Exmar has named its third and fourth dual-fuel ammonia-powered oceangoing vessels, Adinkerke and Aalter, at a naming ceremony held on 25 August.

The two vessels join sister ships Antwerpen and Arlon, which are already part of the Belgian company’s fleet. Adinkerke and Aalter will sail under the Belgian flag and are to be placed under the management of Exmar Ship Management upon delivery.

The naming ceremony was attended by representatives from the shipyard, Exmar teams and the vessels’ godmothers, who performed the traditional blessing of the vessels.

As previously reported, Antwerpen was the first vessel in the series of four ammonia dual-fuel midsize gas carriers, each named after a Belgian city. Described as the world's first oceangoing vessel equipped with a dual-fuel ammonia engine, it is capable of carrying up to 46,000 cbm of ammonia or LPG. The ship's first commercial voyage using ammonia as fuel ran from China to India.

Exmar took delivery of Arlon, its second dual-fuel ammonia mid-sized gas carrier, from HD Hyundai Heavy Industries shipyard in South Korea last month. Also with a carrying capacity of up to 46,000 cbm, the ship will be owned by Exmar France.

Exmar Group specialises in floating maritime solutions for the transport, transformation, and storage of gas and liquid hydrocarbons, operating a fleet ranging from very large gas carriers (VLGCs) to pressurised vessels, as well as floating LNG production, storage, and regasification units.
