Sumitomo Corporation and Oshima Shipbuilding to develop ammonia-fuelled bulker

29 Dec 2021

Sumitomo Corporation on Monday (27 December) said it will launch a full-scale project to design and develop an ammonia-fuelled dry bulk carrier jointly with Oshima Shipbuilding Co., Ltd.

In 2018, the International Maritime Organization (IMO) adopted a strategy to reduce greenhouse gas (GHG) emissions from international shipping. In this strategy, the IMO upholds the target of improving the average fuel efficiency of ships used for international shipping by 40% relative to the 2008 level by 2030, and of halving the total GHG emissions from the ships by 2050.

In response, companies in the maritime industry are required to replace the fuels for their ships with ammonia, hydrogen and other substitutes with low environmental impact, and to introduce the equipment that will help them reduce their GHG emissions.

As ammonia can be liquefied more easily than hydrogen, the substance is attracting much attention as a substitute fuel for ocean-going ships that navigate a long distance at one time.

Oshima Shipbuilding has been manufacturing and selling dry bulk carriers jointly with Sumitomo Corporation since 1973. The shipbuilder has a large production capacity backed by its long-accumulated technologies and expertise.

Sumitomo Corporation, jointly with this shipbuilder, will work on the design and development of an ammonia-fuelled dry bulk carrier ahead of the world toward completing the ship within 2025.

Sumitomo Corporation will design and develop the bulk carrier, improve the navigation environment, and ensure the supply of ammonia as fuel, in cooperation with Oshima Shipbuilding and other external partners as well as with the involvement of the internal cross-organizational project team for ammonia, which was launched within Sumitomo Corporation this July.

After the completion of the bulk carrier, Sumitomo Corporation will own and operate it, thereby helping users of the ship’s transportation service to reduce their GHG emissions across their supply chains.

Since this March, jointly with external partners, Sumitomo Corporation has been examining the launch of an ammonia supply business to fuel ships in Singapore.

In addition to building an ammonia supply chain, the company is in discussions with the Singaporean government for the formulation of operation guidelines and the establishment of the necessary regulations.

Specifications of the bulk carrier to be designed and developed are as follows:

Overall length 229.0m
Beam 32.26m
Depth 19.98m
Designed draft 12.20m
Full load draft 14.47m
Deadweight 80,000 to 81,000 mt
Speed 14.3 knots
