Hull unit main parts
The hull unit is l ocated 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.
Simrad SX95 Hull Unit
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 registration- and 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.
319568/B
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.

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
Installation planning
All installation drawings must be supplied by the shipyard. The
installation must beapproved 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

Location of the hull unit
Fore and aft
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.
Athwartships
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.

Important considerations related to noise
The installation trunk must be installed so that it will remain
vertical under normal operating c onditions. The primary sources
of underwater disturbance (other than a vessel’s main propeller
and bow/stern thruster) that affect transducer reception are:
319568/B
•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.
Sonar room requirements
Installation planning
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.
Sonar room physical properties
The following physical properties must be taken into
consideration when the sonar room is planned:
•Size
•Access hatches
•Lifting
•Deck
Size
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.
Access hatches
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/B17
Simrad SX95
Lifting device
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.
Deck
Once the installation has been completed, the sonar room should
be suitably decked without restricting access to the equipment.
Sonar room environmental requirements
The following environmental properties must be taken into
consideration when the sonar room is planned:
•Heating
•Insulation
•Ventilation
Heating
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.
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 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.
18
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.
319568/B
Installation planning
Sonar room electrical requirements
The following electrical requirements must be taken into
consideration when the sonar room is planned:
•Conduit
•Bilge pump
•Lights
Conduit
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).
Bilge pump
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.
Lights
The sonar room should be equipped with suitable lighting to
simplify the installation and aid future maintenance.
Sonar room special requirements
The following special requirements must be taken into
consideration when the sonar room is planned:
•Air vent pipe
•Precautions for dry docking
Air vent pipe
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.
Precautions f or dry docking
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.

SONAR TRUNK INSTALLATION
The sonar trunk provides the physical foundation for the entire
hull unit g antry. 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.

Mounting the sonar trunk
The location of the sonar trunk must be carefully selected.
Note
Note the orientation of the centre line of the trunk with regard to
the mounting bolts.
Remove the gasket on the top flange during welding.

µ
Sonar trunk installation
µ± °1
Parallel to
centre line
(CD015415-003)
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
319568/B23
Simrad SX95
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.
Sonar trunk protection
Protecting the blister
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.
Corrosion protection
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.
Sonar trunk installation principles
Observe the next two drawings, these illustrate the i nstallation
of the sonar trunk.
