In 2012 MAN Diesel & Turbo decided to expand the engine portfolio with engine designs that allow operation on fuels with low flashpoints. Since then, nine engines of the 50-bore MAN B&W engine design intended for operation on methanol have been ordered.
The orders placed are based on MAN Diesel & Turbo’s proven MELGI design concept and the engines will be delivered in 2015 from various licensees. On 17 March 2015, the first test on
methanol was completed at MAN Diesel & Turbo’s Diesel Research Centre in Copenhagen, Denmark, in the presence of classification societies, shipowners, licensees and fuel gas system
makers. This technical paper focuses on the technical data obtained from this test and the subsequent test made on a 4-cylinder engine in Japan.
