Turkiye’s RMK Marine has officially begun construction of an LNG bunkering vessel for a joint venture between the Finnish state-owned energy firm Gasum and the Swedish shipping firm Sirius.
According to social media posts by RMK and Sirius, the steel-cutting ceremony for the vessel, which will be named Celsius, was held on Wednesday.
With this steel-cutting ceremony, the project is “well underway” and will be able to service its customers in the summer of 2027, Sirius said.
“Celsius will be different from other LNG bunker vessels since it will have a gas combustion unit on board to assist with cool-downs and gassing up. A unique service that will be offered to vessels either carrying LNG or powered by LNG,” the company said.
Last year, Gasum and Sirius announced that they had ordered one LNG bunkering vessel with a capacity of 7,500 cbm from the Turkish shipbuilder.
The vessel will feature a hybrid battery.
It will be 112.9 meters long and 19 meters wide, with a draft of 6 meters.
Sirius and Gasum have a long history together, as Gasum has been the charterer of the bunker vessel Coralius since 2017, and Sirius has been managing Gasum’s bunkering vessel Seagas since 2012.
