SERVICES TECHNICAL WORKING ENVIRONMENT Up Anchor 1 Technical Working Environment management is committed to establishing and overseeing conditions that promote health, comfort, and operational efficiency for all personnel throughout the entire facility lifecycle. This includes careful consideration of layout and design to ensure a safe and optimal functionality that comply with laws and regulations. This field is integral to every stage of a project, including the Concept phase, Front-End Engineering Design (FEED), and final execution. At its core, the technical working environment places the wellbeing of individuals at the forefront. It ensures that, during both operation and maintenance, workers’ tasks are fully considered in the final design. By adopting this approach, risks are not only identified but also managed proactively, safeguarding those working within the facility. Typically, depending on project scope, these factors are covered: Ergonomics (arrangement/layout/access), Human Factors Chemical substances Noise & vibration Biological agents Illumination Indoor climate Outdoor operations Radiation Psychosocial & organisational conditions Visual display units Job hazard Working Environment Advisory throughout the project lifecycle or asset operation to ensure that design solutions promote a safe and healthy workplace, minimise exposure to harmful factors (e.g., noise, vibration, chemicals, ergonomics), and comply with standards and regulatory requirements. Risk-Based Workshops for identifying working environment hazards in a collaborative, multi-disciplinary setting such as Working Environment Health Risk Assessment (WEHRA) and Chemical Health Risk assessment (CHRA), enabling early integration of human factors and ergonomics into design decisions. Performing Working Environment Analyses and Inspections to establish the risk profile by assessing exposure to physical, chemical, and psychosocial factors, benchmarking against acceptance criteria, and recommending mitigation measures Technical Working Environment risk related studies and typical deliveries WORKING ENVIRONMENT PROGRAM The Working Environment Programme is a structured plan to manage health and working environment risks throughout all project phases. It outlines objectives, activities, responsibilities, and documentation to ensure compliance with regulatory requirements and integration into the project’s HSE framework. The programme promotes interdisciplinary collaboration and systematic risk assessments, such as WEHRA, CHRA, and WEAL, to secure safe and healthy working conditions. WORKING ENVIRONMENT AREA LIMITS (WEAL) WEAL defines the maximum permissible exposure levels for working environment factors such as noise, vibration, lighting, and climate (air changes and temperature) in different areas of a facility. These levels are typically framed in concept- and study phase. It provides clear acceptance criteria to ensure that design and operational conditions protect personnel health and comply with regulatory requirements. WORKING ENVIRONMENT AREA CHARTS (WEAC) WEAC is a documentation tool in the form of a document containing charts for each room and each area on the facility. Areas that have the same working environment conditions may be represented by a single, typical WEAC. This chart provides an overview of the working environment requirements applicable to the specific area or room, covering factors such as noise, vibration, lighting, radiation, and climate (including air changes and temperature). It directly relates to WEAL (Working Environment Area Limits) by ensuring that each classified area complies with the defined acceptance criteria and exposure limits set by WEAL in the study phase. Opposed to the WEAL, the WEACs will include predicted values and as-built measurements. Additionally, any non-conformities in the specific area. The WEACS are intended to be regarded as live information during all phases of the project. WEACS are typically initiated in FEED phase and are updated through execution phase and finally completed with as-built measurements. This ensures that once an area is categorised, its design and operation can be verified against the correct acceptance criteria, creating a clear link between classification and compliance. WORKING ENVIRONMENT HEALTH RISK ASSESSMENT (WEHRA) WEHRA is a structured assessment used to identify, evaluate, and manage potential health and working environment risks which are introduced to a facility and its personnel. This assessment is conducted in all project phases and includes the important end-users. It focuses on major hazards such as ergonomics/Human Factors, chemical substances, noise, vibration, biological agents, illumination, climate, radiation, psychosocial, and recommends mitigation measures based on a hierarchy: eliminate or substitute hazards first, then apply technical and organisational controls, and use personal protective equipment as a last resort. CHEMICAL HEALTH RISK ASSESSMENT (CHRA) A Chemical Health Risk Assessment (CHRA) is conducted to identify, evaluate, and control chemical health risks to an acceptable level across all activities involving exposure to hazardous chemicals. This assessment ensures that risks are systematically identified, assessed, and managed in a proactive manner throughout operations. Typically, a CHRA is implemented in several phases during a project. Early identification enables organizations to address hazards and risks introduced by new chemicals, such as those associated with new equipment, thereby facilitating the creation of effective, safe, and healthy workplaces, and minimizing the need for modifications during subsequent operations. The CHRA process takes the form of a structured workshop involving experts such as occupational hygienists, who provide specialized knowledge and insights to enhance the identification and management of chemical health risks. 3D-model of working environment design 3D-model verification of working environment design should be carried out regularly throughout the design development process. During these reviews, the project team uses 3D models to assess whether the design meets working environment requirements related to for example layout and access, and to recommend modifications where necessary. This approach enables early identification of risks and opportunities for improvement, ensuring that layouts support safe and efficient operations. All findings are documented for follow-up and to drive continuous improvement of the working environment. OUTDOOR RISK ASSESSMENT An outdoor risk assessment evaluates hazards for tasks performed outside on the facility, considering factors like weather, exposure time, and frequency. Each activity is scored to determine its overall risk level and prioritise mitigation measures. This ensures compliance with safety standards and reduces risks from environmental conditions. HSE-Checklist equipment packages, new areas and physical inspections The HSE checklist in NORSOK S-002 is designed to ensure that suppliers and contractors systematically address working environment requirements during design, procurement, and delivery. This checklist ensures all critical HSE aspects, ergonomics, noise, chemicals, and layout, are addressed before equipment is accepted, reducing risk and ensuring compliance. The checklist is also used for inspection of new areas on a facility or during physical inspection of new equipment. Working Environment Status Report The objective of the Working Environment Status Report is to give a summary of the various working environment activities that have been undertaken during the execution phase. The report shall reference working environment analysis and reports conducted in the project phase.

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.

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.

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.
