Deltamarin and GTT have received an Approval in Principle (AiP) from ClassNK for their LNG-fuelled 12,500cbm Very Large Crude Carrier (VLCC) design. The design retains the same cargo capacity as a standard VLCC owing to its use of membrane-type LNG fuel tanks in the design.

The AiP was awarded by ClassNK on 1 March 2023 for the design.

Deltamarin, GTT and ClassNK have been collaborating on the development of an LNG-fueled energy-efficient Very Large Crude Carrier. The vessel will meet current and future environmental targets by deploying GTT Membrane-type LNG tanks with LNG fuel stored at atmospheric pressure. The containment technology itself represents a well-studied and pre-approved solution, Deltamarin stressed.
