GB/T 23511-2021Petroleum and natural gas industries - General requirements for offshore structures (English PDF)

1 Scope

This document specifies general requirements and recommendations for the design and assessment of subsea (fixed) and floating (floating) offshore structures:

This document applies to all phases of the structural life cycle, including:

--- successive stages of construction (including fabrication, transport and installation);

--- In-service service stage, including design life and life extension period;

--- Disposal stage:

This document contains general requirements and recommendations for the design of new structures, structural integrity management and assessment of existing structures:

This document does not apply to subsea and riser systems or piping systems:
