In the engine room there is the bilge emergency draining system, which operates with shunters, which allow using the sea water pumps, driven by the propulsion engines as draining pumps.
The diverters are valves that in normal position ensure the suction of sea water cooling engines from the sea outlets and sea water filters. In case of emergency activate:
The suction of the pumps, dragged by the motors, is then diverted directly into the bilge. If the need arises to use this exhaustion system, the bilge level must be checked continuously, as the engines will run out of cooling if exhaustion is complete.
When the bilge is empty, remember turning the valves back to seawater intake position, in order to avoid damaging the engines.
In case of emergency it is possible to suck the water from the bilge through the sea water pumps of each engine.
