Process Safety

HAZOP Study. Hazard and Operability study under IS 15656:2008 to find and reduce process hazards, with team training, a guidance handbook and a HAZOP tool for producing reports.

Hazard Identification and Risk Assessment (HIRA). Identification of plant hazards and risks, flagging significant ones that need action plans, and developing control measures, with plant personnel trained to take part.

Layer of Protection Analysis (LOPA). Semi-quantitative risk assessment of the hazardous scenarios found in HAZOP or HIRA. We define the initiating event and consequence, credit the independent protection layers (such as basic process control, alarms with operator response, relief devices, safety instrumented functions and dikes), compare the mitigated risk with your risk tolerance criteria, and recommend extra safeguards where the gap remains. LOPA also supports SIL determination for safety instrumented functions.

Quantitative Risk Assessment (QRA). Qualitative and quantitative risk studies to prevent incidents and limit environmental impact, with team training, site surveys and a risk assessment tool.

Failure Modes and Effects Analysis (FMEA). Reliability technique under IS 15550:2005 to identify potential equipment, process and system failures and their effects, with an FMEA tool and report.

Process Safety Management (PSM). Systematic approach to preventing releases of highly hazardous chemicals, including hazard contour mapping and dispersion modelling, review of process safety documentation, design controls and management of change, and legal compliance checks.

Gas Dispersion Modelling. Assessment of how hazardous gases from a facility could spread to surrounding areas, to support safety decisions and emergency response planning.

Life Cycle Reliability and Safety Engineering. Reliability and safety support across the whole life of a plant, from design to decommissioning: safety requirements and SIL determination and verification for safety instrumented systems (IEC 61511 / IEC 61508), reliability, availability and maintainability (RAM) studies, proof-test interval and spare-parts planning, FMEA/FMECA and failure data analysis, mechanical integrity and inspection planning, management of change, and periodic safety reviews of ageing assets.
