Ship owner Exmar on Monday (5 January) said it successfully completed its largest ship-to-ship (STS) transfer of ammonia to date in Oman. Its vessel KORTRIJK,  ( IMO 9687514, MMSI 205706000-  sailing under the flag of Belgium.) a Midsize Gas Carrier with a capacity of 38,500 cbm, safely discharged full cargo of ammonia, in collaboration with Trammo, Inc. at the port of Sohar in Oman The vessel arrived at the port of Ras Al-Khair Anch., Saudi Arabia according to Vessel Finder

The milestone operation

“This milestone operation is the perfect example of the professionalism of our well-trained crew and their adherence to the highest safety and operational protocols throughout the transfer,” the company said in a social media post. Having over 40 years of experience in handling and transporting ammonia, we continue to build on our expertise in this type of cargo, positioning us strongly as ammonia is increasingly expected to play a key role as a fuel for marine transport.”

Currently, Exmar is expanding its fleet with four 46,000m³ MGCs, equipped with ammonia dual-fuel engines, preparing for a future of safe and low-carbon shipping.

Third dual-fuel LPG ship

On the other hand their third dual-fuel LPG-powered ship (S1085) with a capacity of 41,000m³ was successfully launched in CIMC, China. Shortly after, H8390, our second 46,000m³ MGC, equipped with dual-fuel ammonia engines followed at HD Hyundai, Ulsan. We look forward to welcoming these new dual-fuel vessels into our fleet in 2026!

Why ship-to-ship transfers matter?

Ammonia is hazardous and toxic, which means strict safety protocols are required for its use and handling as a marine fuel, particularly during bunkering and storage.

STS  ( Ship - to Ship ) transfers can be used to replicate the key steps involved in ammonia bunkering, as both operations require specialised equipment, robust containment and strict handling procedures to minimise the risk of leaks and exposure to ammonia during fuel transfer between vessels.

Several ammonia STS pilots took place last year.

Singapore’s Global Centre for Maritime Decarbonisation carried out an ammonia transfer trial in the Australian port of Dampier. Japanese shipping company NYK Line completed its first STS ammonia transfer of about 23,000 mt of liquefied ammonia off the coast of Ceuta in Spain.Commodity trader Trafigura and shipowner Purus also completed an STS operation near Ceuta, transferring about 6,000 mt of ammonia cargo.
