Presentation Transcript

  1. Offshore StructuresUpdate • Bob Wolfram • Subcommittee 2 Strategy Group

  2. OTC 19606:API Offshore Structures Standards: Changing Times Dave Wisch Andrea Mangiavacchi OTC 19605:ISO 19900 Series: Offshore Structures Standards Richard Snell Dave Wisch

  3. Impetus for Change • Development of ISO 19900 series of offshore structures standards • Hurricanes – • Ivan • Katrina • Rita

  4. Scope

  5. RP 2A Materials and Floating Systems Post Hurricane Response

  6. ISO TC 67 Reactivation SC 7 1st Meeting

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

  8. 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.

  9. 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

  10. ISO 19900 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.

  11. 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

  12. Longer Term Approach to Standards • Need for single metocean document – to be based on ISO 19901-1 • 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

  13. API/ISO - “Wrapper”

  14. API vs. ISO Alignment - 2007

  15. API vs. ISO Alignment – 2010 Vision

  16. 2008 API Work Activities
