Lloyd's Register approves dual-fuel system for Trafigura gas carriers

LR conducted a comprehensive design evaluation and safety assessment to approve the designs per its regulations and international standards.

The introduction of ammonia dual-fuel systems on these vessels represents a “significant advancement” in the adoption of low-carbon fuels, extending their application beyond specialised vessels to a wider range of ship types.
Trafigura selected South Korean shipbuilder HD Hyundai Mipo in 2024 to construct four 45,000m3 MGCs.

Set to be built at HD Hyundai Mipo’s shipyard in Ulsan, South Korea, these vessels are expected to be delivered by 2028.

It is in Singapore it is happening:

Itochu orders world's first ammonia bunkering vessel - Splash247

Itochu, via its Singapore bunkering subsidiary, has signed a shipbuilding contract for the construction of a 5,000 cu m ammonia bunkering vessel with Sasaki Shipbuilding and an agreement regarding the construction of an ammonia tank plant that will be loaded onto the vessel with Izumi Steel Works. The ship will fly the flag of Singapore, the world’s top bunkering hub, where it will be based.

Several other maritime nations and industry players—including Singapore, Norway, and South Korea—have announced feasibility studies or early-stage plans for ammonia bunkering, with many ammonia-ready vessels on the global orderbook.

Amon Shipping in the news again:

Norway's Amon Bulk expands ammonia bulker scheme with three more kamsarmax...

Amon Maritime, which set up Amon Bulk earlier this year, said the vessels are aimed in part at European steelmakers facing growing pressure to cut the carbon footprint of their logistics chains.

The newbuilds will be compliant with the EU Emissions Trading System and FuelEU Maritime requirements, which the company says should help protect earnings as regulation tightens over the coming decade.

They are not alone betting on ammonia as the marine fuel for the future:

Teresa Bui, senior director of the climate campaign at Pacific Environment, commented: “The shipping industry is one of the dirtiest polluters on the planet and this announcement signals to the market that the demand for zero-emissions shipping is here.”

“Blue Ammonia” rather than “Green” in the news this time:

By converting surplus natural gas into transportable lower-carbon fuel, the concept creates new revenue streams, bolsters energy security, and diversifies the energy mix. The International Energy Agency expects blue ammonia to scale rapidly for power generation and maritime transport to meet emissions targets.

PS: Intended for the GoM maybe?_
