What's Wrong With HAZOPs?
HAZOPs are not as effective as they could be for several reasons:
- The focus on small nodes obscures the big picture.
- HAZOPs are supposed to identify operability issues, but there is no explicit consideration of operability in a typical HAZOP and no effective way to identify operability issues.
- The guidewords for a typical HAZOP are Flow, Pressure, Temperature, and Level. But flow deviations cause most pressure, temperature and level deviations. Discussing all four of the guidewords duplicates effort and causes tedium.
- HAZOP reports are difficult to read and therefore are not used for much after the HAZOP.
- HAZOPs are Not Fun! Most people don't enjoy HAZOPs and since they often run for days or weeks at a time, the resulting tedium impacts the effectiveness of the process.
- Risk assessment in HAZOPs is often difficult, ambiguous and not repeatable.
Stream-based HAZOPs address all of these problems.
