The long history of the most popular S.E.M.T. Pielstick medium speed diesel engine started in 1963 with the launching of the 400-mm bore PC2.2 rated at 500 hp/cyl (368 kW/cyl) at 500/520 rpm. Since that time, 3500 engines have been produced, with a major part for ship propulsion, in different versions with power ratings increasing over the years. The latest development step allowed to reach with the PC2.6B a power of 750 kW/cyl, which means that the power has been doubled since the origin. A similar step by step development has been used for the 280 mm bore PA6 engine, which has been recently focused on a 8,1 MW engine with low specific weight (5kg/kW) for high speed ferries and navies applications. As those latest developments had to cope with constraints linked to the environment protection, new systems are being introduced to reach as much as 75 % NOx reduction. The step by step development strategy allows to incorporate in each step the experience of previous versions which ensures, besides minimsed risks for the engine designer, a maximised safety guarantee to the end user. This has been largely demonstrated by service experience results of medium-speed S.E.M.T. Pielstick engines, used for ship propulsion and manufactured by Japanese licensees.
