ABS greenlights Tritec Marine's 20,000 cbm LNG bunker vessel design

Tritec Marine, a subsidiary of Northern Marine Group and Stena Group, has received approval in principle (AiP) from classification society American Bureau of Shipping (ABS) for its Safe Bunker 20,000 cubic meter (cbm) LNG bunker vessel design.

The design was developed by Tritec Marine in partnership with cryogenic liquid cargo containment systems provider Bluesol under the collaboration agreement from 2024.

The agreement entailed tailoring Tritec Marine’s Safe Bunker LNG bunker vessels by including Bluesol’s proprietary Bastion B aluminum alloy LNG (Type B) cargo containment system.

As explained, Bluesoul’s IMO B tank is a prismatic tank equipped with anti-sloshing bulkheads. Using aluminum alloy 5083-O, this B tank is 30% lighter than the traditional stainless steel and nickel tanks, easy to scale up, and allows for increased cargo carrying capacity at comparable drafts. The tank is covered by oxide film, does not require coating, is easier to maintain, and can be used to transport LNG, ammonia, and liquid hydrogen.

With the ABS’ approval, the companies are now in discussions with parties interested in Safe Bunker technology licenses for construction.
