DNV offshore rules incorporate knowledge and experience acquired over time and provide a consistent set of standards designed to ensure fail safe design and redundancy to prevent a failure from becoming a critical accident. The rules and supporting documents are subject to regular updating to reflect operational experience and advances in technology.
Documents for offshore class, the DNV Offshore Codes, consist of a 3-level hierarchy of documents:
Rules for Planning and Execution of Marine Operations are recognised worldwide by both the marine and offshore industry, and are commonly quoted as the basis reference for marine operations. The rules lay down technical and procedural requirements related to proper planning and execution of marine operations.
The world’s most comprehensive guideline for safe and sustainable geological storage of CO2
DNV’s core philosophy is that technology development and knowledge sharing increase innovation and safety. So when the industry is facing challenges, the best way of solving these is for industry players to join forces through Joint Industry Projects (JIPs). Together we in this way develop the world’s best practices and standards.
Class rules and supporting documents give criteria for design, construction and maintenance of offshore assets.

In response to the emerging offshore wind power market, DNV is launching the world’s first class notation for offshore wind turbine installation units.

In response to recent research and development work and the industry’s operational experiences with mooring systems, DNV has now released a complete set of Offshore Standards covering systems design, materials, product quality, certification requirements and the fabrication process.

The increase in exploration and production activities in deep waters has made the use of steel wire ropes as segments in mooring systems more common. This trend has motivated DNV and industry partners to issue a new steel wire rope mooring standard.
