ABSTRACT A low-speed two-stroke diesel engine (12) is provided in the hull (22) and is connected to the propeller (16) via a line of shafting (21) for direct propulsion of the propeller. A thrust bearing (15) secured in the hull (22) and taking the axial forces of the propeller is disposed in the line (21) between the propeller (16) and the diesel engine (12) and a coupling (14) allowing axial movements of the shafting portions connected by the same is provided between the bearing (15) and the engine (12). The merchant vessel running costs are low because the direct propulsion eliminates transmission losses between the engine and the propeller, and because of the low specific fuel consumption of low-speed two-stroke diesel engines. The thrust bearing protects the engine from the considerable axial forces of the propeller occurring during ice-breaking, thus simplifying the engine design.
