CB&I, a subsidiary of McDermott, and Hanwha Ocean have secured Approval in Principle (AiP) for the design of an 80,000 m3 liquid hydrogen (LH2) carrier from DNV at the Gastech Exhibition & Conference in Houston. The AiP confirms that CB&I's cargo containment system meets safety standards, making international liquid hydrogen supply chains feasible. The carrier design includes a low boil-off rate of 0.05% per day, enhancing efficiency. Hanwha Ocean's expertise in gas carriers complements CB&I's storage systems. DNV, a leading classification society, emphasizes the importance of technical maturity in LH2 transportation. The collaboration between CB&I, Hanwha Ocean, and DNV aims to develop eco-friendly solutions, such as an electric propulsion system with hydrogen fuel cells. The partnership signifies global cooperation to advance the future of renewable energy. CB&I, with over 60 years of experience in LH2 storage, provides its vacuum-insulated double-wall spheres for LH2 transport. Hanwha Ocean's CTO mentions a tripartite agreement with CB&I and DNV to develop the medium-sized LH2 carrier. DNV Korea and Japan's Regional Manager highlights the joint effort to improve LH2 transportation technology. Overall, the article showcases the collaboration between industry leaders to advance sustainable energy solutions, focusing on the development of innovative concepts for liquid hydrogen transportation.
