Full title and description

St ISO 19901-9-2019 — Petroleum and natural gas industries — Specific requirements for offshore structures — Part 9: Structural integrity management. This International Standard defines principles, requirements and recommendations for planning, implementing and maintaining structural integrity management (SIM) programmes for offshore structures used in the petroleum and natural gas industries.

Abstract

This part of ISO 19901 specifies principles for structural integrity management (SIM) of offshore structures subjected to known or foreseeable types of actions. It covers requirements and guidance for integrity data, in-service inspection, assessment of existing structures, evaluation for reuse at other locations and considerations for future removal. The document is principally applicable to fixed steel offshore structures and topsides, but its requirements are also relevant to other bottom-founded and related offshore structures where appropriate.

• Number of pages: 143 (ISO published edition)

Scope

The standard applies primarily to fixed steel offshore structures (for example caissons, jackets, monotowers and towers) and associated topsides elements (main decks, modules, crane pedestals, helidecks, derricks, flare booms, lifeboat davits, etc.). It provides requirements and recommendations for SIM tasks including integrity data requirements, in‑service inspection planning and execution, assessment procedures for new and existing structures, evaluation for reuse at different locations and considerations for removal and decommissioning. Where relevant, the guidance may also be applied to compliant bottom‑founded structures, steel gravity structures, jack‑ups and other related marine structures.

Key topics and requirements

• Principles and framework for a documented Structural Integrity Management (SIM) programme.
• Integrity data requirements: record keeping, documentation and data quality needed for assessment and decision-making.
• In-service inspection (ISI) planning: risk‑based inspection concepts, inspection intervals, methods and acceptance criteria.
• Assessment of existing structures: structural evaluation, fitness‑for‑purpose assessments and remaining life estimation.
• Evaluation procedures for reuse or relocation of structures at new sites (including re-assessment of loads and environment).
• Guidance on planning and engineering for future removal and decommissioning assessments.
• Recommendations for integration of SIM with design, maintenance, operations and safety management systems.
• Roles and responsibilities, competence and verification requirements for organisations executing SIM activities.

Typical use and users

ISO 19901-9 is used by asset owners and operators, structural and offshore engineers, inspection and integrity teams, fabricators, engineering procurement and construction (EPC) contractors, consultants, and regulatory authorities. Typical applications include setting up SIM programmes for platforms and fixed structures, planning risk‑based inspection campaigns, conducting fitness‑for‑purpose assessments of aging structures, and evaluating options for reuse or decommissioning.

Related standards

Relevant standards that commonly interact with ISO 19901-9 include other parts of the ISO 19901 series (e.g., Parts 1, 2, 3, 4, 5, 6, 7, 8, 10), ISO 19902 (fixed steel offshore structures), ISO 19903 (concrete offshore structures), ISO 19904 (floating structures), ISO 19905 (jack-ups/site assessment) and ISO 19906 (arctic offshore structures). Industry codes and guidance such as API RP documents and leading classification society standards are also commonly referenced alongside ISO 19901-9 in integrity and inspection practice.

FAQ

Q: What is this standard?

A: ISO 19901-9:2019 provides principles, requirements and recommendations for structural integrity management (SIM) of offshore structures used in the petroleum and natural gas industries.

Q: What does it cover?

A: It covers integrity data requirements, in‑service inspection planning and execution, assessment of existing and new structures, evaluation for reuse at new locations, and considerations for future removal and decommissioning—primarily for fixed steel offshore structures and related topsides components.

Q: Who typically uses it?

A: Asset owners, operators, structural engineers, inspection and integrity specialists, EPC contractors, consultants and regulators use ISO 19901-9 to establish and run SIM programmes and to perform assessments and inspection planning for offshore structures.

Q: Is it current or superseded?

A: The published edition is ISO 19901-9:2019 (Edition 1, July 2019). The 2019 edition is the current published version; a revision process (new committee work) has been initiated at ISO for a subsequent edition, so users should check for any newer edition or committee drafts when applying the standard.

Q: Is it part of a series?

A: Yes. ISO 19901-9 is part of the ISO 19901 family of documents dealing with specific requirements for offshore structures; it is commonly used alongside related ISO 19901 parts and other ISO/TC 67 standards for offshore design, assessment and investigations.

Q: What are the key keywords?

A: Structural integrity management, SIM, in‑service inspection, fixed offshore structures, topsides, fitness for purpose, risk‑based inspection, decommissioning, reuse assessment.
