AP Møller-Maersk’s recently ordered carbon-neutral methanol-fuelled box ship will have two HiMSEN 6H32F-LM generator engines supplied by Hyundai Heavy Industries Engine Machinery Division (HHI-EMD)
The contract represents the first methanol-burning dual-fuel engine order for the South Korea enginebuilder. It said it would supply methanol-fuelled generator engines, each rated 3,000 kW at 720 rpm, for the world’s first methanol-powered container ship that will be built by Hyundai Mipo Dockyard for delivery in 2023. The HiMSEN engines will be delivered to the shipyard in December 2022.
The box ship’s main engine will be a dual-fuel, two-stroke MAN 6G50-LGIM developed by MAN Energy Solutions and HHI-EMD.
With six to nine cylinders, the power range of the four-stroke HiMSEN H32DF-LM is 3,000 to 4,500 kW, with the capability of burning methanol in the diesel cycle without knocking or misfiring while producing negligible fuel slip.
HHI-EMD expects methanol will be one of the alternative fuels adopted by shipping. The engine and technology portfolio of HiMSEN is expanding to handle alternative fuels such as methanol, ammonia and LPG.
In May, Korea Shipbuilding & Offshore Engineering and Hyundai Heavy Industries were granted an approval in principle for a low-flashpoint fuel injection system by Korean Register.
This newly developed technology can use LPG with a low-flashpoint of -104°C as well as other fuels such as methanol and ammonia, having low-flashpoint fuels in a single fuel injection system.
