ABS grants AiP for HD KSOE's Hydrogen Vacuum Insulation System

HD Korea Shipbuilding & Offshore Engineering (HD KSOE) has received ABS approval in principle (AIP) for a tank design that enables large-scale hydrogen transport and storage.The vacuum insulation system from HD KSOE is designed to reduce the time required to create a vacuum in large tanks, essential for transportation. The new technology allows maintaining a vacuum state at –253℃, which KSOE says enables safer and loss-free transport of large quantities of liquid hydrogen.ABS completed design reviews based on class and statutory requirements.
Large Vacuum-Insulated Liquid Hydrogen Tank Gains AiP

Lloyd's Register (LR) has awarded Approval in Principle (AiP) to HD Korea Shipbuilding & Offshore Engineering (HD KSOE) for its pioneering vacuum-insulated large-scale liquid hydrogen (LH₂) tank system. The successful testing of a large-scale vacuum chamber for this AiP marked the world’s first technical validation of large-scale LH₂ tank insulation design.The vacuum insulation system addresses some of the most pressing challenges of using hydrogen in the maritime industry: the scalability of liquefied hydrogen storage and transportation of the fuel, says LR.
DNV Gives Its Blessing for New LH2 Carrier Developed by Industry Partners

Certification body DNV has issued an approval in principle (AiP) for an 80,000m3 capacity liquefied hydrogen carrier, jointly developed by Mitsui O.S.K Lines (MOL), Woodside, HD Korea Shipbuilding and Offshore Engineering (HD KSOE), and Hyundai Glovis.MOL has been working with the partners to develop a liquefied hydrogen carrier since January 31, 2024.DNV’s AiP follows the completion of the hazard identification study (HAZID), a safety evaluation method for plants and systems…
Alfa Laval Gets DNV’s AiP for Hydrogen Carriers Gas Combustion Unit

Alfa Laval has secured Approval in Principle (AiP) from the classification society DNV for its Gas Combustion Unit (GCU) technology for hydrogen boil-off gas to be used on liquid hydrogen carriers.The AiP affirms the technical feasibility and safety mechanism of the GCU design and concept.The boil-off gas technology is essential for liquid hydrogen carriers, as venting cargo is restricted and a GCU is needed to control tank pressure and temperature to safely combust hydrogen boil…
Liquified Hydrogen Bunkering will be More Complex than LNG

The Maritime Technologies Forum (MTF), a forum of flag states and classification societies, has released a new report offering guidelines and key safety considerations for developing liquefied hydrogen bunkering systems and procedures.The report underlines the potential use of hydrogen as a zero-emission fuel to meet the IMO Strategy on Reduction of GHG Emissions from Ships by 2050. It acknowledges the challenges associated with bunkering hydrogen as marine fuel and as a maritime cargo…
MOL Embarks on Liquid Hydrogen Transport Study

Mitsui O.S.K Lines (MOL) has signed non-binding memorandum of understanding (MoU) with Woodside Energy, HD Korea Shipbuilding and Offshore Engineering (HD KSOE), and Hyundai Glovis to jointly study the development of shipping solutions to enable bulk marine transportation of liquid hydrogen.Woodside Energy, HD KSOE and Hyundai Glovis have been studying liquid hydrogen transportation since 2022.In this project, the participating companies will study the technology, safety, construction…
