Overview

This course will develop your understanding of the bowtie risk assessment methodology and how to conduct a bowtie analysis effectively in process safety management and environmental or asset integrity scenarios. It will demonstrate how the bowtie methodology provides the right level of detail to facilitate understanding and risk-based decision making, without oversimplifying a process.

The course covers when and why you should use the technique, as well as its strengths and limitations. You will also explore other barrier-based risk management approaches and similarities with HAZOP/PHA studies. There will be practical exercises where you can develop your own basic bowtie in collaboration with others.

You will also explore primary and secondary uses of bowties; the potential benefits of adding metadata to bowties; the significance of barrier management; the relationship with operations and maintenance activities; the role that barrier failure has played in familiar incidents; and human and organisational factors in bowties. 

The course aligns with current industry guidance. It is platform neutral and does not favour any specific software.

There will be an assessment at the end of the course. Following successful completion, you will receive your certificate of attendance (see below).
