scope:

The standard specifies general principles and guidelines for the structural design and the structural design verification of load bearing structures subjected to foreseeable actions.

The standard is applicable to all types of offshore structures used in the petroleum activities, including bottom founded structures as well as floating structures.

The standard is applicable to all types of materials used including steel, concrete, aluminium, etc.

The standard is applicable to the design of complete structures including substructures, topside structures, vessel hulls, foundations, mooring systems and subsea installations.

The standard specifies design principles that are also applicable to the successive stages in construction (namely fabrication, transportation and installation), to the use of the structure during its intended life, and to its abandonment. The standard also specifies principles applicable to the reassessment or modification of existing structures. Aspects related to verification and quality control are also addressed.
