2010 - Gas
The client had recently experienced a significant incident, that came following a number of operational problems. Prior to restarting the affected unit a fitness for service review was carried out to ensure that all known problems had been recognised and rectified. Andy was asked to lead the human factors element of the review, which involved a review of incidents, task and error analysis of critical tasks and a formal HAZID assessment. The result was a thorough documentation of the known issues and risks associated with the unit based on past experience, and a list of actions and recommendations. The main finding was that the vast majority of issues were related to the unit's design, and relatively few were related to the softer human factors issues.
