The MAN Diesel & Turbo two-stroke B&W ME-GI engine: marine engine OEMs will need to know what IMO sulfur cap compliant fuels and systems shipowners will be using in order to be able to design and supply the right kinds of engines for the maritime industry before the new regulations come into effect in 2020.
