CB&I, a wholly owned unrestricted subsidiary of McDermott, and Korean world-class shipbuilder Hanwha Ocean have received Approval in Principle (AiP) for the design of a cargo containment system and an 80,000 m3 liquid hydrogen (LH2) carrier from DNV, a leading classification society for shipping. DNV formalized the AiP with executives from each company at the Gastech Exhibition & Conference held in Houston on September 17, according to McDermott International's release.
The AiP confirms CB&I's cargo containment systems meets applicable safety standards including class rules, the International Code for the Construction and Equipment of Ships Carrying Liquefied Gases in Bulk (IGC Code), as well as the Interim Recommendations for Carriage of Liquefied Hydrogen in Bulk, Resolution MSC.420(97), issued by the International Maritime Organization (IMO).
"Hanwha Ocean's expertise in gas carriers perfectly complements CB&I's expertise in large-scale storage and handling systems for liquid hydrogen," said 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."
CB&I is supporting Hanwha Ocean's carrier design with its cargo containment system consisting of vacuum-insulated double-wall spheres for LH2 transport, which has also been approved by DNV. CB&I has more than 60 years of experience in onshore LH2 storage tank design and construction worldwide.
