DNV GL publishes new classification rule set

DNV GL publishes new classification rule set
Just two years and three weeks after what was described as the biggest merger in shipping history, classification society DNV GL has published a new rule set which it says combines the experience and expertise of its two forebears, while at the same time modernizing and future-proofing the rules.

The new DNV GL rules will enter into force on 1 January 2016.

“This is an historic moment,” said Remi Eriksen, DNV GL Group president and ceo, alluding to a very “thorough process” that had involved a high degree of “invaluable” engagement by customers and other industry stakeholders.

Over 7,000 pages were reviewed, both internally and externally, in developing the new rules, and in all more than 2,000 detailed comments by yards, manufacturers, owners, academics, flag states and other maritime stakeholders were submitted, resulting in more than 700 rule modifications.

Knut Ørbeck-Nilssen, ceo of DNV GL – Maritime, said the group had taken advantage of a “unique opportunity to have a fresh look at our rules”, thereby creating what he described as “a new industry benchmark”.

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

DNV GL points out that more modern tools and software have also been incorporated, making the rules more attuned to future developments, and that latest technologies such as battery installations and hybrid propulsion concepts, gas-fuelled readiness and LNG bunkering vessels are catered for through additional class notations.
