MAR Consulting supported performing and documenting a Probability of Failure on Demand (PFD) calculation. Due to the addition of new wells to the offshore producing platform in the Norwegian Continental Shelf (NCS), an hazard analysis identified a potential overpressure scenario. The production header has mechanical protection (relief valves) and a Safety Instrumented Function as a redundant barrier. Hence, MAR Consulting calculated the average PFD for this low demand Safety Instrumented Function (SIF). The PFD, when compared to the required risk reduction for this scenario, is acceptable for a number of new wells.
MAR Consulting performed a functional safety assessment (FSA) stage 3 for an engineering contractor and equipment supplier to a subsea production system (SPS). The SPS will be installed and operated in the Norwegian Continental Shelf (NCS). The equipment designed by the engineering company constituted the boundary for the FSA. The equipment is similar to the SPS currently in production in the tie-in field. Hence, the FSA focused mainly on installation, commissioning, and validation activities. MAR Consulting acted as an independent assessor to the project. The objectives were to ensure the equipment is fit for the safety instrumented functions; and is […]
MAR Consulting will support the technical implementation of a barrier management system into a built-for-purpose tool. The contract is with a major operator in the Norwegian Continental Shelf (NCS). The main purpose of the cloud software tool is to document and provide an overview of the status of all barriers and respective performance standards at any time. In other words, the interactive tool provided constantly updated visualizations of barrier status. This is a step forward from the traditional static barrier management systems and documentation. Depending on the success of the initial pilot, the same tool will be deployed for the […]
MAR Consulting facilitated a cyber-security risk assessment for an operator of offshore assets in the Norwegian Continental Shelf (NCS). The assets shall comply with the strict Norwegian regulatory requirements. Petroleum Safety Authority (PSA) in Norway runs periodical audits to ascertain the level of IT security (among others) in the operating assets in the NCS. This work is part of an extended partnership with the operator to identify potential cyber-security vulnerabilities in their portfolio. Other assessments part of this work are: Cyber-security assessment of FPSO IT/OT systems · MAR Consulting; Cyber-security risk assessment of FPSO · MAR Consulting; Cybersecurity hazard identification […]
MAR Consulting performed a functional safety assessment (FSA) stage 2 for the operator of a subsea production system (SPS). The SPS will be installed and operated in the Norwegian Continental Shelf (NCS). The FSA also included the SIS lifecycle phases typically assessed in an FSA stage 1. The scope was the subsea development design and boundaries towards the topside on the host platform. The scope of the assessment excluded topside tie-in modifications. MAR Consulting acted as an independent assessor to ensure the design of the SIS meets the required risk reduction and is in compliance with the standards, Norwegian rules, […]
MAR consulting AS performed a functional safety assessment (FSA) stage 1 of a subsea riser less well intervention system. The system will have two SIL2 safety instrumented functions (SIF), based on the Norwegian Oil and Gas Association (guideline 070) and IEC standards (61508 and 61511): One emergency shutdown (ESD); One emergency quick disconnect (EQD). Following IEC 61508/61511 safety lifecycle, stage 1 covered: Hazard analysis; Allocation of safety functions to protection layers; Initial version of safety requirement specifications (SRS); Management of functional safety and verification and validation. Documentation was readily available to demonstrate compliance with functional safety requirements at this stage of […]
MAR Consulting will perfom a functional safety assessment (FSA) stage 2 of a subsea production system (SPS) bound to be installed and operate in the Norwegian Continental Shelf (NCS). The end client is the company engineering the SPS. The contract is in effect immediately. FSA stage 2 focus on the design and engineering of the safety instrumented systems (SIS). In this case, there are two autonomous independent SIS aiming at reducing risks to acceptable levels. Furthermore, MAR Consulting will ensure that the assumptions and actions identified on the previous FSA (stage 1) were verified and acted upon. In addition, the client requested […]
MAR Consulting facilitated a cyber-security risk assessment of the systems required to operate a floating, production, storage and offloading (FPSO) vessel. The FPSO is currently operating in the Norwegian Continental Shelf (NCS). It is required to adhere to the strict regulatory requirements in the country. Petroleum Safety Authority (PSA) in Norway runs periodical audits to ascertain the level of IT security (among others) in the operating assets in the NCS. The main objective was to draw on the collective experience and lessons learned to identify potential cyber-security hazards. Other objectives were to analyze and evaluate identified cyber-security risks and propose ways to prevent […]
MAR consulting AS performed a functional safety assessment (FSA) stage 1 of a new subsea production system (SPS) development in the Norwegian continental shelf. Hazard analysis, allocation of safety functions to protection layers, the initial version of safety requirement specifications, and management of functional safety were assessed.
