DNV enhances class rules for offshore units

Class rules prescribe how the regulations are to be met and help the owner and yard in designing and constructing vessels. But achieving an optimal result requires a delicate balance between detailed prescriptive vs. functional and more general requirements. The first ensure predictable and transparent results, while the latter allow the application of alternative solutions, according to DNV.
“As before, the rules are aligned with the IMO MODU Code, International Association of Classification Societies (IACS) Unified Requirements and other relevant international standards and codes. However, in addition, they include a comprehensive description of interpretations. This makes the rules’ requirements easily understandable for application throughout the design, construction and operation of the asset,” said Erik Henriksen, director for mobile offshore units at DNV.
The enhanced and restructured format is now open for comments during an external six-week consultation period. Subsequently, DNV will update the standards based on the input received, followed by formal publication.
