Ventilation

The sonar room should preferably be connected to the ship’s

ventilation system. If this is not possible, two 3-inch vent pipes

must be laid from the sonar room to free air on deck. The air

inlet should be close to the floor, while the outlet should be

placed as high as possible. Funnels should be mounted below

the vent pipes to collect condensed water.

To ensure the best possible ventilation, the outlet pipe should

run at least 4 meters higher than the inlet pipe. To keep rain and

water splash out, the pipes should be fitted with goosenecks or

cowls.

Cable pipes

If the cable between the wheelhouse and the sonar room passes

through hatches or places where it can be damaged, it should be

run through pipes (2” pipes are recommended).

Air vent pipe

An air vent pipe with a minimum of 10 mm internal diameter

must be fitted to the air bleeding cock on the Hull Unit. The

pipe should be laid with continuous rise to free air on deck or

out through the ship s side.

Bilge pump

The sonar room should be connected to the ship’s main bilge

pump system. If this is not possible, a separate bilge pump for

the sonar room must be installed.

Lighting

To simplify the installation and future maintenance, the sonar

room should be equipped with suitable lighting.

Docking

Make sure that there is ample space below the keel for mounting

the hull system, when docking the vessel.

To facilitate future docking, mark the position of the trunk as

indicated in figure 1.

Flooring

When the installation is completed, the sonar room should be

suitably floored.
