Mastering Barrier and SECE Management Webinar - ORS Consulting Finished Introduction to Barrier and SECE Management Managing barriers and safety-critical elements (SECE) is crucial in preventing accidents and ensuring the safety of operations. However, the process of identifying hazards, analyzing barriers, and verifying their performance can be complex and challenging. WATCH REPLAY In this webinar, we will introduce the Barrier/SECE Management Framework, including Hazard identification, Barrier/Bowtie Analysis, barrier/safety strategy, and performance standards. We will also discuss the link/interface between SECE and CMMS and share our experience in constructing CMMS logic to manage barriers/SECE. Additionally, we will share our experience in verifying barriers in operation. Our presenters, Per Ståle, Katarina, and Terje, are experts in their fields and will share their insights and experiences with you.

System Reliability and Availability are a staple in most businesses. It is the probability that a component, part, system, or process performs correctly within a specified period. A reliable system is one that will function appropriately with a minimum need for maintenance or repair SERVICES System Reliability and Availability Up Anchor 1 Reliability is a staple in most businesses. It is the probability that a component, part, system, or process performs correctly within a specified period. A reliable system is one that will function appropriately with a minimum need for maintenance or repair Most systems in facilities constitute interconnected components, with each component playing its role and helping to achieve a performance level. A system reliability assessment allows businesses to identify weaknesses of these components and quantify the impact of their failures on the overall system or process. ORS is a leading system reliability solutions provider. We are helping businesses and facilities with a wide range of services, including uptime and availability assessments, Fault Tree Modelling, among others. System Reliability and Availability Related Studies FMEA/FMECA FMEA (Failure Modes and Effect Analysis) and FMECA (Failure Modes Effects and Critical Analysis) are methodologies used to determine potential failure modes in a system and provide corrective measures for each failure mode. FMECA is similar to FMEA with regard to risk assessment and failure analysis. However, in addition to FMEA functionalities, FMECA ranks failure modes in order of severity. RAM Analysis RAM analysis is a method to define the production capacity and availability of a system to keep producing. This analysis involves a mapping of the different failure modes, frequencies, consequences, and their effect on production. RAM Analysis helps to reduce costs, debottleneck and provide input to spare parts and maintenance planning. Learn more > Production Assurance Production assurance describes the certainty of a facility achieving its production goals and meeting its intended end-results. End results may be customer expectations, the safety of a production process, or reduced production costs. Production assurance is particularly important within systems associated with oil and gas exploration and is introduced in ISO 20815:2008 standard. Fault Tree Modeling Fault Tree Modeling is a methodology used for conducting reliability analyses of complex systems. It involves creating a logical representation to model chains or pathways that can lead to failure or an undesirable loss event. It helps to keep systems safe and in desirable operating conditions. System Safety System safety is a risk management methodology that involves the identification and analysis of different hazards in a system, process, or facility. It also involves the provision of measures to eliminate or mitigate the effect of these risks. Among others, system safety is widely applied in the defence industry.

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.

Finished Essentials for confident and effective HAZOP participation 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.
