New marine engine collaboration, safety systems and key AiPs awarded

Julian Atchison June 14, 2023

A new MoU between WinGD and Mitsubishi Shipbuilding will see the deployment of WinGD’s X-DF-A ammonia-fueled engines to a range of vessels. In Norway, Wärtsilä has unveiled a safety system designed for continuous onboard monitoring of ammonia leaks, featuring a staged combustion process to deal with accidental releases. And classification society DNV has awarded AiP to two significant ammonia-fueled vessel designs: the MS NoGAPs, and Viridis Bulk Carriers’ short sea bulk carrier.

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.

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 supply chain between the Middle East & Japan takes shape

Julian Atchison May 10, 2023

Mitsui & Co., INPEX and Japanese government agency JOGMEC will partner with ADNOC to verify the emissions intensity of ammonia produced at a new project in al-Ruwais, UAE. The final methodology is likely to reflect the definition of clean ammonia currently being developed in Japan. Shipments of CCU-based ammonia have arrived in Japan & India in recent weeks from SABIC in Saudi Arabia, further highlighting the potential of Middle East supply chains.

New ammonia-powered vessel designs win AiP

Julian Atchison February 28, 2023

Three new ammonia-powered, bulk carrier designs have recently been awarded Approval in Principle. In China, SDTR Marine & SDARI’s Kamsarmax dual-fuel design received AiP from the China Classification Society. In Japan, another Kamsarmax-sized vessel developed by Sumitomo and Oshima Shipping was approved, and ClassNK has signed off on a Capemax vessel designed by MOL and Mitsui & Co., which includes an ammonia-powered main engine and hard sails to improve energy efficiency.
