Process Hazard Analysis (PHA)

ERSG is well experienced in the full range of PHA methodologies that include: Hazard and Operability Analysis (HAZOP) , Failure Mode and Effects Analysis (FMEA) , What if/Checklist Analysis (SWIFT) , Preliminary Hazards Analysis , Fault Tree Analysis (FTA) , Event Tree Analysis (ETA) etc click to view PDF

Pipeline Risk Assessment (PRA)

Pipeline Risk Assessment (PRA) in addressing recent Australian regulatory initiatives, ERSG has developed pipeline IMP plans and transmission/ distribution/gathering/facilities risk management plans. click to view PDF

Hazard and Operability Analysis (HAZOP)

A HAZOP is a highly structured hazards identification tool. It is extremely basic in its approach and makes practically no assumptions. HAZOP methodology is so widely used that almost any PHA is also referred to as a HAZOP. With new designs, HAZOP’s should be carried out as late as possible in order for it to be as complete as possible. With an existing facility, the HAZOP can be used at any time. click to view PDF

Safety Integrity Level (SIL)

ERSG’s Risk Division offers a proven track record of helping our clients to achieve success in risk mitigation and is committed to providing industry professionals with constructive solutions to meet their risk assessment and risk management objectives. ERSG can provide the resources that you need to complement your existing project team. We will review the project and its goals at the beginning of the project to ensure that it provides the information, analysis and solutions that meet your needs. click to view PDF

Failure Mode and Effects Analysis (FMEA)

Failure Mode and Effects Analysis (FMEA) and Failure Modes, Effects and Criticality Analysis (FMECA) are methodologies designed to identify potential failure modes for a product or process, to assess the risk associated with those failure modes, to rank the issues in terms of importance and to identify and carry out corrective actions to address the most serious concern. click to view PDF

Fault Tree Analysis (FTA)

Fault tree analysis techniques were first developed in the early 1960's. Since this time they have been readily adopted by a wide range of engineering disciplines as one of the primary methods of performing reliability and safety analysis. click to view PDF

Event Tree Analysis (ETA)

An event tree analysis (ETA) is an inductive procedure that shows all possible outcomes resulting from an accidental (initiating) event, taking into account whether installed safety barriers are functioning or not, and additional events and factors. click to view PDF

Integrated HAZOP/SIL Study (HAZOP/SIL)

Traditionally, a HAZOP and SIL Assessment (either using the Risk Graph or LOPA methodologies) are two separate facilitated sessions, which produce two unique databases. SIL Validation is yet a third task that uses another set of tools and produces a third database. ERSG has developed an integrated approach using a sophisticated HAZOP / SIL tool, called Lihou™ that combines these three tasks into one tool and one database. click to view PDF

Layer of Protection Analysis (LOPA)

ERSG’s Risk Division offers a proven track record of conducting LOPA which is a semi-quantitative risk analysis technique. It lies in between a HAZOP and a quantitative risk assessment (QRA) in terms of its rigorousness. This technique evaluates risks by orders of magnitude of the selected accident scenarios and builds on the information developed in qualitative hazard evaluation. (e.g. PHA). click to view PDF

Process Safety Management System Audits (PSMSA)

Process Safety Management (PSM) systems audits are necessary to track and monitor safety systems and procedures implementation. PSM Systems Audits identify opportunities where systems can be strengthened. The PSM system has 12 major elements and many sub-elements that can guide the monitoring of the system. The progress should be periodically reviewed and improved. click to view PDF

Revalidation of PHAs

Revalidating your PHAs ensures that:  The initial PHAs are consistent with current practice, no process hazards are identified, adequate controls are in place to manage hazards, completeness of the initial PHA, consistency with risk rankings and compliance with applicable regulations. click to view PDF
