Hazard and Operability (HAZOP)
and Hazard Identification (HAZID) Studies
The HAZOP technique is used universally across high
hazard industries as a method of identifying hazards and
operability problems in new and existing plant. In a
“blame and claim” culture, companies are under
increasing pressure to have safety measures in place to
improve the protection both of workers and the general
public. HAZOP is a powerful tool in helping to achieve
this. It is a formal and objective process, where a
group of experts assesses the different parts of a given system
with the aid of "guidewords". The process ensures a systematic
and well documented evaluation of potential
problems/hazards.
Successful application of HAZOP requires the system
design to have been established in a fair degree of
detail. In the early stages of design (when insufficient
information is available for the full-scale HAZOP) it is
more usual to use HAZID, a high level version of the
HAZOP process which provides a systematic assessment of
a plant in order to identify potential hazards.
Egerton Consulting has provided Secretaries and Chairmen
to companies for a variety of HAZOP and HAZID Studies
across a wide range of sectors, including the oil and
gas industry, the rail industry, and the water industry.
Example: Gas Plant HAZOP
Studies
Client: Schlumberger
Egerton Consulting supplied HAZOP secretarial support
for studies of five systems that were to form part of a
Gas Plant with potential LPG extraction.
The systems analysed included an LP flare, liquids
handling, a vendor membrane dehydration unit, a vendor
liquids handling package, and a gas compression station.
