Simrad SX95 Hull Unit
The hull unit is located in the sonar room, close to the transceiver. It is mounted on a mounting trunk, which accommodates the transducer when the sonar is switched off. As the transducer shaft penetrates the ship’s hull, it is required that all personnel handling installation and service are familiar with the hull unit’s main parts and operational principles.
AThe hand crank is used for manual hoisting and lowering of the transducer shaft. When not in use, the hand crank is stored inside the Motor Control Unit.
BThe identification label provides the hull unit’s name, as well as its registrationand serial numbers.
CThe hoisting motor is used to lower and hoist the transducer shaft. In order to rotate in both directions, the motor is powered by a 3-phase voltage. The motor is controlled by the Motor Control Unit.
DThe Motor Control Unit controls the hoisting motor. It also contains the sensor required for sonar beam stabilization.
EThe hoisting unit performs the hoisting and lowering of the transducer by converting the rotary motion from the motor to a vertical linear motion for the transducer shaft.
FThe transducer shaft sleeve supports the transducer shaft and ensures that the assembly is water tight. The area between the upper and lower bearings is also used as a grease reservoir for the lubrication of the bearings and for additional water tightening.
GThe mounting flange provides mechanical fastening of the hull unit to the mounting trunk. A gasket is used to make the assembly watertight.
HThe mounting trunk accommodates the transducer when the transducer is retracted.
Note
The trunk is not included in the standard delivery of the sonar, but can be ordered as an option.
IThe transducer has a cylindrical shape. It contains 256 separate wide-band transducer elements.
JThe transducer cable contains two wires for each transducer element. All are housed in a flexible hose which ends up in a plug unit for connection to the Transceiver Unit.
KThe transducer shaft penetrates the shaft sleeve, and allows the transducer to be lowered and hoisted. The transducer is connected to the lower end of the transducer shaft using a special plug.

LThe air bleeding cock is provided to avoid air inside the trunk. We recommend that a pipe is connected to this cock with continuous rise to the main deck or through the vessel side.
MA number of zinc anodes are mounted below the mounting flange to prevent corrosion on the transducer shaft.
The Simrad SX90 sonar may be delivered with any one of several different hull unit models.

INSTALLATION PLANNING
Note
For installation in a previously installed trunk system, first read the information about sonar room requirements. Then proceed to the Hull Unit installation description.
This chapter provides the marine engineers responsible the information necessary to plan and install the sonar’s hull unit according to Simrad’s requirements. Correct installation of the sonar 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 is for use in selecting the best location for the transducer and includes a brief description of areas to be avoided.
Note
All installation drawings must be supplied by the shipyard. 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.
Simrad offers free advice for installation planning. Proposed arrangements may be sent for commentary or suggestions supplied by Simrad. The following drawings should be submitted should assistance be requested:
•General arrangement
•Body plan and drawings of relevant bottom tanks and cofferdams
•Lines plan
Topics
•Location of the hull unit on page 16
•Sonar room requirements on page 17
•Sonar room arrangement example on page 20

Simrad SX95
The hull unit should preferably be located within 1/3 to 1/10 of the vessel’s Length Between Perpendiculars (LBP) from its
Forward Perpendicular (FP). Deviations should not be made without consulting Simrad.
The hull unit may be located on the Centre Line (CL) of the vessel, or alongside its keel. If the installation is offset from the vessel’s centre line, make sure that transducer transmission and reception will not be obstructed by the keel.

BWelding marks to indicate hull unit location when docking
CLength Between Perpendiculars (LBP)
D1/3 to 1/10 of LBP
The installation trunk must be installed so that it will remain vertical under normal operating conditions. The primary sources of underwater disturbance (other than a vessel’s main propeller and bow/stern thruster) that affect transducer reception are:
16 |
319568/B |
Installation planning
•Main or bilge keels
•Zinc anodes
•Cooling elements protruding from the hull
•Equipment such as sonar transducers and pilot tubes
•Sea chests
•Overboard discharges
•Dents in the hull
All appendages to the hull, indentations and pipe in/outlets are potential sources of underwater noise. They may act as resonant cavities amplifying noise at certain frequencies, create cavitation or turbulence. Transducers should not be located in the vicinity of such objects and especially not immediately aft of them.
It is strongly recommended to use a dedicated compartment to house the hull unit and sonar transceiver unit. These two units must also be installed relatively close to each other due to the limited length of the transducer cables. Observe these minimum sonar room requirements to obtain suitable working conditions for sonar installation, use and maintenance.
The following physical properties must be taken into consideration when the sonar room is planned:
•Size
•Access hatches
•Lifting
•Deck
The sonar room must be dimensioned to house both the hull unit and the transceiver unit. This is due to the limited length of the flexible hose protected cabling (approximately 3.5 m) connecting these two units. A well designed sonar room reduces the risk of corrosion and simplifies maintenance increasing system reliability. The sonar room should 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 should be designed so that the equipment can be removed without being disassembled.
319568/B |
17 |
Simrad SX95
An attachment point, rated at a minimum of two -2- tons, for supporting a lifting device should be located above the hull unit. This permanently installed fixture will facilitate installation trunk and hull unit mounting, and also may be used for future equipment maintenance or replacement.
Once the installation has been completed, the sonar room should be suitably decked without restricting access to the equipment.
The following environmental properties must be taken into consideration when the sonar room is planned:
•Heating
•Insulation
•Ventilation
The sonar room should 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.
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.
The sonar room should be connected to the vessel’s ventilation system. If this is not possible, two 3-inch vents must be provided from the sonar room to the main deck. In the sonar room, the air inlet should be located in close to the deck and the outlet as high as possible. A funnel shaped drip-collector should 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 of the equivalent.
18 |
319568/B |
Installation planning
The following electrical requirements must be taken into consideration when the sonar room is planned:
•Conduit
•Bilge pump
•Lights
If the cable between the wheelhouse and the sonar room passes through hatches or areas where it may be damaged, it should be run through a conduit (two inch conduit is recommended).
The sonar room should 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.
The sonar room should be equipped with suitable lighting to simplify the installation and aid future maintenance.
The following special requirements must be taken into consideration when the sonar room is planned:
•Air vent pipe
•Precautions for dry docking
An air vent conduit with a minimum of 10 mm internal diameter must be attached to the air bleeding cock on the hull unit. The pipe should be laid with continuous rise to free air on deck or through the ship’s side.
Note
Through-hull modifications are subject to approval by the vessel’s national registry and corresponding maritime authority. The shipowner and shipyard are responsible for obtaining installation approval.
Make sure that ample space is provided between the vessel and dry dock for system installation.
To facilitate future dry docking, mark the position of the installed trunk on the ship drawings as well as on the hull.

The sonar trunk provides the physical foundation for the entire hull unit gantry. The trunk further penetrates the hull, and it is therefore a crucial part of the hull unit assembly. In order to ensure proper sonar operation, the location of the sonar trunk must be carefully selected.
A trunk with a blind cover – approved by Det norske Veritas (DnV) – can be ordered from Simrad as an optional delivery, or it may be manufactured by the installation shipyard based on the drawings in this manual and the properties of the hull.
Note
The installation shipyard must provide all necessary installation drawings, and if required, these must be approved by the applicable authorities.

The height from the top of the trunk flange to the underside of the protection blister must be selected as shown in the referenced figures.
Note
In order to obtain optimal sonar performance, the total height of the trunk must be as close as possible to its stated minimum height.
The top flange must be parallel to the construction waterline in both the fore-and-aft and athwartship directions.
The installation trunk must be welded to a doubling plate which must be at least 1.5 times as thick as the surrounding shell plating. The doubling plate’s final dimensions are to be governed by the

approved installation drawings supplied by the shipyard. The trunk must also be stiffened by welding knee-plates to it and the doubling plate in both the fore-and-aft and athwartship directions.
A steel blister must be fitted for protection. The blister shown is welded to the shell plating and then filled with oil to prevent corrosion. This method provides excellent protection and simplifies maintenance.
As soon as all installation, welding and grinding has been performed, the trunk and the surrounding area should be primed and painted using a quality protective coating.
Observe the next two drawings, these illustrate the installation of the sonar trunk.
