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 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.

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 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
