RR1040 – Rewriting MISHAP: The development of MISHAP12

Wednesday, June 15, 2016

To calculate the risks associated with major accident hazard pipelines in the UK a computer code, MISHAP01 (Model for the estimation of Individual and Societal risk from HAzards of Pipelines), is used. The aim was to rewrite MISHAP01 and PipelineRiskAT within a single program to facilitate the implementation of future improvements to the model.

RR1035 – Update of pipeline failure rates for land use planning assessments

Friday, June 3, 2016

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

Wednesday, June 1, 2016

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

Wednesday, December 23, 2015

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.
