RR1034 – Review of the event tree structure and ignition probabilities used...
HSE uses the MISHAP (Model for the estimation of Individual and Societal risk from HAzards of Pipelines) model to calculate risks associated with major hazard pipelines in GB. The review took place in...
View ArticleRR1035 – Update of pipeline failure rates for land use planning assessments
HSE uses a model, MCPIPIN (Monte Carlo PIPeline INtegrity), to determine failure frequencies for major hazard pipelines. It uses two models; one based on operational experience data and a predictive...
View ArticleRR1036 – Rewriting the PIPIN code to use a Monte Carlo solution approach
The objective of this project was to produce a Monte Carlo version of the third party activity model within PIPIN. There are currently limitations with the existing model and its FORM/SORM solution...
View ArticleRR1037 – Science updates to HSE’s PIPeline INtegrity model (PIPIN)
The aims of this project were to investigate the impact on the calculated failure rates as a result of changes to the science within PIPIN. The changes had been suggested after the model was...
View ArticleRR1038 – Data updates to HSE’s PIPeline INtegrity model (PIPIN)
The objectives of this project were to investigate the impact on the calculated failure rates as a result of changes to the data within PIPIN. These changes were required to ensure that the input data...
View ArticleRR1039 – Summary of the rewrite of HSE’s PIPeline INtegrity (PIPIN) model
This report summarises all three aspects of the model updates (solution method, science changes and data updates) and provides an overview of the results obtained compared to the original version of...
