UKOPA Fault and Risk Assessment Work Group Terms of Reference


  • Act of behalf of UKOPA Members as the expert body on pipeline risk assessment and pipeline fault data issues.
  • Support, on behalf of member companies, the development and acceptance of appropriate pipeline risk assessment methodologies
  • Collect pipeline fault data, develop, maintain and periodically report on pipeline faults and damage to the notified major accident hazard pipeline population in the UK.
  • Provide the specialist / expert point of contact for UKOPA internal and external communications on pipeline risk assessment and pipeline fault data related issues.
  • Provide a formal UKOPA interface with HSE for discussions related to the collection of pipeline fault data; the development of pipeline risk assessment methodologies; the definition of risk criteria, land use planning, design codes related to risk assessment and pipeline routing and any changes to legislation related to these areas.


  • Establish, maintain and develop liaison with HSE, develop technical papers and case studies for HSE consideration and comment, in order to ensure a rational and logical approach by the Industry and Regulatory Authorities towards pipeline risk assessment and the assessment of individual and societal risk.
  • Develop, review and update the Industry view on application of risk assessment and risk criteria for land use planning, design codes (IGEM/TD/1, IGEM/TD/2, BS8010, ISO) and pipeline routing.
  • Review and update methodologies for the risk assessment of pipelines transporting hazardous fluids.
  • Review proposals made by the HSE (and EA) for future changes to pipeline safety legislation with regard to type of hazardous materials and risk assessment processes.
  • Specific areas of interest to include failure frequency data, release rates and failure mechanisms, dispersion, immediate and ultimate consequences and mitigation aspects.
  • To develop and promote the use of pipeline probabilistic methods of modelling utilising UK fault data when assessing risks and design for UK pipelines.
  • Develop an Industry view of acceptable risk criteria for the assessment of hazardous pipelines.
  • Develop a database of the population of damage, faults and failures for notified major accident hazard pipelines including preparation of a standard input format and reporting.
  • Collect pipeline damage and fault data and issue/publish a formal report every 2 years on pipeline failure data. A summary will be issued internally to the FARWG group annually
  • Publish pipeline failure data in the public domain and promote the use of UK pipeline fault and failure data in design and risk assessments for UK pipelines.
  • To review the extension of the pipeline fault database to encompass other UK pipelines, including both additional MAHP lines and other products.
  • Share across member companies pipeline risk assessment approaches and the collection and use of fault and recommend a consistent approach to UKOPA members.
  • Proactively develop and progress UKOPA input to pipeline risk publications, conferences and seminars.


The Working Group reports to the UKOPA Board and provides updates at the main UKOPA meetings to the wider UKOPA membership.

The membership is drawn from interested UKOPA members, together with other relevant advisers / parties agreed by UKOPA. Current UKOPA companies represented on the group are:-

BPA, Cadent, CATS, CLHPS, DNV-GL, Essar, Gas Network Ireland, INEOS, National Grid, NGN, Sabic, SGN, Swissgas, Valero, WWU

An up to date list of the names of the representatives of the member companies of the group will be maintained by the meeting Secretary along with a list of the relevant company contact names for supplying fault and failure data.


Meetings are arranged as required to progress current workload.


A record of the key deliverables of the Group is recorded and maintained by the group. These deliverables are consistent with the group’s agreed objectives in the UKOPA strategy document. Progress against these deliverables is reported to UKOPA members at the main UKOPA meeting. Any expenditure incurred in producing these deliverables is approved by the UKOPA Board prior to any work being commissioned.

If your organisation is a member of UKOPA and you would like to have a representative on this working group, please contact the secretary –

If your organisation is not a member of UKOPA but you would be interested in finding out more, again please contact the secretary –
