Over the last thirty years, bowties have been widely adopted in almost all high hazard industries. In essence, the method is still the same as when Shell first facilitated extensive research and developed an initial set of rules and guidelines in the early nineties. However, the applications of the bowtie method and barrier management in [...]

A common mistake for beginning bowtie users is to describe threats as failed barriers. For example: “Failure of X”, ‘Lack of Y” or “Absence of Z” etc. Our quick and dirty advice is usually to just rephrase the threat in a positive manner so that it fits the description of a barrier. “Failure of ABS” becomes [...]

2018-03-09T10:14:42+00:00Blog, BowtieXP|

Loss of containment could lead to fire. Having multiple barriers or controls between those events could give the impression that the operation is well-protected. But what if your barriers are dependent on each other? Many organizations struggle with the level of detail when defining barriers in bowtie risk modeling. For example: should barriers be fully [...]
