Process Safety Consultancy Method Process Safety UK Consultants

=Method offers Process Safety Consultancy to support our clients in carrying out Hazard and Risk Assessment (H&RA).

Hazard and Operability Study (HazOp)

HazOp is a systematic technique for reviewing a process design to understand the hazards present and identify appropriate control measures.

Layer of Protection Analysis (LOPA)

Layer of Protection Analysis (LOPA) is a semi-quantitative method of risk assessment. It is used to analyse “high severity” scenarios identified during HazOp in more detail. (These are usually the events that could potentially cause a fatality or another incident of equivalent severity.)

LOPA is often used for “SIL Determination”, where a SIS Safety Instrumented System is required. In other words, LOPA is used to decide the reliability (SIL Safety Intergrity Level ) required from the SIF Safety Instrumented Function . Read more about LOPA.

Verification

Because Hazard & Risk Assessment is one of the lifecycle phases of the functional safety standard IEC 61511, the H&RA must be “verified” as part of compliance with the standard. The purpose of verification is to check that the work has been done correctly.

Functional Safety Assessment

All work done to deliver the lifecycle phases should be “assessed”. The purpose of Functional Safety Assessment is to check that suitably competent people were selected to carry out the work, and that it has been done in accordance with the relevant procedures and plans.

Human Factors Risk Assessment (HFRA)

A project to deliver a Human Factors Analysis (HFA) of selected pipeline receipt tasks at a pipeline terminal. The purpose of this study was to evaluate the appropriateness of the use of the (industry standard) figure of 0.01 applied to human reliability or probability of failure within a recent LOPA Report. Through application of the HEART+ (Human Error Assessment and Reduction Technique) a study on the Human Factors (HF) aspects associated with the pipeline receipts tasks was undertaken. This provided a figure for human error; the assessed nominal likelihood of failure, which could then be directly used in the LOPA study in place of the generic data previously used.
