We have not seen a drop in quality of the HAZOP (risk reviews) in projects lately. BUT, we saw a dramatic drop about 25 years ago; this occurred when lots of new folks (EPC companies especially) starting saying "Sure, we can provide that HAZOP for you." There was (and still is) little control of competency [...]
Our data differs. We have performed more than 11,000 unit-sized PHA/HAZOPs over the past 24 years; 1,000 of these have been new designs (projects, as you have focused on); the rest have been re-do of existing plant PHAs (because the project PHA/HAZOPs were so deficient). If you have a good engineering team then the team [...]
Our data on 11,000+ unit sized hazard reviews to date (using HAZOP, What-if, and variations) show that using a risk matrix detracts from brainstorming and does not improve the risk judgment of a multiple discipline team of process and operations with good to excellent expertise. If you don't have such a team, then you will [...]
