This International Standard specifies general principles for the design and assessment of structures subjected to known of foreseeable types of actions. These general principles are applicable worldwide to all types of offshore structures including bottom-founded sturctures as well as floating sturctures 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 contruction (namely fabrication, transportation and installation), to the use of the structure during its intended life and to its decomissioning. Generally, the principles are also applicable to the assessment or modification of existing structures. Aspects related to quality control are also addressed.
