DNV has awarded an Approval in Principle (AiP) to CB&I and Hanwha Ocean’s cargo containment system design for an 80,000m3 liquid hydrogen (LH2) carrier.
Under the AiP, CB&I’s cargo containment systems meet applicable safety standards including the International Code of the Construction and Equipment of Ships Carrying Liquefied Gases in Bulk (IGC Code) and certifications issued by the International Maritime Organisation (IMO).
The McDermott subsidiary, CB&I is providing the Korean shipbuilder with its cargo containment system that consists of vacuum-insulated double-wall spheres for LH2 transport, which was also approved by DNV.
“Hanwha Ocean’s expertise in gas carriers perfectly complements CB&I’s expertise in large-scale storage and handling systems for liquid hydrogen,” explained Mark Butts, Senior Vice President for CB&I.
“Together we have created a safe, efficient liquid hydrogen carrier design with low boil-off of 0.05% per day. This carrier makes plans for international liquid hydrogen supply chains possible today.”
The two companies have been working together for over a year on the LH2 carrier.
Youngchang Shon, CTO, Head of Product & Technology Strategy at Hanwha Ocean, said, “Our comprehensive research has included verifying the basic performance and structural safety, cargo handling system and the conceptual design of an eco-friendly electric propulsion system incorporating hydrogen fuel cells.”
Commenting on the AiP, Vidar Dolonen, Regional Manager of DNV Korea and Japan, said, “We are now witnessing an exemplary scene of cooperation where two global leaders in hydrogen and shipbuilding sectors work together closely to realise the shipping of liquid hydrogen.”
