Research into the enduring management of safety risks on pipelines and above ground installations. The project includes the implementation of the results via tools and methodologies that are aligned specifically to National Grid’s needs but are also relevant to the UK gas industry, utilising the results of the international collaborations as appropriate. Through collaboration with other gas transmission companies, National Grid is able to demonstrate to the safety regulator, its customers and the general public, through its safety cases, that its knowledge of gas transmission hazards and risks is at the forefront of current thinking and therefore that its safety cases are credible and realistic. Such collaboration also allows National Grid to participate in, and benefit from: the ongoing development of international best practice in risk management and shared learning from incidents.

The continuous management and improvement of safety risks on gas transmission pipelines and above ground installations requires development of wide ranging models and procedures. As the type of event which affects such assets is of low frequency, but extremely high consequences it requires accurate models to make safety decisions and keep risks as low as reasonably practicable. Historically, the efficient development of these models and procedures has been coordinated through joint ventures. The maintenance and participation in these joint venture initiatives offers considerable benefits in terms of the latest thinking and best practice. Proposed activities for 2016/17 are as follows: Hazard and Risk Assessment Methods for Gas Transmission Pipelines Data for Failure Frequency Estimation for Use in Risk Analysis Hazard and Risk Assessment Methods for Above-Ground Installations Parallel Pipelines Effectiveness of Safety Measures The activities shown below are broken down by contribution in 3 parts: National Grid Gas Transmission (NGGT) National Grid Gas Distribution (NGGD) Contribution from Partners (CFP) Hazard and Risk Assessment Methods for Gas Transmission Pipelines:- NGGT: £22. 0k NGGD: £22. 0k CFP: £70. 0k Data for Failure Frequency Estimation for Use in Risk Analysis:- NGGT: £7. 32k NGGD: £7. 32k CFP: £24. 6kHazard and Risk Assessment Methods for Above-Ground Installations:- NGGT: £13. 75k NGGD: £13. 75k CFP: £35. 0kParallel Pipelines:- NGGT: £1. 32k NGGD: £1. 32k CFP: £8. 4kEffectiveness of Safety Measures:- NGGT: £1. 16k NGGD: £1. 16k CFP: £14. 4kTOTAL:NGGT - £45. 55kNGGD - £45. 55kCFP - £160. 6kNote : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above
