Wärtsilä’s 4-stroke ammonia engine is now commercially available. Meanwhile, WinGD and CMB.TECH’s plan for newbuild vessels based on WinGD’s 72-bore ammonia engine design has been underwritten in partnership with China State Shipbuilding Corporation.
For our final episode of Maritime Ammonia Insights, we asked our resident experts Sofia and Conor Fürstenberg Stott to provide their insights on the pathway forward for marine ammonia fuel. Discussion topics included challenges for overlaying alternative fuels onto the existing bunker industry, the importance of seafarers to the transition, and why we need to move beyond talking about competition between alternative fuel candidates.
Following a successful engine retrofit, FFI’s dual fuel vessel debuted at COP28 this month. Unable to run on or carry ammonia fuel due to restrictions from local authorities, FFI Chairman Andrew Forrest called for the world’s ports to catch-up to technological progress and update their regulations. FFI will also be a key part of the Pacific Northwest Hydrogen Hub (one of seven hubs awarded funding by the US DoE), and has added to its vertical integration capabilities with the opening of a new technical innovation centre in the UK.
Maersk Tankers has ordered up to ten very large ammonia carriers (VLACs) from Hyundai Samho Heavy Industries (HHI). The Korean-built vessels will have a capacity of 93,000 m3, with Maersk to make a decision to install ammonia-capable engines based on “regulatory and customer” support.
Höegh expects the first pair of ammonia-powered car carriers to be delivered late next year from China Merchants Heavy Industry at the Jiangsu Shipyard in China. This month, a new LNG/ammonia tank was installed in the first of the vessels, and MAN ES engines have arrived from Korea, with installation to take place in early December. Höegh has also announced a partnership with Yara Clean Ammonia to develop a future supply of ammonia fuel for the vessels.
NYK reports the retrofitting of the LNG-fueled tugboat Sakigake has begun in Yokohama. An ammonia-fueled engine developed by IHI Power Systems, NYK, Japan Engine Corporation and Nihon Shipyard will replace the conventional system on board, with the tug due to hit the water by 2024. NYK & Chilean copper producer CODELCO have also announced they are developing an ammonia-powered Handymax bulk carrier, aiming to develop a fleet to service the cross-Pacific copper trade.
