Hyundai Heavy Industries Engine & Machinery Division (HHI-EMD) will supply six medium-speed engines with selective catalytic converter (SCR) units for Maersk Supply Service’s new wind turbine installation vessel (WTIV)
Being built by Singapore shipyard Sembcorp Marine, the WTIV will be completed in 2025 and delivered to Maersk, which has been awarded a firm contract with Empire Offshore Wind, a joint venture between Equinor and BP, for the installation of US offshore windfarms Empire 1 and 2. For the transport and logistics, Maersk Supply Service has partnered with Kirby Offshore Wind, a subsidiary of Kirby Corp, one of the largest operators of offshore barges and towing vessels in the United States. Kirby will provide the feeder barge spread in compliance with the Jones Act.
HHI-EMD reported it will supply six sets of four-stroke HiMSEN /40 engines and SCRs for delivery to Sembcorp Marine in September 2023. These nine-cylinder, in-line engines, each rated at 4,500 KW at 720 rpm, are Tier III compliant when fitted with SCR technology. At 100% load, the 300-mm bore engine has a specific fuel oil consumption of 179 g/kWh.
HHI-EMD said it plans to strengthen relations with customers to enhance its sales competitiveness in “Singapore and southeast Asia and focus on the sale with new technology products such as the engine for alternative fuels,” in a social media post.
While Maersk Supply Service did not reveal the use of alternative fuels in its new WTIV, parent AP Møller-Maersk has already taken a leap forward in specifying methanol dual-fuel engines for a 2,100-TEU feeder vessel and a series of 16,200-TEU container ships.
Maersk Supply Service and Kirby Offshore Wind are “looking into making it possible for the WTIV, tugs and barges to operate on climate-neutral fuels,” said Maersk Supply Service in a press statement.
AP Møller-Maersk’s methanol-fuelled feeder ship – which aims to operate on carbon-neutral fuel when it goes into operation in 2023 – will have two HiMSEN 6H32F-LM generator engines supplied by HHI-EMD.
These are 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 the Hyundai Mipo Dockyard in 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 the series of eight 16,200-TEU container ships 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.
