15-3.4.2 Bilge System. The bilge system, in the voids, collects and removes equipment waste from the barge and
keeps the bilges dry. See Figure 15-5.
A bilge pump transfers liquid containing oil to the sludge tank. This oily liquid includes bilge water from the
voids, waste lubricating oil from three diesel generators (two ship service generators and one ship auxiliary generator) in
void 4 and waste lubricating oil from two ROWPU HP pump diesel engines in ROWPU space. Bilge water from a void is
pumped to the sludge tank using a portable hose with foot valve to suck up the bilge water. Waste lubricating oil is
pumped to the sludge tank from the generator diesel engine crankcase after a hose is connected between the generator
crankcase drain valve (BD1 6, BD1 7 or BD1 8) and a void 4 suction valve (BD2 or BD10). Waste lubricating oil is
pumped to the sludge tank from the HP pump diesel engine crankcase drain valves (BD12 or BD13) and valve (BD19)
located between the high pressure pumps.
