What is this published document about?
This is the third in a five-part series on pipeline systems. This part provides a recommended framework for carrying out an assessment of the acute safety risks associated with a major accident hazard pipeline (MAHP) containing flammable substances as defined in the Pipelines Safety Regulations.
Who is this published document for?
- Pipeline operators
- Local planning authorities
- Developers
- Competent risk assessment practitioners involved in the risk assessment of developments in close proximity to existing major accident hazard pipelines
Why should you use this published document?
It provides guidance on the selection of pipeline failure frequencies and the modelling of failure consequences for the prediction of individual and societal risks.
The principles within this document are based on best practice for the quantified risk analysis of new pipelines and existing pipelines. It’s not intended to replace or duplicate existing risk analysis methodology, but to support the application of the methodology and provide recommendations for its use.
This document applies to buried pipelines on land that can be used to carry category D and category E substances that are hazardous by nature, being flammable and therefore liable to cause harm to persons.
This part of PD 8010 is intended to support the application of expert judgement. The final responsibility for the risk assessment lies with the assessor. It’s essential that the assessor is able to justify every key assumption made in the assessment and that these assumptions are documented as part of that assessment.
NOTE: PD 8010-3 should be read in conjunction with PD 8010-1.
What’s changed since the last update?
This first amendment to Part 3 of PD 8010 supersedes the 2009 document which has been withdrawn. Amendment 1 introduces the following principal changes:
- Clarification on application criteria for ALARP assessment and land use planning
- Updates to slabbing protective measures and depth of cover
- Updates to HSE methodology
- Updates to UKOPA failure frequency data
