The Need for CHAZOP
Since the early 1980s, there has been a continuing trend in the process industry to replace manual operations by automation, to centralise control rooms and to replace mimic and panel board representations with shared display screens. In addition, there is a trend to the use of networked filed I/O, the growing use of highly programmable and powerful “smart” field instruments, wireless field instruments, intelligent field control stations and Windows-based operator stations.

However, there is now the realisation, often through bitter experience, that the control design intention is not only difficult to specify unambiguously, but can be thwarted by the failure of the system in ways which were previously not possible with discrete panel-based controllers or hard wired relay systems. Major disasters such as Longford (1998), Texas City (2005) and Buncefield (2005) were all at least partly caused by control system problems.

The CHAZOP Technique
Building on the successful HAZOP technique, which has been used since the 1970s to improve the safe operation of chemical plants, CHAZOP provides a systematic, multi-disciplinary technique to improve the safety and operability of computer based control systems. The presenter co-developed this CHAZOP technique while working with ICI and Orica.

Four techniques are presented - the Preliminary CHAZOP, the System CHAZOP, the Loop CHAZOP and the Sequence CHAZOP.

The Course
Over two days, the course provides the students with in-depth background to CHAZOP, skills on successfully preparing for a CHAZOP and leading the CHAZOP sessions. Hands-on group exercises build skills, such that on successful completion the students will be able to begin leading CHAZOPs. The course is based on the successful ICI / ORICA CHAZOP leaders course that has trained dozens of CHAZOP leaders.
