Yanmar Delivers Dual-Fuel Tugboat Propulsion Engines

Yanmar has delivered two 6EY26DF dual-fuel commercial marine engines with the ability to use both heavy fuel oil (HFO) and liquefied natural gas (LNG) as fuels for the LNG tugboat. Mitsui O.S.K. Lines, Ltd. (MOL) will take delivery of the vessel once construction is completed in February 2019 with the tugboat expected to commence operation in April 2019.

Yanmar has also received orders for the LNG fuel tanks, buffer tanks, and gas combustion devices that make up the LNG fuel feed systems for the engines.

The MOL-owned vessel will be manufactured by Kanagawa Dockyard Co., Ltd. and operated by Nihon Tug-Boat Co., Ltd. with Osaka Gas Co., Ltd. providing the LNG fuel. This is the first time that a LNG-fueled boat has been constructed in Japan, based on the IGF Code*.

Yanmar continues to make efforts to reduce environmental burdens, develop environment-friendly clean marine engines, and provide optimum solutions to customer needs.
