The desired result will be a fully validate pipeline risk ranking model. Delivery and implementation of the model with guidance documents

National Grid operates high pressure pipelines across a wide variety of locations from rural and suburban. Whilst the pipelines are all exposed to similar threats, including third party damage, ground movement, fatigue and corrosion, the extent of the threat varies dependent upon the pipeline location and construction standards in place at the time of build. The current approach is generally to use standard procedures for all pipelines which do not take into account specific risks for individual pipeline sections (with the exception of inline inspection). The project looks to undertake a study to develop a model that takes into account the threats posed by different damage mechanisms on individual pipeline sections and ranks the relative risks of failure so that high risk sections can be identified and inspection, maintenance and mitigation actions applied appropriately. The Model Development consists of: Development of interactive aspects of the model Independent expert review of risk scoring logic Development of a strategy to compare risk ranking model against quantified risk assessment Verification of risk scoring logic using case studies and refine based on (b)Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above
