- A unique and successful 5th ISO Seminar on International Standardization in the Reliability Technology and Cost Area, 1 December 2022, Paris
A new seminar was held Thursday 1 Dec 2022 in Paris and efficiently hosted by TotalEnergies. It was great to meet again face to face since last seminar held in Houston in May 2018. A high number of company and management/technologists from 8 countries in Eastern and Western Hemisphere attended - contributed to and acknowledged to learn and share a lot in an effective afternoon. The attendants included operators, contractors, consultancies, research institutes and standards development organizations.
This ISO seminar organized by ISO/TC 67/WG4 “Reliability engineering and technology” provided an excellent overview of standards developed and its industry applications also essential for meeting the international collaboration arena including now also Lower Carbon Energy. This was accomplished by these four sessions and an interactive Q&A session:
• Management of standards development and use in an energy transition context
• Cost management in the energy industries
• Digitalized applications for equipment performance using quality data based on ISO 14224
• ISO/TC67/WG4 standards as enablers to meet safety requirements

- A new ISO/TS 3250 Calculation and reporting of production efficiency (PE) in the operating phase has been issued based on recent standards development work by ISO/TC67/WG4. It provides requirements and guidance for reporting of production performance data and production loss data in the operating phase by use of production loss categorization. This will enable precise and consistent feedback of production performance for use in production and operational planning to achieve optimal PE for the operators and associated industry stakeholders.
- A new 1st edition of ISO 15663 ‘’Life cycle costing’’, as developed by the ISO/TC67/WG4 has been published 25 February 2021. It contains requirements and guidance on how to implement and apply the life cycle costing methodology, to provide decision support for selection between alternative competing options. The use of ISO 15663 enables strengthening of the industry cost management for business value creation. The standard also contains unique key economic evaluation measures such as LCC (life cycle cost) and NPV (net present value). The oil and gas operators, contractors and vendors are the main users of ISO 15663.

Work programme
Production assurance and reliability related terminology
Terminology is of key importance and the use of terms and definitions in the ISO standards will be beneficial for efficient verbal and written communiucation amongst relevant stakeholders and avoids ambiguity in the use of terms. The new document N2123 has been made by the ISO/TC 67/WG 4 expert members for indicated languages with the objective to translate selected terms appearing in some key ISO/TC 67/WG 4 documents. The ISO 14224:2016, ISO 20815:2018, ISO/TS 3250:2021 and ISO/TR 12489:2013 have been developed by ISO/TC 67/WG 4 – for standardization within the oil and gas industries including lower carbon energy.
See further information in N2123_Update on ISOTC67WG 4 document_Definitions and Translations_2023 (8 March 2023)
Cost related terminology
Terminology is also of key importance for cost terms. A new document N1952 has thus also been made by the ISO/TC 67/WG 4 expert members for indicated languages with the objective to translate selected cost terms appearing in the following ISO/TC 67/WG 4 documents ISO 19008:2016 and ISO 15663:2021. The latter has recently been developed by ISO/TC 67/WG 4 – for standardization within the petroleum, petrochemical and natural gas industries.
See further information in N1952 - ISO/TC 67/WG 4 document: Definitions and translations of cost terms (9 July 2021)
ISO 19008 Standard cost coding structure for oil & gas industries including lower carbon energy
ISO 19008, Standard Cost Coding System, is designed to provide a uniform coding basis for cost and quantity data in a life cycle perspective – from estimate preparation to cost management and collecting historical data to facilitate benchmarking, analysis and consistent comparison across projects and assets. At present, energy systems worldwide are shifting focus towards decarbonization and renewable energy systems, being part of the growth strategies for the industry going forward. The ISO/TC67/WG4 recognizes the need for the ISO 19008 to adapt to this changing business environment. In addition to classifications for traditional oil and gas facilities, the standard currently contains classifications fit for CCS (Carbon Capture and Storage) and offshore wind energy projects. Lessons learned in oil and gas will give business opportunities for use of the same approach in renewable projects.
ISO/TR 12489:2013 - Reliability modelling and calculation of safety systems
ISO/TR 12489 is an important supplement of IEC 61508-part 6 (functional safety), but also for all systems with safety functions that not necessarily have SIL-requirement. The ISO Technical report has been developed by a project group in ISO/TC67/WG4, and it provides guidelines with focus on reliability modelling & calculation. Courses have been developed and will be made.
See further information in ISO/TR 12489 - Information sheet, 2024-11-19
The ISO/TC67/WG4/PG3 leadership has in collaboration with ESREL organized a special session related to ISO/TR 12489 and other functional safety related standards at the 31st European Safety and Reliability Conference, 19-23 September 2021, Angers, France. See more information of the special session on Reliability, Availability and Maintainability of Safety systems, at ESREL session web page.
ISO 15663 “Life Cycle Costing”
The previous 1st editions issued 2000/2001 (Part 1, 2 and 3) have been merged into a single document. The new 1st edition issued in Feb 2021 contains requirements and guidance on how to implement and apply the life cycle costing methodology, to provide decision support for selection between alternative competing options. It enables strengthening of the industry cost management for business value creation. The standard also contains unique key economic evaluation measures such as LCC (life cycle cost) and NPV (net present value). The oil and gas operators/energy companies, contractors and vendors are the main users of ISO 15663. The life cycle costing methodology, framework and guidance provided in ISO 15663 is already suitable for the extended ISO/TC67 scope arena for lower carbon and renewable energy industries, e.g. CCUS (Carbon Capture Utilization Storage), offshore wind, hydrogen projects, etc.
Note that ISO 15663 courses have been held 9 June 2021 and 19-20 March 2024. To show interest for similar course in the future, please express interest on the course interest link further below. See also below links to OTC 2021, ONS 2022 and OTC 2023 and OTC 2024 conference papers regarding ISO 15663.
ISO/TS 3250 “Calculation and reporting of production efficiency in the operating phase”
A new ISO/TS 3250 Calculation and reporting of production efficiency (PE) in the operating phase has been issued based on recent standards development work by ISO/TC67/WG4. It provides requirements and guidance for reporting of production performance data and production loss data in the operating phase by use of production loss categorization. This will enable precise and consistent feedback of production performance for use in production and operational planning to achieve optimal PE for the operators and associated industry stakeholders.
Marketing and dissemination
