Abstract
The recommended practice DNV-RP-C203 Fatigue Design of Offshore Steel Structures has been regularly revised since it was first published in 1998. The reasons for these revisions are new data and new learnings from design and in-service experience from installed structures. The standard is also being used for new types of details and structures, and this requires new information to the users of the document. New literature is being published and other standards related to fatigue design is being revised; therefore, a regular revision of this document is needed.
The standard is being used for fatigue design of different structures such as jackets, risers, pipelines, semisubmersibles, spars, floating production vessels, fixed and floating structures for support of wind turbine structures, different types of connectors, etc. This implies that the content needs to be applicable for many different details where the efficiency and reliability of the methods used are being challenged by the industry. During the last year the recommended practice has been through a critical review where the content has been updated where new information has become available.
