Ship's Seepage is a term used to describe the water that accumulates in the BILGE of a ship. The BILGE is the lowest compartment of a ship, located at the bottom of the hull, and is where any water that enters the ship collects. Ship's Seepage is caused by a variety of factors, including leaks, condensation, and rainwater. It is important to regularly check and pump out the BILGE to prevent the accumulation of water, which can lead to instability and other problems.
