This Handbook is an important contribution on the path to its safe and efficient introduction, as well as the use of hydrogen as marine fuel. The information in it will provide guidance on how to deal with the current safety and regulatory barriers.
The Handbook is a product of the Maritime Hydrogen Safety (MarHySafe) Joint Development Project (JDP) and developed by DNV in collaboration with all the partners and observers in Phase 1, with input from the Norwegian Kolbjоrn Berge Leader of the Steering Committee MarHySafe JDP Norwegian Maritime Authority Maritime Authority. The Handbook provides a basis for a roadmap to hydrogen safety for the maritime industry, based on the current risk-based Alternative Design approval framework.
MarHySafe is a collaborative project involving the private business community as well as public authorities, and aims to support an increased uptake of hydrogen as an environmentally friendly solution for ships.
