ORS Consulting provides leading third-party integrity management solutions, including barrier strategy development, bow-tie analysis, risk-based maintenance, and Integrated Design Review (IDR). SERVICES Barrier Management Up Anchor 1 Barrier Management is a framework for the identification of major accident risks and continuous risk management throughout a complete asset lifecycle. Integrity management ensures that systems, operational procedures and organization perform their function effectively to avoid incidents and accidents. Integrity management comprises a variety of risk assessments, including barrier management, integrated design reviews, risk-based maintenance and obsolescence management. ORS Consulting is a leading third-party integrity management solutions provider. We are helping businesses and facilities perform barrier strategy development, bow-tie analysis, risk-based maintenance and Integrated Design Review (IDR), amongst others. Barrier Management Related Studies Barrier Strategy Development Barrier strategy development involves establishing a strategy for how a project or asset operation will manage the accident risk, and to ensure that barriers are designed and maintained to ensure an acceptable risk level. Bow-tie Analysis Bow tie diagrams are powerful tools for managing major accident hazards and communication of key risk drivers. It typically involves creating a bow-tie diagram, which illustrates the chain of causes and consequences related to a hazard, and its barriers and mitigating measures. Performance Standards Performance standards are requirement specifications established for barrier functions or elements, as input for design and operation of a system. Among others, performance standards can give requirements related to reliability, maintenance and operability. Risk-based Maintenance Risk-based maintenance (RBM) is a maintenance strategy that prioritizes risk-sensitive systems and machinery, applicable for all industries. An RBM helps businesses to plan maintenance processes based on the probability of failure, possible effects (consequences), and calculated costs. Barrier Management System Implementation Barrier management system implementation involves establishing and maintaining barriers in a facility so that risks can be managed and operational excellence can be achieved. It involves establishing technical, operational and organizational barriers against major accidents or incidents, and ensure that the barriers are maintained throughout the asset lifecycle. Optimization of Test Intervals The probability of failure of machinery or safety critical systems largely depends on the frequency of testing or preventive maintenance. Optimization of test intervals involves determining the optimum maintenance or test tasks that ensures high reliability, and at the same time minimizing downtime. Optimization of test intervals is typically performed in conjunction with performance monitoring of Safety Instrumented Systems. Obsolescence Management Obsolescence describes a situation in which a part, equipment, or service is no longer available even when it is still needed. Obsolescence management helps organizations to forecast, monitor, and plan when they are at risk of having obsolete parts, service, or equipment. It helps to reduce the risks associated with obsolescence. Root Cause Analysis Root cause describes a factor that caused a non-conformance in a system, component, or organization. A root cause analysis (RCA) is a problem-solving process that is used to identify these factors and provide approaches to preventing them. It may also provide a means of responding to them. Integrated Design Reviews (IDR) Integrated Design Review (IDR) is a method used to scrutinize project interface and is efficient for projects and assets with multiple stakeholders. This methodology focuses on the functionality of an integrated facility, and it aims to mitigate risks and ensure safe and efficient operations in these facilities. Risk-based Inspection (RBI) Risk-based inspection (RBI) involves quantitative and qualitative assessment of the probability of failure, possible consequences, and costs associated with systems and machinery. The information obtained from this assessment helps businesses to determine design flaws and potential damages, as well as the location of possible dangers resulting from failures.

SECTORS LIFE SCIENCE ORS Consulting supports the life science sector with specialist engineering, process safety and risk management services across pharmaceuticals, biotechnology, and other highly regulated process industries, including food and distilled spirits. ORS brings experience across multiple sectors, supported by well‑established risk management practices, such as oil and gas. We recognise both the parallels with, and the important distinctions from, these industries, and our goal is to deliver rigorous risk management that is genuinely suited to the operator’s risk profile and maturity. How do We add Value? ORS delivers a comprehensive range of process safety and compliance services across the life science sector, from initial hazard assessments to compliance related support and integrated advisory for operational phases. Our core service offerings include: Hazardous Area Classification: Risk assessments for facilities handling flammable substances, as well as development of Hazardous Area Classification drawings, zone schedules, and ignition source registers. The work also includes supporting clients to comply with relevant regulations such as ATEX directives, DSEAR (UK), etc. Process and functional safety : ORS supports clients with process safety studies from the initial HAZOP in concept stage until detailed design, including the link to further SIS lifecycle activities further down the line, such as SIL allocation, SRS, SIL compliance, in accordance with IEC 61508 / IEC 61511. Regulatory Compliance Support: Many life science facilities hold Seveso/COMAH-listed substances above threshold quantities, carrying defined legal obligations. ORS supports operators preparing necessary documentation for audits and new expansions, e.g., by conducting HAZID, updating consequence modelling, etc. Reliability, Availability & Critical Spares: RAM analysis and FMECA for production-critical equipment. Unplanned downtime in life science manufacturing carries significant commercial and reputational consequences as the sites are often classified as socially critical infrastructure. ORS support operators in identifying reliability vulnerabilities, defining critical spares requirements, and structuring maintenance regimes to safeguard production performance. Process Safety Training: To build genuine process safety competence within our clients' organisations, ORS develops site-specific process safety training for teams at all levels, from shift operators to senior management, focused on building genuine competence within process safety. Read more about our experience within the Life Science sector below Pharmaceuticals The pharmaceutical and biotechnology industries are governed by the Good Manufacturing Practice (GMP) framework, where product quality, patient safety, and regulatory compliance are inseparable from systematic control of technical and process‑related risks. Safety‑critical systems must not only function correctly, but also be documented, traceable, testable, and governed throughout their lifecycle. Failures, undocumented changes, or poorly controlled modifications to process, automation, or protection layers can lead to batch rejection, regulatory findings, or production shutdowns. Consequently, functional safety activities and process risk studies such as Hazard and Operability (HAZOP) and Layers of Protection Analysis (LOPA) studies must integrate seamlessly with GMP processes, including validation, deviation management, and change control. Some examples of project engagements Client: World-leading biopharmaceutical company, Denmark Project: Integrated advisory within functional safety, supporting the client from the hazard and risk assessment phase, SIL allocation, SRS, SIL Verification and auditing. Client: Specialised life‑science manufacturing company, Norway Project: Process safety and HSE support for a facility extension, supporting the client with early hazard identification, prepare and plan HAZOP activities, and manage environmental and operational risks alongside project execution. Spirit and Distilleries The distilled spirits industry handles flammable inventories at a scale that places squarely within scope for regulatory scrutiny. Whether you operate a single malt distillery, a large-scale grain plant, or a central blending and bottling facility, the obligations under ATEX (EU) / DSEAR (UK), Seveso/COMAH, and the associated HSE inspection are enforced. Process and functional safety are an effective way to support the distilled spirits sites in understanding and meeting their regulatory obligations. ORS delivers practical, site‑focused studies covering HAZIDs, HAZOPS, SIL/LOPA, ATEX/DSEAR, hazardous area classification and Seveso/COMAH, tailored to the realities of the distilled spirits industry. Some examples of project engagements Client: Ethanol production site, Sweden Project: Support with updating risk assessments as part of Seveso 5-year audit (including HAZID and consequence assessments), as well as training within the process safety domain. Food Industry Production of food is often not associated with hazardous substances; however, the supporting systems (e.g., cooling system) may consist of hazardous chemicals that can pose a risk for both personnel, quality, environment and asset. Understanding the key hazards contributing to the overall risk picture beyond the main process is essential for ensuring a safe plant. HACCP (Hazard Analysis and Critical Control Points) is commonly used in the food industry to identify, evaluate, and control food safety hazards throughout the production process. It addresses biological, chemical, and physical hazards and defines critical control points (CCPs) where control measures are required to ensure food safety. HACCP is recognised as a basis for food safety management within EU and international food regulations. Some examples of project engagements Client: Food producer, Norway Project: Supporting client with hazard identification and consequence modelling of the production plant.

Ensure your ICS and OT systems are secure with robust cybersecurity measures. Discover how ORS can help safeguard your operations and protect critical infrastructure from cyber threats. SERVICES ICS/OT Cybersecurity Up Anchor 1 As industrial operations become more connected, the risk of cyber threats targeting critical systems increases. Asset owners must ensure that their Industrial Control Systems (ICS) and Operational Technology (OT) are designed, maintained, and operated to minimize cybersecurity vulnerabilities. OT/ICS cybersecurity requires a structured approach to protecting industrial systems from cyber threats that could lead to safety or operational disruptions. It focuses on safeguarding critical infrastructure by implementing security measures to prevent, detect, and mitigate cyber incidents that could compromise industrial processes. In industrial environments, cyber safety plays a crucial role alongside cybersecurity. While cybersecurity broadly addresses the protection of data, networks, and systems, cyber safety specifically focuses on preventing physical harm, environmental impact, and operational hazards caused by cyber incidents. In industries such as oil and gas, chemicals, and manufacturing, where cyber threats can directly lead to fires, explosions, or equipment failures, cyber safety ensures that security measures align with safety-critical objectives. A key element of OT/ICS cybersecurity and cyber safety is ensuring the resilience of safety-critical systems. This includes Cybersecurity Risk Assessments (CSRA), defining security requirements, and implementing protective measures in line with standards such as IEC 62443. Cyber threats impacting safety systems, such as Emergency Shutdowns (ESD) or Safety Instrumented Systems (SIS), must be identified and mitigated to ensure safe and reliable operations. ICS/OT cybersecurity Related Studies initial cybersecurity risk assessment An initial cybersecurity risk assessment involves identifying and evaluating cyber threats to Industrial Control Systems (ICS). It defines the System under Consideration (SuC), assesses vulnerabilities, and determines the required Security Level Target (SL-T) based on risk. This assessment lays the foundation for implementing appropriate cybersecurity controls to mitigate risks to an acceptable level. Both applicable for legacy and new projects. Detailed cybersecurity risk assessment A detailed cybersecurity risk assessment builds on the initial assessment by performing an in-depth analysis of threats, vulnerabilities, and potential attack scenarios for the System under Consideration (SuC). It evaluates the effectiveness of existing security measures, identifies gaps, and determines specific countermeasures to achieve the required Security Level Target (SL-T). This assessment ensures a risk-based approach to cybersecurity, aligning protections with operational and safety requirements. Vulnerability assessment A vulnerability cybersecurity assessment identifies and evaluates weaknesses in Industrial Control Systems (ICS) that could be exploited by cyber threats. It involves analyzing system architecture, configurations, and known vulnerabilities in hardware, software, and network components. The assessment helps prioritize remediation actions to reduce exposure and improve the overall cybersecurity posture. gap/compliance assessment A GAP/compliance assessment evaluates how well an organization's security measures align with relevant standards or internal policies. It identifies deficiencies (gaps) in policies procedures, and technical controls compared to required security levels. Security level allocation Security level allocation involves assigning a required Security Level Target (SL-T) to Industrial Control System (ICS) components based on identified cyber risks. It ensures that each system, zone, or conduit meets the necessary security requirements to mitigate threats. This process aligns cybersecurity protections with operational and safety needs while maintaining a defense-in-depth approach. A Cybersecurity Requirement Specification (CSRS) defines the security controls and measures needed to protect an Industrial Control System (ICS) based on its identified risk and Security Level Target (SL-T). It ensures that cybersecurity requirements are systematically documented, similar to the Safety Requirement Specification (SRS) in IEC 61511 for functional safety.
