PROBLEM TO BE SOLVED: To provide an internal combustion engine waste heat recovery plant capable of improving general energy efficiency of a propulsive system. SOLUTION: This internal combustion engine waste heat recovery plant of a vessel 1 having the composite propulsive system 3 of a main machine 9 and electric propulsion is characteristically furnished with a turbine 19 for generator driving to drive a generator 21, a boiler 17 to form superheated steam, a high pressure steam forming means 23 to form high pressure steam by collecting a heating value from exhaust gas of the main machine 9 and a low pressure steam forming means 25 to form low pressure steam, a superheated steam supplying line 67 to introduce the superheated steam to an inlet of the turbine 19 for generator driving, a high pressure steam line 69 to introduce the high pressure steam to an upper stage side air mixing stage of the turbine 19 for generator driving, a low pressure steam line 71 to introduce the low pressure steam to a lower stage side air mixing stage of the turbine 19 for generator driving and a control part to control to reversely decrease and increase supplying quantity of the superheated steam line 67 when high pressure steam quantity and low pressure steam quantity increases and decreases.
