|Publication Date:||1 July 2019|
Scope and application
The standard is applicable to all types of offshore structures of steel.
For other materials, the general design principles given in this standard may be used together with relevant standards, codes or specifications.
The standard is applicable to the design of a unit's complete structures including hull structure, substructures, topside structures, and foundations.
This standard gives requirements for the following:
- design principles
- structural categorization
- material selection and inspection principles
- design loads
- load effect analyses
- design of steel structures and connections
- corrosion protection
- foundation design.
For application of this standard as technical basis for classification, see Ch.3.
Flag and shelf state requirements are not covered by this standard.
Governmental regulations may include requirements in excess of the provisions of this standard depending on the type, location and intended service of the offshore unit or installation. The 100 year return period is used to ensure harmonisation with typical Shelf State requirements and the code for the construction and equipment of mobile offshore drilling units (MODU code).
