The aim was to rewrite MISHAP01 and PipelineRiskAT within a single program to facilitate the implementation of future improvements to the model.

RR1039 – Summary of the rewrite of HSE’s PIPeline INtegrity (PIPIN) model http://www.hse.gov.uk/research/rrhtm/rr1039.htm http://www.hse.gov.uk/research/rrhtm/rr1039.htm#comments Fri, 10 Jun 2016 11:00:53 +0000 HSE http://news.hse.gov.uk/?p=51738 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 PIPIN.

RR1038 – Data updates to HSE’s PIPeline INtegrity model (PIPIN) http://www.hse.gov.uk/research/rrhtm/rr1038.htm http://www.hse.gov.uk/research/rrhtm/rr1038.htm#comments Thu, 09 Jun 2016 14:00:51 +0000 HSE http://news.hse.gov.uk/?p=51736 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 was representative of UK pipelines by ensuring that all of the latest available information
was being used.

RR1037 – Science updates to HSE’s PIPeline INtegrity model (PIPIN) http://www.hse.gov.uk/research/rrhtm/rr1037.htm http://www.hse.gov.uk/research/rrhtm/rr1037.htm#comments Thu, 09 Jun 2016 09:30:32 +0000 HSE http://news.hse.gov.uk/?p=51734 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 independently reviewed.

RR1036 – Rewriting the PIPIN code to use a Monte Carlo solution approach http://www.hse.gov.uk/research/rrhtm/rr1036.htm http://www.hse.gov.uk/research/rrhtm/rr1036.htm#comments Wed, 08 Jun 2016 12:00:06 +0000 HSE http://news.hse.gov.uk/?p=51732 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 method and it was felt a new approach was required.

RR1035 – Update of pipeline failure rates for land use planning assessments http://www.hse.gov.uk/research/rrhtm/rr1035.htm http://www.hse.gov.uk/research/rrhtm/rr1035.htm#comments Fri, 03 Jun 2016 09:30:27 +0000 HSE http://news.hse.gov.uk/?p=51730 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 model. The historical failure rates used in the operational model are over 10 years old. A review took place to update this data.

RR1034 – Review of the event tree structure and ignition probabilities used in HSE’s pipeline risk assessment code MISHAP http://www.hse.gov.uk/research/rrhtm/rr1034.htm http://www.hse.gov.uk/research/rrhtm/rr1034.htm#comments Wed, 01 Jun 2016 10:00:36 +0000 HSE http://news.hse.gov.uk/?p=51728 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 response to the UK Onshore Pipeline Operators Association (UKOPA) challenging some of the assumptions and methods currently used within the tool.

RR1072 – Investigations into the immediate and underlying causes of failures of offshore riser emergency shutdown valves http://www.hse.gov.uk/research/rrhtm/rr1072.htm http://www.hse.gov.uk/research/rrhtm/rr1072.htm#comments Wed, 23 Dec 2015 10:00:37 +0000 HSE http://news.hse.gov.uk/?p=50521 Riser emergency shutdown valve (RESDV) failures, whether arising from a test or a real demand, are reportable to HSE under RIDDOR and a preliminary survey found approximately 180 cases of failure. Given the criticality of RESDVs to offshore safety, it was determined that the reasons for these occurrences should be investigated.
