MOL Signs Deal for Construction of LNG-fuelled Tugboat

Mitsui O.S.K. Lines, Ltd. announced last week that it has signed a deal for the construction of an LNG-fuelled tugboat with Kanagawa Dockyard Co., Ltd.

The construction is slated to start in February 2018 and complete in February 2019. And launching is scheduled for April of the same year.

This marks MOL's first ownership of a tugboat powered by LNG-fuelled engines - produced by Yanmar Co. Ltd. - and it will be the first LNG-fuelled tugboat in Japan conforming to the IGF code. It is also Japan's first LNG-fuelled tugboat with the LNG fuel tank mounted on the exposed deck at the stern of the ship. This enhances convenience in bunkering, maintenance, and inspection.

The ship will be operated by Nihon Tug-Boat Co., Ltd and it will be deployed in Osaka Bay in April 2019. LNG fuel will be supplied by Osaka Gas Co., Ltd. using a truck-to-ship system. MOL and Osaka Gas will establish an LNG fuel supply system for vessels, which will be the first in Osaka Bay and cooperate in the measures of LNG fuel supply development project conducted by Port and Harbour Bureau of Osaka Prefectural Government at the Sakai-senboku Port.

MOL will move ahead with research on practical use of an LNG fuel supply system with a detachable, portable LNG fuel tank, by adapting this design to the tugboat.

MOL has conducted various researches related to LNG fuel, such as a joint study of an LNG-fuelled Capsize bulker, an Approval In Principle (AIP) for the future design of a series of LNG-powered 20,000 TEU-class containerships, and an AIP for the design of an LNG-powered coal carrier. MOL will also leverage those achievements, including the newest effort of LNG-fuelled tugboat, in the development and operation of various types of LNG-fuelled ships, like the environment-friendly ISHIN-II ferry, a future initiative in the "ISHIN NEXT - MOL SMART SHIP PROJECT" and other cargo ships in the future, and takes an ongoing proactive approach to promotion of LNG fuel as a way to reduce the environmental impact of vessel operations.
