Computer-aided Applications in Process Plant Safety

HAZID is a state-of-the art knowledge-based system for hazard identification. It does this by emulating a well-established technique called HAZOP (Hazard and Operability Studies). However, it has a number of non-trivial improvements that can be made to it to make it more user-friendly and the results more assessable to the end-users. The project will aim to investigate and tackle as many as possible the following usability and acceptability issues:

1) Taking CAD input from different sources
2) Supporting the workflow of end-users
3) Allowing the user to specify a sub-set of a plant to analysed
4) Reducing the volume of output so that the user can easily identify what is important
5) Linking HAZID’s capability of qualitative hazard identification with systems that carry out quantitative risk assessment.
