MAR Consulting prepared a scope of work and methodology report showing how a reliability, availability and maintainability (RAM) shall be performed for an offshore substation engineering project. The offshore substations will be receiving power from wind turbine generators and transmitting it to shore. MAR Consulting will eventually support the engineering team to develop the RAM model and analysis, depending on project award to Client. MAR Consulting has extensive experience performing RAM analysis in a variety of projects and industries. Please contact us if you need support on reliability, availability and/ or maintainability analysis.
MAR Consulting provided quality assurance (QA) and quality control (QC) of a Reliability, Availability and Maintainability (RAM) analysis of a turret and mooring of a Floating Production, Storage and Offloading (FPSO) vessel. The system consisted of a single point mooring and submerged turret production (STP), based on technology developed by the client. The RAM analysis documented the methodology and results in terms of production efficiency for the turret and mooring system.
MAR Consulting supported the development of a Reliability, Availability, and Maintainability (RAM) study for a new field subsea tie-back in the Norwegian Continental Shelf (NCS). The objective of the study was to provide the production efficiency (PE) estimates for the subsea field value chain in accordance with a revised base case and a high-level assessment for other three cases with different number of wells. In addition, a sensitivity analysis was performed for increased mobilization times due to no spare parts for the subsea production system (SPS), and subsea umbilical riser flowline (SURF).
MAR Consulting has entered a yearly agreement to provide support on-demand services to a gas operator in Norway. The services are related to the evaluation of production performance and regularity based on field modifications and implications to the gas network.
MAR Consulting supported the development of an availability study of a new concept for low voltage (LV) power supply to auxiliary systems in offshore wind substations. The concept proposed includes less redundancy. Therefore, it is essential to understand how it may impact the availability of the LV wind power substation. The substation’s main objective is to transmit offshore wind power to the onshore grid. For this purpose, auxiliary systems are essential to maintain the substation operationally capable. Failure of power to auxiliary systems such as cooling pumps, etc results in the inability to transmit power to shore. It was concluded […]
MAR Consulting assisted a client in evaluating (satellite) communication link design solutions from operability, availability, and cost stand-point. The services of the communication link between the unmanned surface vessel (USV) are: Transfer payload data generated during seabed surveys or subsea inspections; Control and operate the USV, in emergency situations; Control and operate the unmanned launch and recovery system, in emergency situations; Control and operate the autonomous underwater vehicles, in emergency situations. The different services listed above have different requirements, such as data transfer capability and latency. MAR Consulting proposed several options to fulfill these operational requirements. We focused particularly on […]
MAR Consulting expertise was used to perform a safety analysis report (SAR) and SIL compliance verification of the safety instrumented functions on the topside drilling BOP stack. As part of this effort, a FMECA was performed for the BOP (FMECA of topside BOP and control system · MAR Consulting). NORSOK D-001 “Drilling facilities” and NORSOK D-010 “Well integrity in drilling and well operations” describe the well barriers used during drilling. Drilling BOPs require strategies and principles for design, operation, and maintenance since they are defined as part of a barrier. The objective is that the barrier will function as required […]
Introduction MAR Consulting facilitated and documented a Failure Modes, Effects and Criticality Analysis (FMECA) for a major operator, of a hydraulic and pneumatic control system in a topside drilling Blow-Out Preventer (BOP). The FMECA was part of the initiative to re-start drilling in a field in the Norwegian Continental Shelf (NCS). The BOP OEM updated the BOP with a shear boost upgrade, PLC upgrade, auxiliary readback pressure panels, and Managed Pressure Drilling (MPD) flowline function addition. Objective In addition to the failure analysis, the Safety Analysis Report (SAR) used the FMECA outcome to comply with functional safety rules and regulations […]
MAR Consulting AS had assisted on producing a reliability, availability, and maintainability (RAM) analysis of a floating production storage and offloading (FPSO) unit to be stationed in the Norwegian continental shelf (see the previous article here). The initial model in the front-end engineering (FEED) phase had the objective of estimating the production efficiency of the current configuration, providing insight on bad actors and basis for modifications to improve the production efficiency. Since then, the model was further developed to include further details during the design and detailed engineering phase. The objective is to provide a more accurate estimate of the […]
MAR Consulting facilitated and documented an FMEA of electrical and control systems of a major drilling contractor’s subsea BOP. Purpose of the FMEA MAR Consulting facilitated the failure mode, effects and criticality analysis (FMECA) based on the methodology described on international standard IEC60812. Since it also included analysis of diagnostic capabilities, it could also go by the FMEDA designation (failure mode, effects, and diagnostic analysis). However, the purpose was significantly different than most FMEAs. Typically, an FMEA evaluates a design with the objective to unveil its weaknesses (and strengths). As a result, this information can form the basis of a […]
