Question 6General Subjects - Assistant Engineer

The correct answer is B) The means by which the machinery space bilge is pumped out by a pump normally used as a bilge pump but independent of any bilge manifolds or automatic bilge suction valves. This is correct because independent bilge suction refers to a dedicated bilge pump that can operate independently of the main bilge system. It provides a redundant means of dewatering the machinery space bilge in case the main bilge system fails or is unavailable. Regulations require vessels to have this independent bilge suction capability to ensure proper dewatering and prevent flooding. The other options are incorrect because they do not accurately describe the definition of independent bilge suction. Option A refers to a pump not normally used as a bilge pump, option C describes a cargo hold bilge rather than a machinery space bilge, and option D also refers to a pump not normally used as a bilge pump.
