DNV, a leading classification society, has released significant updates to its rules for classifying existing ships and offshore structures. These changes focus on supporting the adoption of clean technologies and improving clarity for ship operators.

“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.”

A key innovation is the new “in-operation class framework” with dedicated notations for existing fleets. This allows owners to demonstrate their use of advanced procedures and reporting for improved safety and efficiency. It also clearly defines responsibilities between shipyards (for new builds) and owners (during operation).

Unlocking Innovation: Hydrogen Power and Onboard Carbon Capture

The updated rules further solidify DNV’s leadership in maritime decarbonization. Two new notations pave the way for cleaner shipping:

  • Gas Fueled Hydrogen: This notation outlines requirements for hydrogen fuel systems, bunkering procedures, and fuel consumers, aiding owners in developing hydrogen-powered vessels.
  • OCCS (Onboard Carbon Capture and Storage): This notation provides a framework for these new systems, including exhaust treatment, capture, storage, and transfer of CO2 to shore, allowing existing ships to reduce emissions.

Additional Highlights:

  • Boil-off Gas (BOG) Notation: Establishes requirements for pressure and temperature control systems in liquefied gas tanks.
  • Live Fish Transport Notation: Creates a new classification for this growing industry.
  • Stability Pontoon Notation: Provides guidance for these crucial components used in heavy lifting operations.

  • Hatchcoverless Notation (NC Qualifier): Allows vessels not carrying combustible materials to reduce fire safety equipment investments.
  • Floating Spaceport Notation: Sets requirements for launching and recovering spacecraft.
  • Additional Fire Safety (EV Qualifier): Specifically targets vessels transporting electric vehicles.
  • Revised Diving System Rules: Aligns with the latest IMO 2023 diving code.

These updates demonstrate DNV’s commitment to fostering a cleaner and more innovative future for the maritime industry.
