Overview

This training focuses on the early lifecycle phases of hazard and risk analysis up to, and including, the development of the Safety Requirements Specification (SRS) for process, oil & gas, petro-chemical and chemical industries according to IEC 61508 / IEC 61511.
This 5-day course comprises 4 days of classroom tuition and practical guidance, for understanding and mastering the application, of process hazard analysis and associated risk analysis as required for the early lifecycle phases of Edition 2 IEC 61508 & Edition 2 of IEC 61511 for SIS. We also include many fundamental topics that we know you need to understand, but are not covered in the standards. Practical exercises will be performed throughout the course based on real-life examples. There is a 5-hour competency examination on the last day.

Who Should Attend

Process Engineers, Instrument Engineers, Process Safety and Operations personnel who are involved in maintaining the integrity of their processes, and are more involved in the early lifecycle phases of functional safety management.

Key Learning Objectives

The topics cover the concepts of identifying hazards using tools such as What-If, Failure Mode and Effect Analysis (FMEA) and HAZard and OPerability (HAZOP). This will be further developed into the analysis of risk and methods of risk reduction to consider the effectiveness of preventative and mitigating layers of protection. The use of preventative safeguarding efficiencies will be introduced for use with the PHA Matrix, along with the advantages/disadvantages of using the PHA Matrix with different Hazard Analysis methods.

The different questioning techniques used by a Hazard study leader to guarantee a systematic study methodology are investigated, as is the HAZOP flowsheet design, by considering the use of the HAZOP for specific needs such as LOPA. A LOPA exercise will actually be carried out from the output of the course HAZOP exercise. Consideration of constructing effective nodes will be examined and a better definition will be given to claims of double jeopardy.

The course will introduce participants to the use of Safety Integrity Levels (SIL) and SIL determination using internationally agreed methods for assessing and quantifying process risk and risk reduction requirements. Delegates will be equipped with the knowledge and methods for undertaking various types of qualitative, semi-quantified and quantitative risk assessments.

Practical exercises will be carried out for Semi-Quantitative methods such as risk graph and LOPA. The shortfalls of the quicker methods will be investigated to allow the analyst to appreciate the limitations of screening tools. The most popular semi quantified method, Layer of Protection Analysis (LOPA), will be explored in depth.

The effective use of Event Tree Analysis will be looked at in two different forms (Mitigation ETA and Traditional ETA). The course will focus on how ETA can be used to qualitatively support the analyst in mapping out the various consequences given various events with safeguard success or failure. Analysts can then select those events which generate consequences of interest for which FTA may be required.

Delegates will also be taken through the requirements for safety management and the framework of a Safety Management System (SMS) for achieving effective process risk management. Best practice for SMS will be investigated with the use of Bow-ties linking the Hazard and its safeguards to the SMS. An insight into how process safety KPIs can be used to better align engineering and management in the prevention of major accident hazards will be covered.
