Hydrogen fuelled ships: Comparative analysis of class rules and guidelines

Abstract

The IGF Code, originally designed around LNG storage and transport systems, falls short in adequately addressing the unique properties of hydrogen. As a result, efforts are currently underway to develop relevant regulations, including the release of CCC 9/WP.3. Leading classification societies like ABS, BV, DNV, KR, LR, NK, and RINA have established their own specific rules and guidelines for liquefied gases and LNG.
