What is ISO 19900 about?
ISO 19900 specifies general requirements and recommendations for the design and assessment of bottom-founded (fixed) and buoyant (floating) offshore structures.
ISO 19900 is applicable for all phases of the life of the structure, including:
- Successive stages of construction (i.e. fabrication, transportation, and installation),
- Service in-place, both during design life and during any life extensions, and
- Decommissioning, and removal.
ISO 19900 contains general requirements and recommendations for both the design of new-build structures and for the structural integrity management and assessment of existing structures.
Note: BS EN ISO 19900 does not apply to subsea and riser systems or pipeline systems.
Who is ISO 19900 for?
ISO 19900 on general requirements for offshore structures is useful for:
- Offshore construction and installation companies
- Offshore oil and gas companies
- Offshore environment regulators
- Petroleum and natural gas industries
- Safety assurance services for offshore production
- Disaster management services
Why should you use ISO 19900?
Structural integrity is an overall concept comprising: models for describing actions, structural analyses, design rules, safety elements, workmanship, quality management, and national requirements, all of which are mutually dependent. The modification of any of these elements in isolation can cause an imbalance or inconsistency, with a possible impact on the reliability inherent in the offshore structure. The implications involved in modifying one element, therefore, need to be considered in relation to all the elements and the overall reliability of the offshore structure.
ISO 19900 enables you to achieve adequate structural integrity and performance based on reliability levels appropriate for manned and unmanned offshore structures, whatever the nature or combination of the materials used.
What’s changed since the last update?
BS EN ISO 19900:2019 supersedes EN ISO 19900:2013.
BS EN ISO 19900:2019 includes some technical changes with respect to EN ISO 19900:2013. These include:
- Terms and definitions have been updated
- Design/assessment situations are described, and the process for limit state design/assessment verification has been clarified
- Contents have been reorganized and many clarifications to provisions have been made
- Annex A has been reorganized to mirror the numbering of the normative clauses and it has been updated with substantial guidance moved from normative clauses.
