Question 5066 Deck General

The correct answer is D) overboard discharge. On a COASTAL DRILLER, the bilge discharge is normally through the overboard discharge. This is because bilge water, which collects in the lowest part of the vessel, needs to be pumped out and discharged overboard to maintain the proper functioning and safety of the vessel. The overboard discharge system allows for this bilge water to be safely removed from the vessel without creating any environmental or safety hazards. The other options are incorrect because: A) a skimmer tank is used to separate oil from the bilge water, not for the actual discharge; B) sump valves control the flow of bilge water to the pump, but do not represent the final discharge point; and C) dump valves are not typically used for routine bilge discharge on a COASTAL DRILLER.
