In high-hazard industries like oil and gas, chemical processing, and energy production, safety is not a feature to be added—it is the fundamental principle upon which every design decision, operational procedure, and management system must be built. Formal Safety Assessments (FSAs) represent the rigorous, structured, and evidence-based methodology for ensuring this principle is realized. An FSA is not a single document or a checkbox exercise; it is an iterative, holistic process of identifying, evaluating, and mitigating risks throughout a facility’s entire lifecycle, from concept through decommissioning.
For a globally recognized provider of integrated engineering and risk management services like Cormat Group, FSAs are the cornerstone of our philosophy. They provide the analytical framework that transforms regulatory compliance into genuine operational integrity. By systematically examining potential failures and their consequences, we move beyond prescriptive rules to a performance-based standard of safety, ensuring that protection is engineered into the very DNA of an asset. This proactive approach safeguards human life, protects the environment, secures capital investment, and ensures business continuity.
The core objective of an FSA is to provide a comprehensive demonstration that all significant risks associated with a facility have been identified, are understood, and have been reduced to a level that is As Low As Reasonably Practicable (ALARP). This is achieved not by intuition, but through a disciplined process that:
Identifies Hazards: Systematically uncovers what could go wrong.
Assesses Risks: Quantifies or qualifies the likelihood and severity of potential incidents.
Evaluates Safeguards: Reviews the adequacy of existing or proposed risk control measures.
Recommends Improvements: Provides justified, actionable recommendations to further reduce risk.
Documents the Case: Creates a transparent, auditable record of the safety rationale behind design and operational decisions.
An effective FSA is a living assurance tool, referenced throughout the asset’s life for management of change (MOC) reviews, incident investigations, and safety case updates.
A comprehensive FSA is a mosaic of interlinked studies, each providing a specific lens on risk. Cormat Group synthesizes these components into a coherent, defensible safety argument.
These are the foundational, qualitative workshops that kickstart the FSA process.
HAZID: An early-stage, broad-brush review using guidewords to identify potential hazardous events (e.g., “fire,” “toxic release,” “dropped object”) and their causes and consequences.
HAZOP: A later, more detailed line-by-line examination of Process & Instrumentation Diagrams (P&IDs). Using guidewords like “MORE FLOW,” “NO FLOW,” or “REVERSE FLOW,” a multidisciplinary team systematically challenges the design to uncover deviations from intent that could lead to hazardous operability issues.
This assessment specifically analyzes the potential for and consequences of fire and explosion events.
Focus: Identifying leak sources, modeling flammable gas dispersion, calculating explosion overpressures, and simulating thermal radiation from jet fires or pool fires. This study directly informs the design and layout for Active and Passive Fire Protection systems and emergency response planning.
The QRA is the numerical backbone of the FSA, providing a probabilistic measure of risk.
Methodology: It combines:
Frequency Analysis: Estimating how often a loss of containment event might occur (using leak frequency databases).
Consequence Modeling: Using tools like Computational Fluid Dynamics (CFD) for Flammable and Toxic Dispersion Analysis to determine hazard ranges for fires, explosions, and toxic gas clouds.
Risk Summation: Calculating individual and societal risk levels, often plotted on F-N curves, to compare against risk tolerance criteria and demonstrate ALARP.
This analysis ensures that personnel can reach a place of safety in a timely manner during an emergency.
Focus: Evaluating muster times, assessing the availability and capacity of escape routes (considering smoke/fire impingement), and verifying the feasibility of rescue operations. It ensures that Temporary Refuge (TR) integrity and lifesaving appliance (LSA) provisions are adequate.
Critical safety systems must remain functional during the very emergencies they are designed to mitigate. ESSA tests this premise.
Focus: Assessing the ability of systems like Emergency Shutdown (ESD), Fire and Gas (F&G), deluge, and blowdown to withstand the effects of major accidents (e.g., explosion blast loads, fire heat radiation, smoke). This ensures that the facility’s last line of defense does not become its first point of failure.
The safe disposal of emergency hydrocarbon releases via flaring is a key safety function.
Focus: Modeling thermal radiation footprints to ensure exposure levels at occupied locations are within safe limits. Simultaneously, it assesses smoke and unburnt hydrocarbon dispersion to minimize environmental impact and ensure safe air quality during a blowdown event.
HAC is a preventive methodology to avoid ignition of flammable atmospheres.
Focus: Defining zones (Zone 0, 1, 2 for gases; Zone 20, 21, 22 for dusts) based on the likelihood of a flammable release. This study dictates the specification of certified Ex-rated electrical and mechanical equipment, forming a primary barrier against ignition.
This optimizes the detection and response to incipient fire and gas releases.
Focus: Using 3D modeling and performance-based criteria to determine the optimal number, type, and placement of flame, smoke, and gas detectors to ensure timely alarm. It also models coverage for firewater monitors and deluge systems, creating a coherent detection-and-suppression strategy.
This is the tangible outcome of the fire risk assessments—the engineered systems that prevent, control, and mitigate fires.
Active Fire Protection (AFP): Systems that require a trigger to operate (e.g., deluge systems, firewater pumps, gaseous suppression).
Passive Fire Protection (PFP): Inherent design features that contain fires and maintain structural integrity (e.g., fireproofing on steel, fire walls, blast walls).
Our strength lies not just in executing individual studies, but in weaving them into a seamless, iterative safety narrative.
Lifecycle Alignment: We initiate FSAs at the conceptual design stage (HAZID), refine them through detailed design (HAZOP, QRA), and validate them prior to operations. The FSA is updated throughout the asset’s life.
Data-Driven Synergy: Outputs from one study become the critical inputs for another. For instance:
Dispersion analysis from the QRA defines the hazard ranges for EERA.
Explosion overpressure from FERA sets the design load for ESSA and structural PFP.
Leak scenarios from HAZOP are the basis for F&G Mapping.
ALARP Demonstration: We facilitate the ALARP process by identifying risk reduction options, evaluating their cost and benefit, and working with clients to implement reasonably practicable measures, ensuring a defensible safety case.
Regulatory and Standards Compliance: Our FSAs are structured to meet the requirements of major international regulations (e.g., OSHA PSM, Seveso III Directive, Safety Case regimes) and standards (e.g., API, ISO, IEC, NFPA).
A Formal Safety Assessment is ultimately a testament to due diligence and engineering excellence. It is the process that asks the hard questions before an incident ever can. By partnering with Cormat Group for your FSA needs, you gain more than a suite of reports; you gain a holistic, integrated understanding of your facility’s risk profile and a clear, actionable roadmap to inherent safety.
We engineer confidence by systematically replacing uncertainty with quantified risk management. In doing so, we protect your most valuable assets—your people, your reputation, and your operational future—ensuring that safety is not just assessed, but assured.
