HAZARD AND OPERABILITY ANALYSES (HAZOP)--A Hazard and Operability
Study (HAZOP) is a structured and systematic technique for identifying
hazards or operability problems throughout an entire facility. It is a
procedure which examines the Piping and Instrumentation Drawings systematically,
section by section or line by line (depending on the level of detail required),
looking for inadequacies in design. A checklist of guide words is applied
to the process variables at each stage of the review to identify deviations
from normal operating conditions (Design Intention). By using the list
of guide words, all conceivable eventualities are covered. The list of
deviations is then examined to determine possible cause, resulting consequences,
and suggested action.
Typical aspects considered are normal plant operation, foreseeable changes
in normal operation, plant start-up and shut-down, suitability of plant
materials, equipment, and instrumentation, provision for failure of plant
services, provision for maintenance, safety, etc.
Following is a brief list of HAZOP studies conducted by Pace in the
past several years.
