Sonar room requirements

The sonar room should be dimensioned to house the Hull Unit

and the Transceiver Unit. This because the length of the

flexi-hose protected cabling from the Hull Unit to the

Transceiver Unit is limited to approximately 4 meters.

By installing the units in a well designed sonar room, the risk of

corrosion is reduced, the maintenance is simplified, and the

reliability is increased.

A suggested arrangement of the sonar room is shown in figure 2.

The free space should not be obstructed by girders or pipes etc.,

which might cause problems for the installation and

maintenance work.

Access hatches

The sonar room must be accessible under all conditions, and the

doors or hatches should be so designed that the installed units

can be removed without being disassembled. A tackle carrier

designed for a load of a minimum of 2 tons should be mounted

above the Hull Unit. The tackle may be used to facilitate the

mounting of the trunk and Hull Unit, and is also intended for use

in future service of the Hull Unit.

Heating

The sonar room should be furnished with a heating element of

1000 W, mounted close to the floor.
