Innovative Liquid Hydrogen Carrier Design Approved by DNV

CB&I and Hanwha Ocean Collaborate on Hydrogen Shipping Solutions

In a significant advancement for the maritime shipping industry, CB&I, a subsidiary of McDermott, and Hanwha Ocean, a renowned shipbuilder, have secured Approval in Principle (AiP) for an innovative cargo containment system designed for liquid hydrogen carriers. This milestone was announced at a prominent exhibition where industry leaders gather to discuss the future of energy.

Details of the Approval in Principle

The AiP from DNV, a leading classification society in shipping, verifies that the design satisfies stringent safety standards, including international guidelines for transporting liquefied gases. The design incorporates advanced safety protocols to ensure that the carrier can safely transport 80,000 cubic meters of liquid hydrogen (LH2).

Safety and Efficiency in Design

Safety remains a top priority for both CB&I and Hanwha Ocean. According to Mark Butts, Senior Vice President for CB&I, their collaboration has resulted in a low boil-off rate of just 0.05% per day. This low rate is essential for operational efficiency and plays a crucial role in establishing future international supply chains for liquid hydrogen, a key element in the transition towards cleaner energy solutions.

Technological Innovations Behind the Design

Central to the success of this project is CB&I's vacuum-insulated double-wall sphere technology for LH2 transport. With over six decades of expertise in designing onshore LH2 storage tanks, CB&I's experience significantly enhances the viability of safe and effective hydrogen transportation.

Collaborative Efforts for Enhanced Performance

Youngchang Shon, CTO of Hanwha Ocean, emphasized the importance of their collaborative efforts with CB&I and DNV. The trio has been working together to ensure the design not only meets safety standards but is also environmentally friendly. Research has focused on various features, including the cargo handling system and an innovative electric propulsion system powered by hydrogen fuel cells.

Future Prospects for Liquid Hydrogen Transportation

As the industry faces new challenges, partnerships like those between CB&I and Hanwha Ocean are integral. Vidar Dolonen from DNV remarked on the remarkable cooperation that is now setting a standard in hydrogen and shipbuilding sectors. This partnership aims to enhance technical maturity and foster the development of new propulsion systems for liquid hydrogen carriers, which are vital for future energy transportation.
