In Japan, Mitsui E&S Machinery, a long-term MAN Energy Solutions licensee has won a contract to supply the individual MAN B&W 6G50ME-LGIM (Liquid Gas Injection Methanol) engine for a 65 700 dwt bulk carrier slated for construction at Tsuneishi Shipbuilding Co., Ltd. The vessel represents the latest methanol-fuelled engine ordered by the bulk-carrier segment in recent weeks.

Part of Mitsui E&S Holdings, Mitsui E&S Machinery machinery manufactures marine and stationary diesel engines and marine equipment.
Customers are increasingly interested in next-generation fuels, and methanol is one of the promising fuels. We have a track record of manufacturing dual-fuel engines such as LNG-fired engines, and in 2015 delivered the world’s first methanol engine as the main engine for a methanol carrier. Taking advantage of this adoption for bulk carriers, we will continue to meet the various needs of our customers, provide engines that are environmentally friendly and economical, and contribute to the realization of a decarbonized society, said Ichiro Tanaka, President and Representative Director of Mitsui E&S Machinery.
Based in Fukuyama, Hiroshima, Tsuneishi Shipbuilding is the anchor company of the Tsuneishi Group, which conducts business mainly within the shipbuilding industry and maritime transport.
With manufacturing bases in Japan, the Philippines, and China, the company builds bulk carriers, container carriers, and tankers.
For Tsuneishi Shipbuilding, which is striving to build methanol-fuelled ships with the aim of becoming a front-runner in next-generation-fuelled ships, securing a high-value-added engine through this contract is an extremely important step. We will continue to focus on technological innovation together with engine manufacturers in order to provide our customers with zero-emission ships that are both environmentally friendly and economical, said Sachio Okumura, Representative Director and President & Executive Officer of Tsuneishi Shipbuilding.
Proven dual-fuel operations
MAN Energy Solutions developed the ME-LGIM dual-fuel engine for operation on methanol, as well as conventional fuel.
The engine is based on the company’s proven ME-series, with its approximately 8 500 engines in service, and works according to the Diesel principle.
When operating on green methanol, the engine offers carbon-neutral propulsion for large merchant-marine vessels.
In a market that has seen a rapidly increasing demand for decarbonized transport from its major players, the interest in methanol as a fuel has surged and – at this moment in time – represents more than 30 percent of all our current, open pipeline projects across a broad range of vessel segments. As such, seeing bulk carriers now also entering this fuel segment is completely in line with our expectations and these newbuilds will benefit greatly from the option to operate either on methanol or conventional fuel with equally high fuel efficiency, Bjarne Foldager, SVP, and Head of Low-Speed, MAN Energy Solutions.
As a fuel, methanol can be carbon-neutral when produced from renewable energy sources and biogenic carbon dioxide (CO2).
The production capacity of such green methanol is currently increasing significantly; it is also liquid at ambient conditions, which simplifies tank design and minimizes costs.
Methanol carriers have already operated at sea for many years using the engine, and, as such, the ME-LGIM has a proven track record offering great reliability and high fuel efficiency.
MAN Energy Solutions reports that its methanol engine requires a fuel-supply pressure of just 13 bar and that a number of manufacturers already offer such fuel-supply systems today.
With more than 20 engines installed in vessels already on the water and in excess of 200 000 operational hours on methanol since the first such engine entered service in 2016, provides an already proven and mature technology. In adopting these low-emission engines, Tsuneishi Shipbuilding once again demonstrates its commitment to providing advanced solutions for the benefit of both vessel owners and the environment, said Peter Quaade, Head of Dual-Fuel Engine Group – Two-Stroke Operations – MAN Energy Solutions.
