Norway’s Amon Maritime is setting up an offshore shipping company to develop ammonia-fuelled platform supply vessels.

The clean shipping company, backed by Mosvolds Rederi, said the new ships could be up and running for start-up Amon Offshore by 2025.

The design has received approval in principle from classification society DNV and has preliminary flag approval from the Norwegian Maritime Authority — the world’s first such approval for an ammonia-powered ship.
