SECO MARINE: Underdeck Hydrogen Storage System with Bureau Veritas Approval

Bureau Veritas Marine & Offshore has granted an Approval in Principle (AiP) to SECO MARINE for its underdeck hydrogen storage system, marking a significant step toward adopting alternative fuel technologies in the maritime industry while adhering to current safety standards. The system, compliant with Bureau Veritas’ NR678 rule for hydrogen-fueled ships, utilizes Type 4 tanks to store compressed gaseous hydrogen, powering fuel cells and offering a new approach to low-emission ship design. Bureau Veritas Marine & Offshore executive vice president Matthieu de Tugny highlighted that supporting innovative, compact, and robust hydrogen systems contributes to a sustainable shipping future, with collaboration with pioneers like SECO MARINE accelerating the shift toward global decarbonization goals.

The system’s development stemmed from a research program focused on risk reduction and the creation of patented components with enhanced safety features for maritime environments. SECO MARINE Marine Hydrogen Projects leader Benoit Perrot congratulated the teams and partners, giving special thanks to the “France 2030” program and the Pays de la Loire Region for their crucial support.
