Abstract
A system for draining a cooling system of a power generation system on a marine vessel includes a pump in fluid communication with the cooling system, the pump actively removing cooling water from the cooling system. An outlet drain discharges the cooling water. A controller starts the pump in response to an operator command to stop a prime mover of the marine power generation system and/or a speed of the prime mover being below a threshold speed. In one example, a temperature sensor determines a temperature of the cooling water in the cooling system, and the controller stops the pump in response to the temperature of the cooling water exceeding a threshold temperature. In another example, a sensor determines a pressure and/or a level of the cooling water in the cooling system, and the controller stops the pump in response to the pressure and/or the level of the cooling water dropping below a threshold pressure or a threshold level, respectively.
