolation for the other distance alternatives is recommended.

1 Measure the vertical location of the motion sensor to an accuracy of ±10 cm.

2 Measure the horizontal location of the motion sensor to an accuracy of ±5 cm.

331549/B

Transducer installation

Note

If the Motion Sensor performs lever arm correction to give heave data valid for another location than where it is actually mounted, it is this location which must be measured.

3 Set up the forward axis on the motion sensor with the X-axis of the vessel’s coordinate system to an accuracy of ±0.1°.

4 Set up the motion sensor such that the indicated roll and pitch angles from the sensor when the vessel has a normal trim (the coordinate system’s horizontal plane is horizontal) are less than ±0.05° for both roll and pitch.

Heading sensor

The heading sensor must be aligned with the X-axis of the vessel’s coordinate system to an accuracy of +0.255. If this is not possible, the resulting offset must be known to the same accuracy.

Positioning system

1 Measure the vertical location of the positioning system antenna with an accuracy of ±2 cm.

This is only required if the positioning system measures position in the vertical axis. This will be usually only be the case for real-time kinematic GPS systems and some optical positioning systems.

2 Measure the horizontal location of the positioning system antenna’s with an accuracy of ±5 cm or 20% of the positioning system’s accuracy.

Water line

Note

With the vessel in normal trim, that is with an indicated pitch angle of zero from the motion sensor, the distance to the water line may be measured anywhere on the vessel, but otherwise it must be measured at the alongship physical location of the motion sensor. The measurement should be taken on both sides of the vessel and averaged to remove any roll effects. Simultaneous measurements are required if the vessel is moving.

1 Measure the vertical distance to the water line with an accuracy of ±2 cm.

Transducer orientation

The MS70 transducer array is equipped with index marks to be used for measuring its orientation. A ruler oriented with the face index marks can be used to give the heading and pitch of the array. By making the ruler as a right-angle cross the roll may be measured.

331549/B

Simrad MS70

Coordinate systems

The heading of the transducer array is measured as the heading of the projection of a line through the face index marks into the horizontal plane of the vessel coordinate system. If the array is mounted in such a way that the X-axis is vertical, the heading angle must be measured as the heading of the Y-axis with 90° subtracted. See the definition below.

The measurement of roll and pitch is done in a coordinate system which is the vessel coordinate system rotated about the Z-axis so that its X-axis is pointing in the transducer’s heading direction.

• The pitch of the transducer array is measured as the angle in the vertical plane between the horizontal plane and the line through the index mark.

The pitch installation angle is measured between the X axis and the horizontal plane.

The angle is positive if the axis points upwards, and negative if it points down. The range is between -90° and +90°.

• The roll of the transducer array is measured as the angle in the vertical plane between the horizontal plane and a line on the face at right angle to the line through the index mark.

The roll installation angle is measured between the Y axis and the horizontal plane.

The angle is positive if the axis points downwards, and negative if it points up. The range is between -180° and +180°.

To determine if the roll installation angle is larger than +90° or smaller than -90°, consider how much roll was required to bring the transducer array into its final position.

Use the standard definition for roll direction.

The MS70 software converts the measured roll angle to a rotation angle. This is made with an arc sine calculation, and erroneous measurements or data entry may make this impossible. However, if the measurements are done accurately, this will never be a problem.

Making the measurements

The actual measurement of the installation angles may be done by two different methods:

1 The most accurate method is to use land surveying techniques, establish a horizontal plane, and do distance measurements to and in this plane.

2 The second method is to use an inclinometer to measure roll and pitch angles combined with distance measurements in the horizontal plane for heading. This method is easier, but it requires a sufficiently accurate inclinometer.

Which method is to be used must be determined by the facilities available. The use of land surveying techniques is the recommended method, and is especially appropriate on a new vessel where all sensor locations must be measured. The two other methods may be appropriate when installing an MS70 on a survey vessel where other sensor positions and orientations are already established. A prerequisite for using an inclinometer is of course that it is accurate enough.

331549/B

Transducer installation

Heading sensor calibration

It may not be possible to calibrate the heading sensor accurately enough through sea trials, so the calibration is normally done with the vessel berthed.

On the quay the geographical coordinates of two points must be known or measured so that the heading of a line on the quay can be established to an accuracy of better than

±0.1°. The distance from two points on the centre line of the vessel (fore and aft) are then measured so that the vessel’s heading can be calculated. The heading sensor is then aligned to this heading or its measured offset determined.

The vessel must be turned 180° as many times as necessary with the alignment or offset checked until the mean error is within the specifications of the heading sensor.

Alignment summary

The table below give a summary of the requirements to the accuracy of the measurements.

Transceiver Unit installation procedure

This procedure explains how to install the Transceiver Unit.

The Transceiver Unit is housed in a 19 inch commercial instrument rack.

The chosen method for mounting the cabinet must be determined by the installation shipyard and the customer. The cabinet may be welded to the deck and bulkhead brackets, or mounted using suitable bolts.

1 Position the U-shaped profiles below the Transceiver Unit to provide the recommended height.

2 Arrange the necessary brackets on the bulkhead to fit the shock absorbers.

Note that the outline dimension drawing shows the initial size of the shock absorbers. When the cabinet is complete with all electronics, the weight will compress the bottom shock absorbers slightly. You must take this into consideration when you arrange the mounting of the absorbers at the top of the cabinet.

3 Mount the bulkhead brackets for the shock absorbers.

4 Place the cabinet in its correct position, and mount it properly.

Mounting the TRXU racks

This procedure explains how to install the three TRXU racks into the empty wired frame of the transceiver cabinet.

Note

Due to the physical weight of the racks, minimum two persons must be allocated to do this task.

Standard workshop tools are required, as well as a torque wrench for Allen bolts.

Important

Each of the three TRXU racks are provided complete with all circuit boards and modules readily mounted. They are positioned at the top of the transceiver rack, one above each of the three air ducts.

The racks must be installed in the following order:

1 TRXU No.0 must be installed in the top position. There are eight TRX32 circuit boards in this rack, and they are identified with numbers 24 to 17.

2 TRXU No.1 must be installed in the middle position. There are eight TRX32 circuit boards in this rack, and they are identified with numbers 16 to 9.

3 TRXU No.2 must be installed in the bottom position. There are nine TRX32 circuit boards in this rack, and they are identified with numbers 8 to 0.

Each rack is mounted on a dedicated set of rails, and then secured with four front mounted racks bolts on each side of each TRXU rack.

The rails are already installed in the wired transceiver rack, and the bolts to be used are already placed in their holes. Each rail consists of two parts; one is mounted to the rack framework, and one is mounted to the side of the TRXU rack. During shipping, these side rails are however mounted inside the framework rails.

The bottom bolt on the right side of TRXU No.0 secures an earth strap to the top bolt on the right hand side of TRXU No.1. Similar, the bottom bolt on the right side of

TRXU No.1 secures an earth strap to the top bolt on the right hand side of TRXU No.2.

The HP ProCurve 2910 Ethernet switch holds 48 front mounted connectors. The connectors are numbered 1 to 48 as shown in the illustration.

Figure 34 HP ProCurve 2910 Ethernet switch connectors

Note

Although the Ethernet connectors on the switch appear identical, they are organized in two different logical groups. The Ethernet switch thus operates as a “dual” unit providing two separate networks. For this reason, the connections between the switch and the peripheral devices are not random. Observe the ports that are identified on the cable plan, and use these.

The two logical groups comprise the following ports:

• TRU LAN : Ports 1 through 32

• OS LAN : Ports 33 through 48

[W] Operator Station cables

These cables are used on the Operator Station.

• W1 / Display : This is a commercial display cable. It provides the connection between the computer and the colour monitor. The type of cable used will depend on the video format required by the display (VGA/SVGA/DVI).

• W2 / Mouse : This is a commercial cable, and in most cases, it is fixed to the mouse.

Ensure that the plug on the mouse cable is compatible with the computer (USB/PS2).

• W3 / Keyboard : This is a commercial cable, and in most cases, it is fixed to the keyboard. Ensure that the plug on the keyboard cable is compatible with the computer

(USB/PS2).

• W4 / AC mains to display : This is a commercial power cable, and in most cases, it is provided with the display.

• W5 / AC mains to computer : This is a commercial power cable, and in most cases, it is provided with the computer.

• W6 / Ship’s ethernet : A standard Ethernet cable with RJ45 connectors is used to connect the Operator Station to the ship’s network. This cable must be provided by the installation shipyard. In order to handle the bandwidth of the Ethernet communication, we strongly recommend that a Cat 6 Ethernet cable is used. This cable must be provided by the customer or the installation shipyard.

• W7–10 / Serial line interfaces : Standard serial line interfaces (RS232/RS422) may be used as required. One may be used as K1 External trigger

• W11–15 / Serial line interfaces : Other interfaces (USB, Firewire etc) may be used as required.

Note

Additional Dx Ethernet cable(s) are used to connect the Multibeam Operator Station

to the Transceiver Unit. For these specifications. see [D] Ethernet cables to external cabinets on page 101.

The Operator Station is equipped with a serial port adapter to provide multiple interfaces.

Transducer cables overview

A total of 25 transducer cables are brought up from the transducer array. Each cable is terminated in a large connector, and each connector plugs into its dedicated socket on the rear side of the TRXU transceiver subracks. The transducer cables are identified with numbers 001 through 025

All transducer cables are provided by Kongsberg Maritime.

Transducer cables

The MS70 transducer array is organised as follows:

• The array contains 25 quadrants

• Each quadrant contains 32 individual elements

• Each quadrant is connected by means of a separate cable to a dedicated TRX32 circuit board handling the 32 channels

Transducer cable pairs

There are 36 cable pairs in each transducer cable.

32 of these cable pairs are used for the elements in the module.

Cable pair 33 connects to a thermistor on the transformer circuit board in the transducer.

The last two cables pairs are not used, and these are cut.

Moxa CP134U-I Serial adapter setup

This section describes the Moxa CP134U-I 4–port optical isolated serial interface board.

This board is used on the Multibeam Operator Station to provide multiple serial line connections.

Serial line support

The 4-port serial board supports the following serial line interface formats:

• Port 1 : RS-232/422/485

• Port 2 : RS-232/422/485

• Port 3 : RS-422/485

• Port 4 : RS-422/485

By manufacturer default, all these serial connections are set to RS-422 format. In order to change this to RS-232 or RS-485 format, dedicated jumpers or DIP switches must be changed.

331549/B

125

Simrad MS70

Note

Note that only ports 1 and 2 support RS-232 format.

Jumper and DIP switch settings

Use the 10-pin jumper arrays and the two DIP switches to set ports 1 and 2 to RS-232,

RS-422, or RS-485. Use the two DIP switches to set ports 3 and 4 to RS-422 or RS-485.

• RS–232 : In order to use Port 1 ( COM2 ) or Port 2 ( COM3 ) as RS-232 interfaces, the relevant jumper arrays for Port 1 or Port 2 must be moved. Note that ports 3 and 4 do not support RS-232 format.

• RS-422 : All four ports can be set to RS-422 using the two jumpers and the right-hand

DIP switch S2.

• RS-485 : All four ports can be set to RS-485 using the two jumpers and the right-hand

DIP switch S2. Additionally, each port can be selected for a 2-wire or 4-wire connection type using the left-hand DIP switch S1.
