The HAZOP study should preferably be carried out as early in the design phase as possible - to have influence on the design. On the other hand, to carry out a HAZOP we need a rather complete design. As a compromise, the HAZOP is usually carried out as a final check when the detailed design has been completed. I downloaded a couple of reviews on HAZOP from Mp3 Search Engine http://www.mp3hunting.com . Experts say almost the same...
