Page 31 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.
Page 32 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.
Page 33 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.
Page 34 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.
Page 35 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.
Page 36: Installation Planning
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.
Page 37: Location Of The Hull Unit
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.
Page 38 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: •...
Page 39: Sonar Room Requirements
Installation planning 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.
Page 40 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.

Page 52: Unpacking
Simrad SP90 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.
Page 53: Mounting
Hull unit 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.
Page 54: Bleeding Air
Simrad SP90 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.
Page 55: Mechanical Support
Hull unit 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.
Page 56: Transducer Alignment
