HAZOP can be done at any stage of a project as long as sufficient information is available such as piping and instrumentation diagram (P&ID). HAZOP can be revisited when there’s a design change impacting the P&IDs.Continue Reading

The bow tie risk assessment is a diagram method that can be used to analyse and demonstrate causal relationships in high-risk scenarios. The diagram is shaped like a bow-tie, creating a clear differentiation between proactive and reactive risk management.Continue Reading

Typically, the scope of the HAZOP is discussed in the document known as the Terms of Reference. This document will be passed to the attendees, along with marked-up P&IDs which indicates how the process is split up into nodes.Continue Reading
