To provide a waste heat recovery system for a vessel capable of efficiently recovering waste heat regardless of a flow volume of excess steam. Provided is a waste heat recovery system for a vessel for supplying, to a steam utilization device, steam generated by a steam generator, using waste heat from a main machine as a heat source. With respect to the waste heat recovery system, a plurality of expansion machines are connected in parallel to one another, and excess steam without being supplied to the steam utilization device is supplied individually to the expansion machines by the opening/closing of gate valves arranged in the respective expansion machines respectively. |
