Risk & Process Safety Consultancy

The effective management of risk and process safety is one of the first priorities in any project. Production facilities, power stations, processing plants and renewables sites are usually complex and located in environments that can be hostile with potential for health and safety issues, negative environmental impact or loss-making downtime.

Restrata’s risk & process safety (RPS) team provides a comprehensive service for identifying, assessing and managing risks to businesses, industries and public sectors. The ability to predict, prevent or mitigate undesirable events is the single most important factor in achieving business success in industry.

The RPS team works hand-in-hand with our other service lines to ensure effective risk management is a key feature of every project throughout the lifecycle of the asset, from initial concept through full-scale production to decommissioning.

Restrata’s approach is multi-disciplinary and challenges conventional thinking. We encourage clients to approach project design from fresh perspectives and ensure pivotal decisions are based on a clear understanding of the integrity issues involved.

Specific areas of work Restrata undertakes include:
  • Risk mapping
  • Process safety
  • Regulatory compliance
  • Project safety and safety engineering
  • Operational safety
  • Reliability and availability analyses.

A Hazards and Effects Management Process (HEMP) provides a structured approach to managing the hazards and potential effects throughout the life cycle of an asset and its activities. There are a variety of techniques to conduct HEMP. Once determined, Restrata applies the appropriate technique, such as Hazard Identification (HAZID), Hazards Analysis (HAZAN), Hazards and Operability (HAZOP), Task Risk Assessment (TRA), Quantitative Risk Assessment (QRA) and Job Safety Plan (JSP). Hazard identification is the first and the most important step in risk assessment. If a hazard is not identified, it cannot be managed effectively. Restrata provides formal, systematic and comprehensive identification of hazards:

  • HAZOPs, HAZIDs
  • FMEA and FMECA
  • Plant surveys
  • Hazard registers and fault schedules
  • Risk ranking and risk assessment
  • Incident analysis and human factors reviews

Our extensive experience enables us to select the right technique to deliver the right results.

A health safety and environmental impact assessment (HSEIA) is an integrated assessment that considers the full lifecycle of projects, facilities and operations. It addresses the HSE impacts in each of the life cycle phases.

This formal assessment is a requirement in some jurisdictions and for some companies where no equivalent legislative requirements exist.

Qualitative

Engineering design requirements for hazardous facilities are becoming increasingly challenging, with organisations demanding the highest levels of safety integrity as well as higher production throughputs and greater flexibility.

Restrata undertakes skilled assessment to provide a robust demonstration of the adequacy of engineering designs and the effectiveness of safety systems. The aim is to provide a facility or operation with a level of defence that is proportional to the associated risk. Assessments can demonstrate that not all single failures will compromise the safety function and we ensure that best use is made of segregation, redundancy and diversity.

Quantitate

Formal safety assessments are increasingly being demanded throughout high hazard industries. Restrata’s approach delivers the required safety benefits where needed. The systematic identification and evaluation of the likely consequences and expected frequency of hazardous events is a major input to the risk management decision-making process.

Restrata has an established reputation in quantifying risk, from quick, coarse studies to detailed assessments. Many of our consultants have design, operations and management backgrounds, and their experience looks beyond the final numbers to interpret the results, communicate the implications and provide real and practical recommendations for improvement.

Safety Cases (Offshore) and Safety Reports (Onshore) demonstrate that major accident risks to an asset are As Low As Reasonably Practicable (ALARP). They are required by law in certain countries for onshore facilities processing or storing hazardous materials above specified threshold quantities and for onshore and offshore oil exploration and production. They may also be required by organisations operating within a self-regulatory regime.

Restrata has many years’ experience in developing safety cases or similar documents in line with legislation around the world.

The risks of damage to plant and interruptions to production must be managed alongside the risks to people and the environment. Both should be reduced in line with good risk management practice.

Restrata covers the following areas to ensure high levels of availability:

  • Plant is fit for purpose – Design Reviews and HAZOP
  • Facility has resilience to minor accidents – plant layout and/or fire and explosion protection
  • Plant control systems enable appropriate precautionary shut-down or recovery operations and avoid spurious trips – Reliability and Availability Studies
  • Key equipment is identified, tested and maintained regularly – RAM studies, Fault tree Analysis and SIL standards.

Any site which has the potential for major accidents usually has high capital value and the potential to cause large consequential losses. Insurance premiums can be high and some types of loss difficult to insure against. Transfer of some risks of financial loss can be part of a risk management strategy but only if the cost of transfer is lower than the cost of risk reduction. A professional risk surveyor’s inspection and report, preferably backed up with risk analysis to quantify potential loss and likelihood can provide the basis for negotiating reduced premiums, or in some cases enable insurance cover to be obtained. It may also inform the risk manager or insurance company on the levels of excess, re-insurance or exclusions to consider.
