Application of hazard & operability study to safety evaluation of electrical design for a major power system upgrade of oil & gas production plant

Hazard is evaluated for electrical design of a major system upgrade of Thailand oil & gas production plant. The primary technique for the hazard evaluation was a hazard and operability (HAZOP) study; this is a brainstorming approach conducted by a multidisciplinary team. The approach simulates creativity of the team members to generate new ideas. As a result of this study, numerous, qualitative recommendations have been made to electrical design the safety and operability problems out of the major power system upgrade. Among the recommendations are suggestions on protection and control strategy, materials of construction, process material releases, alternative design options, and maintenance of this power system upgrade.
