RMK Marine completes keel laying of Sirius-Gasum JV’s LNG bunker tanker

Turkish shipbuilder RMK Marine on Monday (13 April) said it completed the keel laying of the LNG and bio-LNG bunker tanker Celsius.

The vessel is being built by RMK Marine for a Joint Venture between Gasum and Swedish shipping company Sirius Shipping to support cleaner energy solutions in the Nordics. 

Celsius will serve Gasum’s customers starting 2027 and will enable Gasum to fulfil its strategic ambition to increase LNG and bio-LNG availability in the Northwestern European maritime market.

“With this important milestone, construction of the 112.90-metre Celsius has officially begun,” RMK Marine said in a social media post.

“The keel laying marks steady progress in the project and underscores our continued commitment to innovation and more sustainable shipping solutions.”
