Process Hazards Analysis

Mustang’s Technical Safety Engineering group has extensive experience facilitating and scribing numerous forms of Process Hazards Analysis (PHA) for refineries, chemical plants (numerous processes), oil & gas facilities, pulp & paper projects, gathering stations, pumping stations, and pipeline transmission facilities.

PHAs are conducted using client procedures when available; however, project specific procedures are prepared when required. These procedures are in compliance with applicable regulations (EPA RMP Program, OSHA 1910.119, NFPA, HSE UK, NORSOK)

Reports are prepared to meet the documentation requirements of the above referenced regulations, providing a clear auditable record of the proceedings.

Mustang uses a number of software tools for reviews including PHA Pro, PHA Works, ePHA, and in-house developed Excel tool.

As in in-house resource, the Technical Safety Engineering group has access to the project team to allow for efficient review planning, which in turn streamlines the PHA process and adds value to the project.

The Technical Safety Engineering group can provide support for hazard action tracking registers, close-out procedures, and final close-out documentation that is “fit for purpose” on each project.

Examples:

• Formal P&ID Reviews
• Hazard Identification Assessments (HAZID)
• Hazard and Operability Studies (HAZOP)
• Safety System Functional Analysis (SSFA) / Safety Integrity Level Assignment (SIL), using qualitative as well as quantitative Layer of Protection Analysis (LOPA)
• API 14J Assessments

Environmental Studies

Representative studies include:

• Flare, Vent, and Exhaust Impact Study
• Greenhouse Gas and Emissions Study
• Effluent Discharge and Waste Management Study
• Smoke and Gas Dispersion Study
• Environmental Impact Assessment (EIA)
• Environmental Hazard Identification (ENVID)
• Noise Studies

Formal Safety Assessments

Formal Safety Assessments (FSA) are qualitative and quantitative methods for assessing the risks to the facility from major accident hazards (MAH) such as fires and explosions, dropped objects, etc.

The Technical Safety Engineering group can perform these tasks in-house or coordinate the work with 3rd party consultants as required on projects.

Representative assessments include:

• Quantitative Risk Assessment (QRA)
• Fire and Explosion Risk Analysis (FERA)
• Escape Evacuation and Rescue Analysis (EERA)
• Dropped Object Analysis (DOA)
• Essential Systems Survivability Analysis (ESSA)
• Facility Siting Studies
