This document specifies general requirements and recommendations for the design and assessment of bottom-founded (fixed) and buoyant (floating) offshore structures.<\/p>\n
This document is applicable for all phases of the life of the structure, including:<\/p>\n
successive stages of construction (i.e. fabrication, transportation, and installation),<\/p>\n<\/li>\n
service in-place, both during design life and during any life extensions, and<\/p>\n<\/li>\n
decommissioning, and removal.<\/p>\n<\/li>\n<\/ul>\n
This document contains general requirements and recommendations for both the design of new build structures and for the structural integrity management and assessment of existing structures.<\/p>\n
This document does not apply to subsea and riser systems or pipeline systems.<\/p>\n
