This International Standard specifies general principles for the design and assessment
of offshore structures subjected to known or foreseeable types of actions . These general principles are applicable worldwide to all types of offshore structures , including, bottom-founded structures as well as floating structures , and to all types of materials used including steel, concrete and aluminium.
This International Standard specifies design principles that are applicable to:
— the successive stages in the construction of the structure (i.e. fabrication, transportation and installation);
— use during its intended life; and
— its decommissioning .
The principles are also generally applicable to the assessment or modification of
existing structures . Aspects related to quality control are also addressed.
This International Standard is applicable to the design of complete structures , including substructures, topsides structures , vessel hulls, foundations and mooring systems.
