Bureau Veritas has granted approval in principle (AiP) for a large LH2 carrier and associated membrane tank design.

A joint development project undertaken by GTT, TotalEnergies, vessel designer LMG Marine, and Bureau Veritas (BV) has led to the design of a cryogenic membrane containment system for liquefied hydrogen (LH2) and the preliminary design of a 150,000m3 LH2 carrier.

The vessel has a single shaft and electric propulsion. The power plant is based on a mix of dual fuel H2 genset and fuel cells, primary fuel being hydrogen. As H2 is an extremely low-density product, the conventional hulls shapes found on common gas tankers were not suitable, so a specific hull shape has been developed to ensure proper propeller immersion.
