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.

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?

Maritime developments: on-water cracking, AiPs and Singapore bunker study releases first results

Julian Atchison May 05, 2023

In maritime ammonia updates this week:

  • In Europe, government funding will support the development of an ammonia cracking system that can be installed on existing LNG vessels (Norway), and the establishment of a floating production and storage facility connected to an offshore wind farm (Netherlands).
  • Two AiPs have been granted: one for Korea’s first ammonia FSRU vessel, the other for a bunkering tanker in Singapore.
  • H2Carrier and Trelleborg will develop a ship-to-ship ammonia transfer system.
  • And GCMD has unveiled the results of their Singaporean ammonia bunker study. All risks identified for conducting pilot projects were found to be low or mitigable, with work towards those pilots to continue.

Ammonia bunkering at the Port of Savannah

Julian Atchison April 11, 2023

A high-profile consortium will conduct a joint study exploring ammonia bunkering at the Port of Savannah in Georgia, USA. The consortium aims to establish a comprehensive supply chain to allow ship-to-ship ammonia bunkering in Savannah, and the study scope includes design of an Ammonia Bunkering Articulated Tug-Barge (AB-ATB) vessel.

NoGAPS vessel project enters next phase

Julian Atchison April 03, 2023

The second phase of the NoGAPS project is well underway. Led by the Maersk Mc-Kinney Møller Center for Zero Carbon Shipping, a detailed plan for the design, operation and business case for the future MS NoGAPS vessel will be developed. Construction and delivery is expected in 2024-25. Also in Scandinavia, Viridis Bulk Carriers has been awarded AiP from Bureau Veritas for its ammonia-fueled, short-sea, bulk carrier design.

Retrofitting vessels for ammonia fuel: new technical study from Grieg Star

Julian Atchison March 21, 2023

Grieg Star and a series of high-profile maritime consortium partners have assessed the full feasibility for retrofitting a Grieg Star L-Class vessel to run on ammonia fuel. The study concludes that technical & regulatory challenges will not be showstoppers in the transition. A combination of high investment costs, uncertainty over ammonia fuel availability & pricing and slow market development remain the biggest barriers, presenting significant risks for first movers.
