Bureau Veritas Marine & Offshore is actively engaged in the NavHyS project, a European research initiative focused on advancing the utilization of liquid hydrogen in maritime settings to reduce carbon emissions. Funded by the Clean Hydrogen Partnership, the project's consortium, which includes 14 partners from across Europe, aims to decarbonize the shipping industry. BV's collaboration with ArianeGroup is pivotal in developing the project proposal and structure. BV's role encompasses providing expertise in safety, rule development, and classification, particularly in supporting innovation for hydrogen-fueled vessels. The project specifically concentrates on the technical challenges of employing below-deck Type C LH₂ tanks for service operation vessels (SOVs), with BV tasked to deliver three Approvals in Principle for the liquid hydrogen storage system, fuel system, and their integration into SOVs. BV's commitment to cutting-edge technologies is evident through its involvement in this consortium, emphasizing the importance of maritime decarbonization. Additionally, BV will lead research on safety and rule development for liquid hydrogen, explore shore-based hydrogen supply solutions, and investigate the lifecycle of hydrogen-fueled vessels. The NavHyS project, commenced in January 2025 with EU funding of €5 million, aims to achieve Technology Readiness Levels 8-9 by 2030 to facilitate scalable deployment of hydrogen-powered vessels by 2035-2040. By combining maritime design expertise with knowledge from the space sector in cryogenic storage, the project strives to revolutionize the design of SOVs supporting offshore wind farms. The envisioned design includes storage tanks capable of holding 12-18 tonnes of liquid hydrogen, providing up to 10 days of autonomous operation.
