ORS is a leading provider of Process Safety and SIL. We are helping businesses and facilities with a wide range of services, including all lifecycles of functional safety management, HAZOPs, dynamic process simulations, process safety time assessments, and overpressure protection assessments. services Process Safety and SIL Up Anchor 1 Any process that handles hazardous substances has the potential for a loss of containment event that could lead to a significant incident. Asset owners need to ensure that the process equipment is designed, maintained, and operated to minimize the likelihood of this. Process Safety is a framework for ensuring that the process design envelope is protected and has resilience against system failures and degradation. Process safety consequently focuses on preventing or mitigating loss of containment scenarios that could lead to fires, explosions, and accidental chemical releases at process facilities. An important part of Process Safety is Functional Safety. The core of functional safety is about defining requirements for instrumented safety systems and so-called safety instrumented functions, which normally include an input device, logic solver, and a final element. ORS is a leading provider of Process Safety and SIL. We are helping businesses and facilities with a wide range of services, including all lifecycles of functional safety management, HAZOPs, dynamic process simulations, process safety time assessments and overpressure protection assessments. Process Safety and SIL ReLAted Studies HAZOP HAZOP is a structured, multi-discipline assessment of a process system to ensure that the risk for loss of containment is minimized and that the design meets process safety-related standards. Learn More> 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. Process Safety Time Assessment Ensuring that Safety Instrumented Systems can react within a suitable period following a process disturbance and avoid the design envelope from being exceeded. Steady-state and dynamic methodologies are used to meet IEC 61511 and ISO 10418 requirements. 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. 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. Functional Safety Management Plan The Functional Safety Plan describes the project plan, organization and principles to ensure functional Safety throughout the entire period of the project development and asset operation. A functional safety plan must state a set of measures to ensure that the target Safety Integrity Level (SIL) is achieved. SIL Allocation/LOPA SIL allocation, e.g. with Layers of Protection Analysis (LOPA) is a methodology for defining performance requirements for safety instrumented functions. In addition, the assessment can be used to evaluate whether adequate protection layers are in place to reduce risks to acceptable levels. SIL Compliance verification A SIL Compliance verification is applied to confirm that Safety Instrumented Functions (SIFs) meet the performance requirements, as detailed in the functional safety process. Such requirements include reliability requirements, architectural requirements as well as a demonstration of avoidance and control of systematic errors. Functional Safety Assessment (FSA) FSA is a third-party evaluation of the functional safety activities in a project, to confirm that standards (such as IEC 61508 and 61511) as well as Company requirements are correctly applied. FSAs are typically performed in steps depending on the phase and maturity of the project. The FSA prevents systematic failures and helps to ensure that functional safety is achieved in facilities. Safety Manual A Safety Manual is documentation provided by equipment or system suppliers justifying use in SIL-related functions. The intention with the Safety Manual is to provide input documentation for the overall SIL Compliance verification, and to demonstrate that the supplier organization, management systems and manufacturing process ensure sufficient reliability and minimizes systematic errors. SIS Performance Monitoring Safety Instrumented Systems (SIS) performance monitoring involves follow-up and benchmarking of SIS component failure frequency against design documentation and acceptance criteria. Among others, this can be used to adjust test intervals, improve test and maintenance regime or input to modification projects. Process safety training We support organizations with tailormade training courses within all aspects of process safety. For example, ORS has supported asset owners with SIL training for operators, functional safety management, technical safety, and planning / execution of Process Hazard Analysis. Proof test procedures Proof Test Procedures involve systematic testing of Safety Instrumented Functions (SIFs) to detect hidden dangerous failures that diagnostics might miss. These procedures ensure that sensors, logic solvers, and final elements can respond to hazardous conditions as intended, maintaining the required Safety Integrity Level (SIL) and optimizing maintenance intervals. Pre start-up safety reviews (PSSR) Pre Start-Up Safety Reviews (PSSR) are comprehensive evaluations conducted before initiating operations of new or modified equipment. The PSSR process verifies that all safety, environmental, and operational requirements are met, ensuring the facility is safe to start up. This includes reviewing documentation, field verification, and addressing any outstanding safety. cause and effects (c&e) The cause-and-effect diagram offers information about different causes and their trip effects on the field equipment. This document is used for e.g. emergency shutdown (ESD), process shutdown (PSD) and fire and gas systems (F&G) to identify various causes and their associated trips in a matrix style for better and simpler interpretation. Causes can include a change in the state of a digital input, a High High/Low Low alarm from an analogue input, and interlock logic. Effects can include i.a. tripping a motor or pump, closing a valve, opening a pressure relief valve or activating an emergency alarm.

Learn more about RAM ( Reliability, Availability and Maintainability) Analysis from ORS Industry Experts. SERVICES Reliability, Availability and Maintainability (RAM) Analysis Objective of RAM Analysis Reliability, Availability, and Maintainability (RAM) are system design attributes that can have a substantial impact on the lifecycle cost and performance of an engineered system. The purpose of RAM Analysis is to ensure high production performance while maintaining high safety and quality level in any given industrial operation. The objective of the RAM analysis is to provide decision support towards i.e.: Predicted production performance and project economics; Key production loss contributors; Maintenance strategy and spare part philosophy; Alternative technical or operational solutions (sensitivity studies); Main uncertainties related to production performance; Recommendations for improved production performance. Methodology for RAM Studies At its core, RAM studies entail representing a complex reality with a simplified model allowing for various types of analyses. Such a model can be used to predict performance and manage uncertainties. Results from the analyses should be used to give sound and unbiased decision support, as well as identify bottlenecks and main contributors to reduced performance and/or increased risk. 1.Establish Study Basis Identification of key assumptions and associated degrees of uncertainty is considered vital in order to effectively produce as realistic and accurate results as possible, and for giving input to sensitivity analyses that might be necessary to cater for uncertainties. The key assumptions will be documented in the RAM model study basis. Assumptions are typically categorized in technical, operational and analytical assumptions. Close cooperation with different disciplines in the project is necessary to ensure an understanding of the process and operation that results in a robust and realistic basis for the RAM model. Because of this, it is proposed to arrange for a work meeting or similar with relevant disciplines when establishing the RAM model study basis. 2.Required Input A good understanding of the system to be analyzed is important for the RAM analysis to obtain as accurate results as possible. Typical client input for RAM analyses include: System description; System schematics; P&IDs; Operational Philosophy. In addition to the above, one of the main premises for performing a successful RAM analysis is the use of appropriate reliability data. Application of data from literature and databases should always be thoroughly evaluated, to validate their relevance for the context in question. Reliability data sources include client experience data, OREDA and the PDS handbook. ORS has access to a wide range of reliability data sources. A Failure Mode, Effect and Criticality Analysis (FMECA) if available is also a good input for the RAM analysis, especially for complex systems to give an accurate basis for system modelling. 3.Establish RAM Model and Run Simulations The RAM model study basis is used to establish the RAM model, typically represented by reliability block diagrams (RBDs). The Monte Carlo method is normally used for the RAM model simulations to produce uncertainty ranges and confidence levels for the estimates. ORS uses the software Miriam RAM Studio for this purpose. 4.Analyze the Results The results from the simulation are analyzed and reported depending on the objective of the RAM study in the best way to create value to the client, ,with some examples shown below.

Learn more about the HAZOP study and why to perform it. ORS Consulting has extensive experience with facilitating and recording HAZOP studies. SERVICES Hazard and Operability Analysis (HAZOP) What is a HAZOP Study? Hazard and Operability (HAZOP) is the most widely used Process Hazard Analysis (PHA) technique. It provides a way of systematically identifying causes of deviations from a process design intention, which in turn reveals potential hazardous scenarios and allows understanding of them and how to prevent them from occurring. HAZOP studies are performed as multi-disciplinary brainstorming workshops. Why perform HAZOP Do you need a structured and detailed review of your process design to identify and manage process-related hazards? Then HAZOP is the optimal hazard analysis methodology. HAZOP studies are performed to: Methodically examine processes and operating systems to identify how they might deviate from the design intent; Prevent process-related accidents and incidents by evaluating process design with regards to safety (of people, the environment, or assets) and operability; Identify deviations from related standards and project requirements; Identify requirements for additional risk-reduction HAZOP studies are also great tools for the team to gain a higher understanding of the process and the available process safety documentation. HAZOP Study Methodology HAZOP studies are conducted as structured and multi-disciplinary brainstorming workshops to identify process-related hazards and operability issues, evaluate their consequences, and assess whether adequate safeguards are in place to prevent or control these hazardous scenarios. The HAZOP technique is based on the systematic use of process deviations composed of a combination of guidewords and process parameters. Examples of HAZOP study guidewords, parameters, and the corresponding deviations are shown below: Advantages of a HAZOP Study: The structured nature of the analysis ensures that hazards and operability concerns are identified and recorded in a thorough and systematic way. By applying guidewords meant for brainstorming the methodology allows for a consistent approach and ensures that all relevant aspects are considered and discussed. A well-conducted HAZOP serves as a robust foundation for further analyses and decision-making, including being the foundational block for Functional Safety. ORS Consulting has extensive experience with facilitating and recording HAZOP studies. Our principal consultants have extensive HAZOP experience for a wide variety of industrial applications. ORS combines technical knowledge and process know-how with experience and up-to-date competence related to relevant regulations and best practices (such as IEC 61882).

Learn more about what is Environmental Risk Assessment (ENVID) and why to perform it, from ORS Consulting Experts. SERVICES Environmental Risk Assessment (ENVID) What is ENVID? Environmental Impact Identification (ENVID) is a structured examination of environmental aspects for a facility for early identification of environmental concerns that may affect environment. The outcome of an ENVID is used to optimize the design and operational philosophy to minimize environmental impact. An ENVID is typically performed as a multi-discipline workshop. Why perform an ENVID? ENVID study is performed to; Identify acute or continuous sources of emission, discharge and waste for an asset or activity; Identify mitigating measures included in design to minimize environmental impact; Propose further mitigating measures to prevent, reduce or control identified sources of emission, discharge and waste; ENVID Study Methodology The ENVID study is carried out as a multidisciplinary workshop with participants from relevant disciplines and operational personnel. The workshop comprises of discussion of environmental hazards consequences, and typically including a coarse risk assessment for each hazard raised, practice and procedures and barrier elements (the corresponding control and mitigation measures). The ENVID review follows a methodology analogous to a Hazard Identification (HAZID) . The ENVID applies a set of guidewords suitable for identification of hazards and sources of emission, discharge and waste. Some examples of ENVID parameters and guidewords: Contact ORS Consulti ng to identify the potential environmental risks associated with your project.

Finished Flare System Dynamic Modelling - Approaches & Values This webinar from ORS will present the common approaches used to apply dynamic modelling techniques for Flare systems as well as benefits of undertaking such a study. The team will share experience obtained from previous projects undertaken for installations in the UK and Norwegian Continental Shelf. WATCH REPLAY Flare systems for offshore installations and onshore plants are a critical piece of equipment, which provide safe relief of inventory during both routine operations as well as emergency situations. Their design is often complex and comprised of multiple headers and sources from the entire complex, making it difficult to understand and predict their behavior. Dynamic modelling is a technique used to perform time-dependent analysis of a system, which can be applied to flare systems to investigate any potential operating or emergency scenarios and validate more traditional 'steady-state' assumptions. This is equally useful as a verification exercise for existing systems as well as during the design phase for brownfield modifications and can often result in significant CAPEX and OPEX savings on projects.
