Description

TECHNICAL FIELD [0001] The present invention relates to a bilge discharging system and a ship having the bilge discharging system.

The present invention relates to a bilge drainage system and a ship having the bilge drainage system. More particularly, the present invention relates to a bilge drainage system capable of preventing a bilge from flowing to a heat exchanger side when an emergency bilge is discharged, and a ship having the bilge drainage system.

Generally, bilge refers to water leaking through the shell or piping in ships, water contaminated with oil from decks, and water from cargoes.

If the bilge is discharged to the outside of the ship in a state where the bilge is not purified, it may cause marine pollution, and each country is regulating the bilge emissions through environmental laws individually.

On the other hand, in case of an emergency such as a fire, a collision, etc., the bilge may be discharged urgently so as to prevent further damage.

In this case, the bilge is urgently discharged via a general sea water supply passage instead of having a separate pipe, so that the bilge may flow into the space into which the seawater should flow and contaminate the space.

Particularly, when the bilge flows into the heat exchanger, there arises a problem that the contaminants contained in the bilge contaminate and break the heat exchanger.
