1.3 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 3.5 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.
Insulation
The bulkhead must be insulated and plated down to the floor. The
insulation should equal a minimum of 50 mm of rock-wool.
