Petroleum and natural gas industries — Specific requirements for offshore structures — Part 9: Structural integrity management
This document specifies principles for the structural integrity management (SIM) of offshore structures subjected to known or foreseeable types of actions. This document specifies requirements and provides recommendations applicable to the following types of fixed steel offshore structures for the petroleum and natural gas industries: — caissons, free-standing and braced; — jackets; — monotowers; — towers. This document is applicable to topsides, including but not limited to the main decks, deck legs, topsides modules, crane pedestals, helideck, drilling derrick, skid beams, flare booms, exhaust towers, radio tower, conductor support frames, and lifeboat davits. In addition, it is applicable to compliant bottom founded structures, steel gravity structures, jack-ups, other bottom founded structures and other structures related to offshore structures (e.g. underwater oil storage tanks, bridges and connecting structures), to the extent to which its requirements are relevant. This document contains requirements for planning and engineering of the following tasks: a) integrity management data requirements; b) in-service inspection and integrity management of both new and existing structures; c) assessment of existing structures; d) evaluation of structures for reuse at different locations; e) evaluation of structures for their future removal.
ISO 19901-9:2019 - Structural integrity management (SIM) provides principles, requirements and recommendations for managing the structural integrity of fixed steel offshore structures in the petroleum and natural gas industries. The standard applies to caissons (free‑standing and braced), jackets, monotowers, towers and associated topsides items (main decks, deck legs, crane pedestals, helidecks, derricks, flare booms, lifeboat davits, etc.). It is also applicable, as relevant, to compliant bottom‑founded structures, steel gravity structures, jack‑ups and related structures (underwater storage tanks, bridges and connectors).
ISO 19901-9 structures its guidance around a lifecycle SIM approach and includes requirements for planning, engineering and execution of integrity tasks. Major technical topics include:
ISO 19901-9 is used to develop and implement structured integrity management programs for offshore assets to ensure safety, regulatory compliance and cost‑effective lifecycle management. Typical applications:
Упомянутые в описании и другие стандарты ISO
ISO 19901-9 should be used alongside other parts of the ISO 19901 series and applicable national/international offshore design, inspection and fitness‑for‑service codes to form a complete integrity management framework.
