HHI-EMD to supply new four-stroke engine sets for 13,000-TEU box ships

Meanwhile, HHI-EMD said the new HiMSEN H21C, H32C line-up was developed by HHI-EMD to have improved engine output, performance and maintenance convenience.

More than 14,000 HiMSEN engine sets have been exported globally to date, and HHI-EMD is focusing on developing engines that can burn future fuels such as methanol and ammonia engines.

HHI-EMD secured an order to supply two HiMSEN 6H32F-LM generator engines for AP Møller-Maersk’s methanol-fuelled feeder ship – which aims to operate on carbon-neutral fuel when it goes into operation in 2023.

These were the first methanol-burning dual-fuel, four-stroke engines ordered from the South Korea enginebuilder. The methanol-fuelled generator engines, each rated 3,000 kW at 720 rpm, will be delivered to Hyundai Mipo Dockyard December 2022.

With six to nine cylinders, the power range of the four-stroke HiMSEN H32DF-LM is from 3,000 kW to 4,500 kW, with the capability of burning methanol in the Diesel cycle without knocking or misfiring while producing negligible fuel slip.

As for the ship’s main propulsion, it will be supplied by a methanol dual-fuel, two-stroke MAN 6G50-LGIM developed by MAN Energy Solutions and HHI-EMD. The ship’s dual-engine technology enables it to sail on either methanol, biofuels or very low sulphur fuel oil.

The prime movers for a series of eight 16,200-TEU container ships for AP Møller-Maersk will also be MAN Energy Solutions’ dual-fuel LGIM engine technology.

As of February 2022, HHI-EMD had delivered 14 methanol dual-fuel two-stroke engines and accumulated orders for 17 others.
