A Participant's Guide to the Process HAZOP: Essentials for confident and effective HAZOP participation. Finished Have you ever been invited to a HAZOP (Hazard and Operability Study) workshop and asked yourself: What is my role in this HAZOP and how can maximize the value as a HAZOP participant? If so, our webinar replay is an thing you do not want to miss. WATCH REPLAY The intention of a HAZOP is to evaluate a design or an activity with the primary objective of identifying potential hazardous events and assessing the safeguards in place to prevent and mitigate these events. The outcome of a HAZOP can prevent accidents from occurring - and a bad HAZOP can fail to identify design flaws and hidden hazards. Its success depends solely on the contributions of the participants involved. Watch the replay of this engaging webinar where two of our HAZOP facilitators, Rikard Davidsen and Morten Nilstad Pettersen, share insights on how to shine as a HAZOP participant and give examples of pitfalls to avoid.

SERVICES Chemical & Process Up Anchor 1 Chemical & Process Engineering involves the design, optimisation and operation of industrial scale processes for the safe manufacture of useful products and materials. From onshore chemicals production to offshore oil and gas, Chemical and Process engineers are at the heart of an organisations technical capability for delivery of business, safety and environmental performance. ORS have an expert chemical and process engineering team supported by a range of state of the art software tools and techniques to help our clients get the most from their assets. This includes activities are studies such as: ​ Development of process schemes and improvements to maximise production and ensure safe operation. Creation and management of Digital Twins, Shadows and Models using live plant data where available. Dynamic simulation of new or existing plants to improve performance and explore equipment, set-point and other design changes. Software: Aspen HYSYS; SLB Symmetry, Flaresim, PHAST, CFD & FEA (ANSYS) Chemical & Process Related Studies Heat & Mass Balance Development Development of process heat and mass balance through equipment selection and optimisation to maximise production and minimise energy requirements. Arange of process simulation software is available to complete this including Aspen HYSYS and SLB Symmetry. Equipment Optimisation Individual unit operation assessments completed to help improve performance and ensure business demands are being met. This can range from traditional vessel, valve and pump sizing/costing through to more advanced analysis to study local heat, mass, and momentum effects using CFD & FEA. Digital Twins Development of digital models which reflect the as-built condition of chemical and process plants to identify performance and profit improvements. These can be developed into Digital Shadows and Twins with the capability of updating set-points through DCS to realise improvements and business performance. Flare, Venting, Relief, & Blowdown System Performance Safe disposal of fluids in an emergency situation is an essential part of any process plant design. Hence flare systems are considered safety-critical. We use Flare System Analyzer and other industry-standard tools to ensure back-pressures, velocities, momentum, flare tip radiation, and low-temperature material design constraints are all met. Dynamic Process Simulation Dynamic simulation of a process plant behaviour to better understand the effects of failures and the ability of the design to safely address these failures. Overpressure Protection assessment Different combinations of instrumented and mechanical overpressure protection systems exist in all process plant designs. Vessel and piping design reviews, relief valve sizing and selection to the requirements of API 520/521/526, and reliability assessments of instrumented systems under IEC61511 are all necessary to ensure the system is suitably protected.

SERVICES Technical Safety and Risk Management Up Anchor 1 Technical risk management is the set of activities to identify hazards and assess and manage risks. Technical risk management is a fundamental part of all sectors and industries where incidents and accidents can cause harm to personnel, environment, asset, or reputation. The main activities within this area are:​​ Technical risk advisory throughout a project or asset operation to ensure that safety design minimizes harm to personnel, environment, and asset, and meets regulatory requirements; ​ Risk-based workshops for identification of hazards in a multi-discipline and collaborative environment; ​Performing risk analysis to establish risk picture, based on the frequency and consequence assessment, and benchmark with acceptance criteria. Technical Safety and Risk Related Studies Escape, EvaCuation, and Rescue (EER) Escape Evacuation and Rescue (EER) strategy and assessments ensure that a facility is designed and operated away allowing safety for personnel during the evacuation, availability of muster areas, the quick rescue of personnel, and controlled evacuation. Quantitative Risk Assessments (QRA) A QRA is a method to calculate and evaluate the frequency and consequences of the major accident hazards for a facility. The resulting risk picture is benchmarked with acceptance criteria and is efficient for ensuring a safe and robust design, as well as compliance with regulatory requirements. Gas Dispersion, Explosion and Fire Assessment Process plant layout and mechanical design need to be robust to minimize escalation if a loss of containment occurs. ORS has state of the art software solutions and expertise for the assessment of dispersion, explosion, and fire (pool, jet, and spray fires) and the ability to interface this with blowdown and flare assessment to minimize the likelihood of vessel rupture in the event a release occurs elsewhere on the plant Safety Case ​ A safety case is a demonstration of how health and safety hazards are managed for a facility. This requires systematic identification of hazards, evaluation of consequences and implementation of risk reducing measures to meet As Low As Reasonably Practicable (ALARP) principles. HAZID/HAZOP Hazard Identification (HAZID) and Hazard and Operability (HAZOP) studies are structured multi-discipline workshops in order to identify hazards for a system design, evaluate the consequences for safety, environment, and asset, and identify measures to reduce the risk. A HAZOP is typically performed for process systems with a potential for loss of containment. Learn more> EHAZOP/CHAZOP ​ Electrical Hazard and Identification (EHAZOP) is similar to HAZOP with regards to identifying hazards and operability issues. However, unlike HAZOP, EHAZOP focuses only on electrical systems. A Control Hazard and Operability Study (CHAZOP) covers programmable control systems (e.g. PLC and SCADA) and IT systems. SAFOP/SIMOPS A Safety and Operability Study (SAFOP) is commonly carried prior to operations to identify hazards, evaluate consequences and define mitigating mesures to avoid accidents and incidents. WHAT-IF WHAT-IF analysis is a structured analytic technique used to determine what systems, activities, operations can go wrong in a facility based on different scenarios. Based on the answers to the what-if questions, a facility can then judge the consequences of the activities that can go wrong. Environmental Risk Assessment (ENVID) An ENVID study helps facilities identify and manage risks related to harm to the environment. It is effective for analyzing waste storage and disposal, emissions, discharge of hazardous substances, as well as the environmental impact of operations. Learn more > Working Environment Health Risk Assessment (WEHRA) ​ A WEHRA study assesses the risks to the health and safety of persons working in a facility based on factors such as noise, vibration, illumination, harsh weather or exposure to chemicals or harmful substances. A WEHRA is efficient to identify measures to achieve an acceptable working environment.
