The classification society DNV has introduced Recommended Practice DNV-RP-0703, a new framework designed to define the competencies required for the safe use of hydrogen as a marine fuel. The guide establishes specific requirements for crews, inspectors, and technical personnel involved in the operation of hydrogen systems on board ships.
Hydrogen continues to gain traction as one of the alternatives considered by the maritime industry to reduce greenhouse gas emissions. Although several vessels are already operating with this technology and dozens of projects are under development, the commercial adoption of the fuel still faces significant challenges related to safety and operation.
A competency framework for an emerging technology
The new best practice aims to address the specific risks associated with hydrogen through a formal competency framework. Key aspects include leak management, the fuel’s low ignition energy, and the management of high-pressure or cryogenic storage systems.
According to DNV, the document can also be used as a reference for developing operating procedures, training programs, and emergency response plans. The initiative builds on the organization’s prior experience in developing standards for low-carbon fuels such as LNG, ammonia, and methanol.
Training as a fundamental element for safety
Cristina Saenz de Santa Maria, CEO of DNV’s maritime division, stressed that the development of human capabilities must advance at the same pace as technological solutions.
Hydrogen represents one of the potential pathways for decarbonizing the maritime sector. The development of effective safety regulations and guidelines is essential for hydrogen to move from large-scale demonstrations to commercial use.

He also explained that the training of sailors will be crucial to ensuring safe operations and building confidence in the use of this technology as its presence in the global fleet increases.
Support for shipowners and training centers
The guide has been designed to complement existing regulatory frameworks such as the International Convention on Standards of Training, Certification and Watchkeeping for Seafarers (STCW) and the International Safety Management (ISM) Code.
In this regard, shipowners can use it as a reference for crew familiarization and skills management on board. Similarly, maritime academies and training institutions will have a technical basis for designing educational programs focused on hydrogen operations.
In addition, independent bodies may use the document as a tool to verify training processes and evaluate professional skills related to this fuel.
Industrial collaboration to accelerate hydrogen adoption
Kirsten Birgitte Strømsnes, DNV’s Business Development Director, stressed that the incorporation of hydrogen requires a combination of specialized training, management systems adapted to the new risks, and ship designs that incorporate adequate safety barriers.
The recommended practice was developed using DNV’s competency standards methodology and involved companies and organizations in the maritime sector, including Samskip, eCap Marine, Naval Dynamics, Chart Industries, LH2 Shipping, Torghatten, Shell, Everllence and GreenH.
As operational experience with hydrogen-powered vessels grows, DNV plans to update this best practice to incorporate new lessons learned and industry best practices. The aim is to contribute to the safe implementation of hydrogen and facilitate its role within maritime decarbonization strategies.
