Materials and Floating Systems
Post Hurricane Response

7. ISO TC 67 Reactivation
SC 7 1st Meeting

8. Why change?
API has done a very good job in developing good offshore structures standards and continues to do so.
Why ISO

9. Factors causing change
Norwegian & UK and Classification Society regulations developed in part competing with API.
EU structural standards programme initiated with stated aim of including offshore structures.
Oil Companies moved from traditional geographic locations and suppliers to worldwide operations.
Worldwide cross-industry trend to give lower credence to industry standards than national or international standards.
Problem applied to the oil industry as a whole – not just offshore structures.

10. Industry Solution
Develop a single set of Oil Industry Standards through ISO.
Build on legacy of mainly API but also other industry standards.
ANSI given chair and secretariat of the ISO Committee overseeing the development of Oil Industry ISO Standards.
ANSI delegated secretariat to API.
Seven Subcommittees
SC 7 – Offshore Structures
BSI Secretariat
Large Work Plan, Multiple Work Groups and Panels

11. ISO Series Scope
Standardisation of all forms of fixed and floating offshore structure used in the production and storage of petroleum and natural gas and site specific assessment of mobile offshore units.

12. Impact of the Terrible Triplets
Serious impact on offshore infrastructure and significant loss of production
Keen interest from MMS on industry response
Reassessment of metocean data and severe hurricane characteristics
New insight into interaction with loop current
Publication of 6 interim bulletins on hurricane design
Metocean criteria for 4 sectors of GOM
How to use this criteria for design of new and assessment of existing structures
Accelerated schedule
Reappraisal of the long term approach to standards

13. Longer Term Approach to Standards
Need for single metocean document – to be based on ISO
Need for separate structural integrity management RP
Removal of metocean, fire and blast and reassessment criteria from RP 2A implies significant restructuring of the document
ISO standards reaching maturity and publication
Heightened industry interest in standards but manpower resources scarce
Maybe the time is now right to streamline the API offshore standards suite and align with the ISO standards per the original vision
