DNV GL Publishes New Classification Rule Set

DNV GL's new rules for classification of ships become publicly available online today following a development and review process involving 250 internal experts and more than 800 customers and maritime stakeholders.

The result of the combined experience and expertise of two classification societies, the new rules are modern, easy to work with, industry-driven, efficient and ready for the future, DNV GL said.

“This is an historic moment,” said Remi Eriksen, DNV GL Group President and CEO. “After such a thorough process it is very exciting to launch the new DNV GL classification rules. The engagement of our customers and industry stakeholders has been overwhelming. From our initial discussions, through the review and external hearing process we have received invaluable input and we are deeply grateful for the consideration and enthusiasm of all involved. I look forward to following the many joint development projects using the new classification rules already underway.”

“I’m proud we took advantage of the unique opportunity to have a fresh look at our rules and have created a new industry benchmark,” said Knut Ørbeck-Nilssen, CEO DNV GL – Maritime. “The dedication of our customers has been outstanding. Together with them we have truly taken up the challenge of taking classification into the future. I believe this new rule set gives us an even better basis to deliver the safety, efficiency and quality our customers expect.” 

Through the process of developing the new DNV GL rules over 7,000 pages were reviewed, both internally and externally. In all, more than 2,000 detailed comments by yards, manufacturers, owners, academics, flag states and other maritime stakeholders were submitted. This consultation process resulted in more than 700 rule modifications – adjustments triggered directly by the industry’s expertise.

According to DNV GL, one of the most significant advances in the new rules is the introduction of Equivalent Design Waves (EDW) to calculate environmental loads. EDW enables a more accurate representation of these loads and consequently a more precise stress description of a vessel’s structure.

The reworking of the rules has allowed DNV GL to incorporate and integrate more modern tools and software, making them responsive to future developments, the classification society said. The rules also support the application of the latest technologies including battery installations and hybrid propulsion concepts, gas-fuelled readiness and LNG bunkering vessels through additional class notations.
