High voltage safety warning
Precautionary measures
The voltages used to power this equipment are
potentially lethal. Even 110 volts can kill.
Whenever possible, the following precautionary
measures must be taken before any work is
carried out inside the equipment:
• Switch off all high-voltage power supplies.
• Check the operation of any door interlocks
and any other safety devices.
• Completely discharge all high-voltage
capacitors.
It should be noted that interlocks and safety
devices are normally located only at regular
access points, and high voltages may be exposed
during dismantling.
3
If his heart is beating but he is not breathing,
commence artificial respiration. If the victim’s
heart is not beating, commence external cardiac
massage (ECM). Continue to shout for assistance
till someone arrives.
External cardiac massage
1
Kneel beside the victim. Place the heel of
one hand in the centre of his chest, at a
position half way between the notch
between the collar-bones at the top of his
chest, and the dip in the breast-bone at the
base of his rib cage. Place the other hand
on top of the first.
2
Keeping the arms straight and using your
entire weight, press down rapidly so that
the breast bone is depressed four- five cm,
then release the pressure. Repeat
rhythmically at a rate of one cycle per
second. This will be hard work, but keep
going. His life depends on YOU. Do not
worry about breaking his ribs - these will
heal if he survives.
Never work alone on high-voltage equipment!
First aid in the event of electric
shock
Normally, even a high voltage electric shock will
not kill instantly. The victim can still be revived
even when his breathing and heart-beat have
ceased.
Could YOU save someone’s life?
In the event of electric shock, the correct actions,
performed quickly may well save the victim’s
life. Make sure you know what to do!
Check if the victim is breathing. If not,
check if his heart is beating. The pulse is
normally easily found in the main arteries
of the neck, either side of the throat, up
under the chin.
Immediate action:
While shouting for help, remove the source of
power from the victim. Switch off the supply if
possible, or using a dry, non-conductive material
(rubber gloves, broom handle etc.) to insulate
yourself, separate the victim from the source. If
the voltage exceeds 1000 volts, switch off the
supply and be ready to catch the victim. Take
care- do not become a victim yourself.
Commence first aid on the spot. Continue to shout
for assistance till someone arrives.
1
Lay the victim flat on his back and loosen
any tight clothing (collar, tie, belt etc.).
2
Open his mouth and check for and remove
any false teeth, chewing gum etc.

Kneel besides the victim’s head. Place one
hand under his neck and lift, allowing his
head to fall back. This will lift his tongue
and open the air passage in his throat.
Place the palm of the hand on his forehead
to maintain the ”chin-up” position.
Using the index finger and thumb of the
same hand, pinch the victim’s nostrils
closed. Open his mouth.
Take a deep breath and cover his mouth
with yours. Blow steadily into his lungs to
expand his chest. Remove your mouth
from his to allow the air to escape from his
chest. You should be able to see his chest
deflate.
Repeat the ”inflation-deflation” cycle at a
rate of about 12 cycles per minute till the
victim begins to breath normally again.
If started quickly and performed correctly, the
resuscitation methods described will keep a
sufficient volume of oxygenated blood flowing
trough the victims body to allow full recovery.
Proficiency in the resuscitation methods can only
be achieved trough training. All personnel
concerned should attend courses on a regular
basis. Remember, someone’s life could depend on
you.
Do you know what to do?
Combining ECM and artificial
respiration
If you are alone, perform one cycle of artificial
respiration for every five cycles of ECM. This
will be hard work, but keep going. His life
depends on you!
If there are other people available to help, one
should perform the ECM while one performs the
artificial respiration for every five cycles of ECM.
It will be much more efficient with two people.
Once the victim’s heart is beating and he is
breathing, roll him onto his side and support him
in that position. As consciousness returns he may
vomit, and this will allow any liquid to drain out
of his mouth.
Remove the victim to a hospital as soon as
possible, but do not interrupt the artificial
respiration and ECM cycles till his heart beat and
breathing returns.

Peripheral equipment
Required inputs
The Simrad SP90 sonar system requires input from both a speed
log and a course gyro. Inaccurate data from either of these
instruments will result in an incorrect indication of vessel and
target movement.
Speed log
The speed log parameters are:
• Pulse log: 200 pulses / nm.
• Serial line, standard NMEA 0183, RS-232
→
Also refer to (D)GPS below.
Course gyro
The course gyro parameters are:
• Serial line, standard NMEA 0183, RS-232
An optional gyro interface box for converting the following
synchro and stepping gyro signals can be ordered from Simrad:
• 3-phase synchro signal, 20 to 150 V L-L, 50/60/400 Hz, gear
ration 1:360 or 1:180
• 3-phase stepper signal, 20 to 150 V L-L, gear ration 1:360 or
1:180
→
Refer to page 6 for the Simrad order number.
Additional inputs
In addition to the pulse log input described above, the SP90
sonar provides a total of seven RS-232 serial lines. Since one is
used to interface the course gyro, the remaining six serial lines
may be used for:
• Differential Global Positioning System - (D)GPS
• Echo sounder
• Purse seine system
• Trawl system
• Current meter system
• Radio buoy system
Differential Global Positioning System - (D)GPS
A (D)GPS may be interfaced with the Simrad SP90 sonar to
establish the vessel’s position and provide cursor and marker
latitude and longitude.
851-164510 / Rev.E

Simrad SP90
Note that in addition to navigational data, the (D)GPS may also
be used for the input of speed log information. Most (D)GPS are
equipped to present course information, but this data is
generally too inconsistent to provide a stable sonar presentation.
The (D)GPS parameters are:
• GPS data: RS-232 Serial line, standard NMEA 0183.
Echo sounder
To provide depth information on the catch control page of the
sonar’s display, echo sounders may be connected:
• RS-232 Serial line, standard NMEA 0183

General installation requirements
Responsibility and approval
The Simrad SP90’s Hull Unit sleeve has been approved by Det
Norske Veritas (DNV) Classification society. Individual Hull
Unit installations must be approved on a case-by-case basis with
regard to the vessel’s national registry and corresponding
maritime authority. The shipowner and shipyard performing the
installation are responsible for obtaining 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).
Simrad recommends that the SP90 sonar is powered using an
Uninterruptible Power Supply (UPS). The UPS should have the
capacity to independently maintain power to the sonar 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.
Environmental requirements
All equipment, unless otherwise specified, must be protected
from temperature extremes and excessive humidity.
Compass deviation
Once the installation is complete, the vessel must be swung with
the sonar 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.
851-164510 / Rev.E
11
Simrad SP90
Dry docking
Make sure that ample clearance under the sonar trunk and/or
protection blister is provided when dry docking the vessel.
Avoid locating supporting blocks or structures in the vicinity of
this equipment.
Note:
The location of the sonar trunk and/or protection blister must be
noted on the vessel’s docking plan for future reference.
Wiring
The cable from the wheelhouse to the sonar room must be
supported and protected along its entire length using conduits
and/or cable trays. Note that the cable must not be installed in
the vicinity of high-power supplies and cables, antenna cables or
other possible sources of interferences.

Batteries
If the unit contains normal batteries, these may have been
disconnected/isolated before the unit was packed. These must
only be reconnected before the installation starts. Units
containing batteries are marked.
Caution:
Units containing lithium or alkaline batteries must be
handled separately and with care. Such units are
marked accordingly. Do not attempt to recharge such
batteries, open them or dispose of them by
incineration. Refer to the applicable product data
sheets.
Inspection and unpacking
Inspection
An inspection must be carried out immediately after the unit(s)
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 Simrad 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.
General unpacking procedure
Normal precautions for the handling, transportation and storage
of fragile electronic equipment must be undertaken.
Note:
16
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.
851-164510 / Rev.E
Introduction
• 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
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. Refer to the
precautions starting on page 22.
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.
Inspect the unit for damage before opening the plastic bag.
851-164510 / Rev.E
17
Simrad SP90
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.
Assuming all is well, open the bag and remove the unit.
Open the unit and check inside. Remove any packing and
desiccant material that may be inside.
Mechanical units
Mechanical units may be heavy. Using a suitably certified lifting
apparatus, lift the unit out of the crate and place it in a stable
position on the floor/work bench.
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.
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.

851-164510 / Rev.E
Introduction
Storage
Pre-installation storage
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 (eg. 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.
Note:
Do not break the seal to open a circuit board package before the
board is to be used. If the board package is returned to the
manufacturers with the seal broken, the contents will be
assumed to have been used and the customer will be billed
accordingly.
The unit must be installed in its intended operating position as
soon as possible after unpacking.
If the unit contains normal batteries, these may have been
disconnected/isolated before the unit was packed. These must
then be reconnected during the installation procedure. Units
containing batteries are marked.
Caution:
Units containing lithium or alkaline batteries must be
handled separately and with care. Such units are
marked accordingly. Do not attempt to recharge such
batteries, open them or dispose of them by
incineration. Refer to the applicable product data
sheets.
After use storage
Introduction
If a unit is removed from its operating location and placed into
storage, it must be properly cleaned and prepared before
packing.
Cleaning cabinets
If a cabinet has been exposed to salt atmosphere while it was in
use, it must be thoroughly cleaned both internally and externally
to prevent corrosion.
851-164510 / Rev.E
19
Simrad SP90
• Wipe the cabinet externally using a damp cloth and a little
detergent. Do not use excessive amounts of water as the unit
may not be water tight. On completion, dry the unit
thoroughly.
• All surfaces must be inspected for signs of corrosion, eg.
flaking/bubbling paint, stains etc. Damaged or suspect areas
must be cleaned, prepared and preserved using the correct
preservation mediums for the unit. The mediums to be used
will usually be defined in the units’ maintenance manual.
• Open the unit, and using a vacuum cleaner, remove all dust
etc. from the unit. Great care must be taken to ensure the
circuit boards and modules are not damaged in the process.
Mechanical units
If a mechanical unit may have been exposed to a salt
atmosphere while it was in use, it must be thoroughly cleaned
both internally and externally to prevent corrosion.
• If the construction materials and type of unit permits, wash
the unit using a high-pressure hose and copious amounts of
fresh water.
Examples:
- The lower parts of hull units (outside the hull)
- Subsea units
• Ensure that all traces of mud and marine growth are removed.
Use a wooden or plastic scraper to remove persistent growth,
barnacles etc. On completion, dry the unit thoroughly.
Caution:
Do not use a high pressure hose in the vicinity of cables
or transducers. Do not use sharp or metal tools on a
transducer face.
• If the materials or type of unit prevents the use of a
high-pressure hose, wipe the unit using a cloth dampened
with water containing a little detergent.
Examples:
- The upper parts of hull units (inside the hull)
- Hydraulic systems
• Do not use excessive amounts of water as some components
on the unit may not be water tight. Wipe off the detergent
with a damp cloth, then dry the unit thoroughly.
20
851-164510 / Rev.E
Introduction
• All surfaces must be inspected for signs of corrosion, eg.
flaking/bubbling paint, stains etc. Damaged or suspect areas
must be cleaned, prepared and preserved using the correct
preservation mediums. The mediums to be used will
normally be defined in the unit’s maintenance manual.
Cables
Wipe clean all exposed cables, and check for damage. If a cable
shows signs of wear or ageing, contact Simrad for advice.
Internal batteries
If the unit contains batteries, these may discharge slowly during
storage. If the unit is to be stored for an extended period,
disconnect or remove all internal batteries.
A suitable piece of insulating material can be placed between
the battery and the electrical contacts to prevent electrical
discharge. The battery can then remain in the unit, reducing the
risk of it being misplaced during the storage period.
Caution:
Units containing lithium or alkaline batteries must be
handled separately and with care. Such units are
marked accordingly. Do not attempt to recharge such
batteries, open them or dispose of them by
incineration. Refer to the applicable product data
sheets.
Dehumidifier
Place a suitably sized bag of desiccant material (silica gel or
similar) into the unit to keep the electronic components as dry as
possible.
Coatings
Spray the unit externally with a corrosion inhibitor (e.g. a light
oil) before packing.
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.).
851-164510 / Rev.E
21
Simrad SP90
• 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
Electrostatic Discharge (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 50kΩ
and 2 MΩ, and is connected directly to a reliable earth point
via its earthing 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.
22
851-164510 / Rev.E
Introduction
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 earthed.
Temperature protection
If the unit must be protected against extremes of temperature,
the carton/crate must be lined on all walls, base and lid with
5 cm thick polyurethane or polystyrene foam.
These units will be identified as delicate in the applicable
documentation.
The package must then be clearly marked:
Note:
Must not be transported or stored in temperatures
below -5 degrees Celsius.
Other units can normally be stored in temperatures
between -30° C and +70° C, refer to the system’s technical
specifications for details.
Transducers must not be stored in temperatures below -20°C
and above +60°C.

2 INSTALLATION PLANNING
Note:
2.1
For installation in a previously installed trunk system, first read
the information about sonar room requirements. Then proceed
to the Hull Unit installation description.
Introduction
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.

SP90 Sonar room layout, example, page 29
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
coffer-dams
• Lines plan

2.2
Location of the Hull Unit
Fore and aft
The Hull Unit should preferably be located within 1/10 to 1/3
the vessel’s Length Between Perpendiculars (LBP) measured
from its Forward Perpendicular (FP). Deviations from this rule
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 off-set from the
vessel’s centre line, make sure that transducer transmission and
reception will not be obstructed by the keel.
(A) = Water level at normal trim
(B) = Welding marks to indicate hull unit location when docking
(C) = Length Between Perpendiculars (LBP)
(D) = 1/3 to 1/10 of LBP
851-164510 / Rev.E
25
Simrad SP90
Important considerations
The Hull Unit trunk must be installed so that it will be vertical
under normal operating conditions. The primary sources of
underwater disturbance (other than a vessel’s main propeller and
bow/sternthruster) that affect transducer reception are:
•
•
•
•
•
•
•
Main or bilge keels
Zinc anodes
Cooling elements protruding from the hull
Equipment such as sonar transducers and pitot 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.
26
851-164510 / Rev.E
Installation planning
2.3
Sonar room requirements
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.
Lifting
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 Trunk and
Hull Unit mounting and also may be used for service of the
equipment in the future.
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.
851-164510 / Rev.E
27
Simrad SP90
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.
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).
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 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.
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.
Lighting
The sonar room should be equipped with suitable lighting to
simplify the installation and aid future maintenance.
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 as indicated.
Decking
Once the installation has been completed, the sonar room should
be suitably decked without restricting access to the equipment.

Sonar trunk
3 SONAR TRUNK
3.1
Introduction
The sonar trunk provides the physical foundation for the entire
hull unit gantry. The trunk further penetrates the hull, and it is
therefore a cruicial part of the hull unit assembly. In order to
ensure proper sonar operation, the location of the sonar trunk
must be carefully selected.
A DnV approved trunk with a blind cover 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.
The installation shipyard must provide all necessary installation
drawings, and if required, these must be approved by the
applicable authorities.

Mounting the 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.
Note:
Remove the gasket on the top flange during welding.
Parallel to the
centre line
Figure 3 Orientation of the sonar trunk
(CD16001D)
The height from the top of the trunk flange, to the underside of
the protection blister, must be as shown in the referenced
figures.
The top flange must be parallel to the construction water-line in
both the fore-and-aft and athwartships directions.
The installation trunk must be welded to a doubling plate which
should 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 athwartships directions.

Protection
Protecting 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.

4 HULL UNIT
4.1
Introduction
The hull unit is a crucial part of the sonar system. Due to its
physical size and weight, and the fact that the trunk penetrates
the vessel hull, it is very important that the hull unit is installed
and secured properly.
This chapter describes the physical installation of the hull unit.

Unpacking
Warning:
Do not remove the transducer protection from
the transducer until just before the Hull Unit is to
be lowered onto the trunk.
The transducer is specially protected to prevent damage during
transport and installation of the Hull Unit, and should remain
attached while it is being manoeuvred into the sonar room.
When unpacking the Hull Unit, first remove the top cover of the
wooden box, then pull out the nails marked with Indian ink.
Fasten the lifting device to the two lifting eye bolts on top of the
gantry and lift the Hull Unit (with transducer protection in
place) carefully out of the transportation box.
40
851-164510 / Rev.E
Hull unit
4.4
Mounting
The Hull Unit should normally be oriented with the
hoisting/lowering motor pointing aft. If this orientation makes
the Motor Control Unit attached to the Hull Unit difficult to
access, the Hull Unit may be oriented in the most suitable
position.
Note:
The Motor Control Unit must never be disconnected from the
Hull Unit.

Simrad SP90
4.5
Bleeding air
To avoid damage to the transducer by the transmission in air
inside the trunk, a pipe with a minimum inside diameter of 10
mm must be attached to the air bleeding cock. This vent should
be run with continuous rise to the main deck or through the
vessel’s side. Make sure the air bleeding cock is opened.

4.6
Mechanical support
To ensure the safety of the sonar system and the vessel, it is very
important that the mechanical support of the hull unit gantry is
satisfactory.
To prevent unwanted vortex induced vibration, the Hull Unit
must be secured to the bulkhead. Use the two pre-drilled holes
on the gantry to mount support brackets in the fore-and-aft and
sideways direction. It must be possible to remove the support
brackets if maintenance is required.

Introduction
Note:
The Transceiver Unit must be mounted as a complete unit. The
door must not be opened until the unit is securely fastened to the
bulkhead.
Before mounting the Transceiver Unit, observe that the distance
between the Hull Unit and the Transceiver Unit is restricted by
the flexible transducer cable joining the two. Remember to take
into consideration the slack necessary to lower the transducer.
Caution:
Do not fasten the transducer cable to the Transceiver

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 metre) 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 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.

Cable layout
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.
Grounding
All metallic cable coverings (armour, metallic sheathing etc.)
must be electrically connected to the vessel’s hull at both ends
except in the case of final sub-circuits where they should be
connected at the supply end only.
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.
851-164510 / Rev.E
85
Simrad SP90
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
sleeve-terminations 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.
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.

8 PERIPHERAL EQUIPMENT
8.1
General
Introduction
It is not necessary to make the connection of the peripheral
equipment before the start-up procedure is finished, and this
equipment may therefore be connected later. However, do not
connect the termination plugs for the auxiliary equipment to the
Sonar Interface Unit before mentioned in a later chapter.
Required inputs
The SP90 sonar system requires input from both a speed log
and a course gyro. Inaccurate data from either of these
instruments will result in an incorrect indication of vessel and
target movements.

Speed log connection
Overview
The sonar can read the speed information from one of the
following three sources (tick off for the type which will be
connected):
• Pulse log (200 pulses/nautical mile)
• Speed log with RS-232 serial line output
• (D)GPS serial line (RS-232)
The connection of these different sources are described in the
following chapters.
Sonar Interface
Unit TB8
Speed log +
For any type of pulse log output (relay, open collector, or
opto-coupler), the output must be free from other connections.

Speed log with RS-232 output
The sonar can also read the speed log data from a RS-232 serial
line with a standard NMEA 0183 telegram format. The telegram
can contain both the speed and the course data.
Refer to the cable connection drawing for termination of the
serial line data in the Sonar Interface Unit.
For connection to the speed log, refer to the applicable log
documentation.
Speed data from (D)GPS (RS-232)
The (D)GPS output data will normally contain the speed log
information. In such case, this serial line can be used for both
the position and speed data.

Course gyro connection
Overview
The SP90 sonar can read the course information from an
RS-232 serial line. In case where only a 3-phase synchro or
stepper signal is available, an optional Gyro Interface Unit must
be used for converting these signals to RS-232 serial line
format.
Gyro with RS-232 serial line output
The course data on the RS-232 serial line must be on a standard
NMEA 0183 telegram format. The telegram can contain both
the speed and the course data.
For connection to the course gyro, refer to the applicable gyro
documentation.
Gyro with 3-phase synchro or stepper output
If only a 3-phase synchro or stepper signal is available, an
optional gyro interface unit must be used to convert these
signals to RS-232 serial line format. An LR40 Digital Gyro
Repeater may be used for interfacing the following signals:
• 3-phase synchro signal, 20-115V L-L, 50/60/400 Hz, gear
ratio 1:360 or 1:180
• 3-phase stepper signal, 20-115V L-L, gear ratio 1:360 or
1:180
The LR40 Digital Gyro Repeater can be delivered from Simrad
on part number 298-078535. For connections to the LR40
Digital Gyro Repeater, refer to the LR40 Instruction Manual.

(D)GPS connection
A (D)GPS may be connected to the SP90 sonar to indicate the
latitude and longitude position of the vessel, cursor, markers and
targets. In addition to the navigational data, the (D)GPS may
also be used for the input of the speed log information. Most
(D)GPS systems are equipped to present the course information,
but this data is generally too inconsistent to provide a stable
sonar presentation.
The sonar can read the (D)GPS data from an RS-232 serial line
with a standard NMEA 0183 telegram format.
For connection to the (D)GPS log, refer to the applicable
(D)GPS documentation.

Trawl system connection
The SP90 sonar can read the trawl data from a Simrad FS Trawl
sonar or ITI (Integrated Trawl Instrumentation) system. The
communication is achieved using a RS-232 serial line.
When connecting the FS Trawl sonar to the SP90 Sonar
Interface Unit the trawl depth will automatically be shown in
accordance with the surface, targets and bottom in the vertical
modes on the sonar.
When the ITI trawl system is connected to the SP90 sonar, the
information exchanged between the ITI and sonar is:
ITI to sonar:
• Trawl position relative to vessel
• Depth of trawl below surface
• Trawl headrope to footrope distance
• Trawl door spread
• Trawl filling
• Water temperature at trawl
Sonar to ITI:
• Position of target or marker
For connection to the trawl system, refer to the RS-232 output
in the applicable trawl system documentation.

Refer to the plot provided on page 162.
This noise/speed curve can give a picture of the ship’s best
search speed.
Problems with flow noise
In case of very high ship noise levels, the RCG function will
automatically regulate the receiver gain down. This lower gain
will then cause a reduction in the receiving range.
To find out if this high noise level is caused by flow noise from
the vessel’s hull or by the engine/propeller, perform the
following test.

Enter the noise level for 0 degrees bearing from the Noise
measurements table into the column for Stable speed in
the Noise verification table.
→
The Noise measurement table is given as table 8 on page

The Noise verification table is given as table 9 .
From 0 knots, give full engine thrust, and make a readout
of the noise level for Acceleration when the vessel
reaches each of the listed speeds. Enter the readouts into
the table.

By comparing these three plots it should be possible to sort out
if the main noise is caused by flow noise or engine/propeller
noise.
If the main noise is caused by flow noise, the ship’s hull should
be thoroughly inspected during next docking. If the noise is
caused by the engine propeller, ensure that the propeller is not
chipped or corroded.

NMEA 0183
The NMEA 0183 Standard is the most common protocol used
for receiving and transmitting sensor data. The following
approved sentence structure are used for all NMEA data:
$aaccc,c—c*hh<CR><LF>
For some telegrams received from other Simrad equipment, the
$ character is replaced by the @ character.
According to the NMEA standard, the checksum field may not
be used.

Trawl systems
The SP90 interfaces a trawl system via Ethernet or on a serial
line. The serial interface uses either the NMEA 0183 standard,
or Simrad’s version of it. In the Simrad version of NMEA
telegrams, the Start Of Sentence delimiter $ is replaced with @.
The following trawl systems are interfaced: ITI, FS900 and
FS3300.
Note:
Other telegrams than trawl may be received from the ITI, since
this system may be used as a telegram router.
