MCR (Maximum Continuous Rating) is determined from rated powerģ. One of the most important factors for selection of an engine i.e. Rated power includes the loads which act on the engine due to the auxiliary system running from the engine power. Rated Power: It is the continuous effective power provided by the manufacturer of the engine for a desired or rated RPM of the crankshaft. This method is preferred if non-direct propulsion unit is present (i.e. Engine mean indicated pressure measurement – using the in-cylinder pressure transducer.Speed and torque measurement – using the propulsion shaft arrangement.Effective power is determined by an engine’s size and by its mechanical efficiency.Įffective power estimation can be done by two methods: It can be said that this is the developed power by the engine available to the flywheel. at crankshaft flange of the engine which connects it with the flywheel and rest of the intermediate shaft. Effective Power: The Power available at the output side of the engine i.e. Representation Imageįollowing is the list of “Power” Terminologies used for a Marine Propulsion Engine on board ship:ġ. There are several terminologies for “Power” rating used for Marine Propulsion Engine and each of these gives different value of engine performance under various parameters and situations. The overall operation of the ship is highly dependent on the performance of its main propulsion engine, measured in terms of its power rating. The Wartsila Sulzer RT-Flex 96 C is the world biggest and most powerful engine ever made with an output of approx 80000 KW or 108900 BHP. The best thing about being a marine engineer on a ship is controlling the most powerful thing in the world ever created by man- the ship’s main propulsion engine.
