Accepted Answer

Option A: The two-speed main sea water circulating pump can be used for this purpose.. In many marine steam plant designs, the main circulating pump is a high-capacity, two-speed unit. The suction side is often cross-connected to the bilge manifold, allowing the pump to act as an emergency bilge pump to handle large volumes of water during a major flooding event in the machinery space.
