Maritime updates: modeling engine room fuel leaks, testing a new fuel supply system

Julian Atchison June 04, 2023

ABS has used computational fluid dynamics to model ammonia dispersion patterns in a ship’s engine room, with the aim of producing a fast, real-time response system for ammonia leaks. In Japan, a fuel supply system for large-scale, low-speed, two-stroke marine engines is undergoing final verification testing. Mitsubishi Shipbuilding aims to become a key technology provider of such systems, and in the ammonia maritime fuel space.

Safety and the marine ammonia engine

Conor Furstenberg Stott June 04, 2023

As part of our Maritime Ammonia Insights webinar series, we explored the safety learnings gained so far during the development of maritime ammonia fueled engines, as well as existing best practices for safe ammonia handling. John Mott (ASTI), Kaj Portin and Laura Sariola (both Wärtsilä) were joined in conversation by Conor Furstenberg Stott.

Project Ra: 1.6 million tonnes per year renewable ammonia near Port Said

Julian Atchison May 30, 2023

Germany-based DAI Infrastruktur will develop Project Ra - 1.6 million tonnes per year of ammonia to be produced near Port Said on Egypt’s Mediterranean coast. DAI has already secured two offtake deals for the project, totalling one million tonnes of ammonia per year from 2028.

IHI, NYK Line report successful marine engine testing in Japan

Julian Atchison May 23, 2023

Successful testing has been completed at IHI’s facilities in Ota, Japan. A four-stroke marine engine - fully integrated with exhaust gas aftertreatment and fuel supply systems - produced stable operations running on up to 80% ammonia fuel. Emissions of dinitrogen monoxide (N₂O) and ammonia slip were reported as “virtually zero”.

Ammonia fuel could begin powering Australia - Asia green maritime corridor from 2028

Julian Atchison May 22, 2023

Ammonia-powered vessels could be deployed on the iron ore trade routes between West Australia and East Asia from 2028, a new consortium study suggests. More than 20 vessels could be deployed on these routes by 2030, and over 360 by 2050. While ammonia fuel supply from Australia is unlikely to be a concern, validating the safety case for ammonia fuel, policy support to close the cost gap & industry-wide collaboration must all be established in time for deployment.

North Ammonia to supply ammonia fuel for Höegh Autoliners’ fleet

Julian Atchison May 22, 2023

Norway-based North Ammonia will supply at least 100,000 tonnes per year of ammonia fuel to Höegh Autoliners from 2030, powering their future fleet of Aurora class car carriers. Grid-based electrolysis will feed production of ammonia in Eydehavn on Norway’s south coast, with bunkering to take place somewhere in the Amsterdam-Rotterdam Antwerp area. In more maritime ammonia news out of Norway this week, Skarv Shipping will receive government funding to develop cargo vessels featuring ammonia-powered, four-stroke engines.

Indian government releases Green Port Guidelines

Julian Atchison May 22, 2023

New guidelines for Indian ports mandate the use of renewable energy in port operations, as well as the development of storage, handling and bunkering capabilities for future maritime fuels. All of India’s thirteen major ports must have ammonia bunkering & refueling facilities established by 2035, as well as making efforts to retrofit port crafts to run on future fuels.

Ammonia-powered cruising on the Baltic Sea

Sofia Furstenberg Stott May 10, 2023

The CAMPFIRE consortium is exploring the feasibility of ammonia-powered cruise liners on the Baltic Sea. Project partners Rostock Port, Yara, DNV and Carnival Maritime discussed progress to date at a recent Maritime Ammonia Insights webinar, including promising logistics, infrastructure & safety findings.

Key shipping stakeholders see a multi-fuel future: new survey results

Julian Atchison May 08, 2023

A recent survey reveals how shipping industry leaders see the maritime fuel transition progressing. With conventional ship engines set to remain the preferred technology until at least 2050, almost all the survey respondents saw their fleets running on a mix of fuels by that date. Although methanol & ammonia are likely to be adopted at scale, respondents do not currently see any of the new fuels emerging as an industry standard, with key choices ahead for shipping companies, fuel producers, bunker providers and industry regulators.

Webinar

Safety and the marine ammonia engine

Julian Atchison

Explore the critical topic of engine room safety, and what design considerations would be needed on a future, ammonia-fueled vessel. What learnings can we apply from running prototype engines? What lessons can be learned from current ammonia-handling industries like refrigeration? And what training will be needed to build confidence in seafarers?
