Until the end of 2004 there was still one market for ocean-going cargo ships to which the two-stroke engine had not yet been introduced: i.e. the LNG market. This market has so far been dominated by steam turbines, but the first orders for two-stroke diesel engines were given at the end of 2004. Today, 16 ME engines to LNG carriers have been ordered for eight LNG carriers, which are to be built in Korea, Ref. [1].
