Classification society DNV has updated its rules for the classification of ships and offshore structures, introducing two new class notations for hydrogen-fueled newbuilds and carbon capture and storage onboard ships.
According to DNV, the new in-operation class notations seek to bring clarity to the responsibilities of class customers for notations that have a mix of design and operational requirements.
With the in-operation notations, DNV has developed the first classification framework with dedicated Fleet in service notations that enable owners and operators to showcase how they are differentiating themselves in the market by deploying advanced procedures and reporting processes for greater safety and efficiency. The new notation clearly shows the split of responsibilities between the yards for the new building phase and the owners and operators in the operational phase of the vessel, DNV explained.
Two new class notations include Gas fuelled hydrogen and OCCS for carbon capture and storage onboard vessels.
The Gas fuelled Hydrogen notation sets out the requirements for the ship’s fuel system, fuel bunkering connection, and consumers, providing owners a practical path to develop hydrogen-fueled newbuildings.
The OCCS notation offers a framework and requirements for onboard carbon capture and storage (OCCS) systems, including exhaust pre-treatment, absorption, after-treatment systems, liquefaction, CO2 storage, and transfer ashore.
Some of the additional highlights of the rules include:
Published on July 1, the new rules will enter into force on January 1, 2025.
“One of the most striking aspects of the maritime industry today, is the huge diversity of challenges and opportunities where our customers are looking for classification support,” said Geir Dugstad , DNV Maritime’s Global Technical Director.
“It’s not just new fuels, but ways for owners and managers to demonstrate their own efficiencies, new vessel types to unlock new markets, through to advanced technologies like on-board carbon capture.”
