SEMT Pielstick was a French company that designed and built large diesel engines. Its full name was (Company of Thermal Machines Studies). Founded in 1948, SEMT was bought by MAN Diesel in 2006 During its existence as an independent company, SEMT manufactured engines for locomotives, naval vessels, power plants, and merchant ships. Its customers included France, the United States, Russia, India and other countries. History SEMT. was created in 1946 by France's ministry for industrial production by combining five national companies: (Saint-Nazaire), (La Courneuve) (Le Havre) (Nantes) (Denain) The aim of the new company was to develop new engines in France that could be licensed internationally. In 1948, the first licenses were supplied to licensed engine building companies worldwide. In 1951, after its relocation at La Courneuve, the was equipped with the first test beds. The equipment, which enabled the company to speed up the development of a new range of engines, was later transferred to Saint-Denis and thesubsequently to Saint-Nazaire. In 1976, Alsthom-Atlantique was the flagship of French industry. The conglomerate became the majority, which also owns the Saint-Nazaire mechanical facility and a factory at Jouet-sur-l’Aubois, was renamed S.E.M.T. Pielstick after the company's founder, Gustav Pielstick. In 2006, MAN purchased the shares belonging to MTU to become the sole shareholder of SEMT.

Licensees SEMT has eight licensees that produce their engines: Fairbanks Morse Engine – United States Doosan Heavy Industries & Construction – South Korea Shaanxi Diesel Heavy Industry – China Hudong Heavy Machinery – China JFE – Japan Diesel United – Japan Kawasaki Heavy Industries – Japan Niigata Power Systems – Japan Engine lines PC engine line In 1951, SEMT developed the first PC1 engine. In 1953, the PC1 was modified to be powered by heavy fuel oil. The first unit to go into series production was a six-cylinder, in-line engine (6 PC1 L) for the electricity generating plant of Bamako, Mali. With a bore of 400 mm, the engine developed 180 kW per cylinder. Its first marine application for the PC1was in 1955, aboard the French Navy ship Borée (two engines). Later in the 1960s, SEMT launched the PC2 engine line. Though it kept the same 400 mm bore, power output was increased to 310 kW per cylinder – an
