MAR Consulting developed a Technology Qualification Plan (TQP), according to DNV-RP-A203, for a new part of a multiphase meter (MPM). The plan shows that performance criteria and all risks identified during a Failure Mode, Effects, and Criticality Analysis (FMECA) workshop have been addressed by choosing and applying suitable qualification methods. The outcome of related activities shows no degradation of the overall MPM metering performance but a successful measurement decoupling from downstream piping configurations, as intended.
MAR Consulting performed an extended review and quality assurance (QA) of a layers of protection analysis (LOPA) report for a chemical plant in Germany.
MAR Consulting facilitated a mini-HAZOP (hazard and operability) and a LOPA (layers of protection) analysis of an open drain system in an offshore wind substation platform. Since the platform is normally unmanned and due to environmental conditions in the region (South Korea), the Operator prefers to discharge the open drain inventory to sea. The discharge shall be processed to avoid potential contaminants (such as transformer oils, foam from active fire protection, etc) to sea. Discharging to sea is an alternative to collecting the open drain in a sump tank and potentially requiring extra de-bunkering visits. The objective of the HAZOP […]
Introduction MAR Consulting facilitated a hazard identification (HAZID) workshop of topsides of three (3) offshore wind substations (OSS) platforms. The methodology was based on the guidewords from DNV-ST-0145 with addition of other relevant topics such as work environment related hazards. The HAZID of offshore wind substations covered the topside during the operational phase only. The substructure including the application of the structure as a system for supporting the topside and for transfer to / from a crew transfer vessel (CTV) were not assessed in this HAZID. Participation from the different engineering contractors, as well as the operator and a 3rd […]
MAR Consulting supported the Client in performing a fault tree analysis (FTA) for hazardous scenarios in an onshore chemical facility. The scenarios to be analysed were deemed too complex to be handled in a traditional layer of protection analysis (LOPA). LOPA cannot be used for scenarios with a multitude of initiating causes and different combinations of independent protection layers (IPL) for each cause. Fault trees are more flexible and can be used to model the probability of occurrence of such hazardous scenarios.
MAR Consulting was contracted to support with a layers of protection analysis (LOPA) of one module integration in a floating production, storage and offloading (FPSO) vessel. The project may require additional barriers to protect the new equipment to be installed. These barriers can be, among other options, safety instrumented functions (SIF). LOPA is one method to allocate safety integrity levels (SIL) to SIFs if additional risk reduction is necessary. The objectives of the LOPA/ SIL allocation were to: Verify if the existing barriers are sufficient, and the risk level is sufficiently reduced such that the tolerability criteria is achieved to […]
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.
Introduction MAR Consulting facilitated a Safety and Operability (SAFOP) workshop of the electrical equipment in an offshore wellhead platform for an ultra-HPHT (high pressure high temperature) gas condensate field located in the Central North Sea. The online workshop was attended by discipline experts from engineering contractors and subcontractors as well as the asset operator. The objectives of this SAFOP were to: Assess and minimize potential hazards to persons around or in the electrical installations; Provide a critical review of the electrical system design and equipment, assess any limitations and their effects on operability, safety and security of the system; Analyse […]
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 was contracted to examine an onshore LNG terminal in Norway. The objective of the day visit and inspection was to support a decision to invest from a potential buyer. MAR Consulting was sub-contracted by the engineering company responsible for the overall due diligence process.
