Requirements for insulation, heating and ventilation
The bulkheads in the sonar room should be insulated and provided with an interior wall
to the deck. The room should be equipped with heater and connected to the vessel's
ventilation system.
Heating requirements
Heating is an effective method for reducing humidity. The heater in the sonar room must
dimensioned to maintain the equipment within its environmental tolerances.
Observe the environmental specifications related to the EM 124 units.
Ventilation requirements
The sonar room should be connected to the vessel's ventilation system to ensure a supply
of cooling air. If a ventilation system is not available, install two 3” pipes from the sonar
room to a suitable fresh air location on deck.
The fresh air should enter the room as close to the floor as possible, and should be
extracted from as high as possible. A funnel shaped drip-collector must be mounted
below the vent pipes to divert moisture to the bilge. 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 must be fitted with
goosenecks or an equivalent design.
Note
If the vessel is likely to operate in tropical conditions, a suitable air conditioning system
must be installed. The air conditioning system must be able to provide an ambient
temperature that does not exceed the maximum operating temperatures of the EM 124
units that are installed in the room.
Requirements for electrical installations, cables and
communication
The electrical installations in the sonar room must meet minimum requirements to
provide suitable lights and supply power.
Light requirements
The sonar room must be equipped with suitable lighting to simplify the installation
and to aid future maintenance.
Communication requirements
The sonar room should be equipped with a telephone, an intercom system, or any other
means of oral communication between the sonar room and the bridge and/or control
room(s).
