ABS issues advice on strengthening independent Type C tanks for alternative fuels

Classification society ABS has developed Guidance Notes on Strength Assessment of Independent Type C Tanks which provides procedures for determining design loads on the Type C tanks and performing the strength evaluation of the tank and supporting structures.

ABS notes that alternative fuels will play an important role in the decarbonization of shipping, increasing the popularity of Type C tank designs for vessels.

Independent Type C liquefied gas cargo tanks, used in gas carriers, bunkers, and barges, can be used to carry LNG, LPG, ammonia, and hydrogen in a liquid state and are seen as a promising solution for transporting these gases.

Type C gas fuel tanks, such as vacuum-insulated Type C tanks with double shells, allow for the same flexibility in fuel options when powering vessels and is the most popular design for a gas fuel containment system.

The new Guidance Notes on Strength Assessment of Independent Type C Tanks can be downloaded from the ABS website.
