BOP FMECA update to API S53 5th Edition

MAR Consulting AS updated a Failure Modes, Effect, Criticality and Diagnostics Analysis (FMECA / FMEDA) of the hydraulic control and safety systems of a major drilling contractor’s subsea drilling BOP. MAR Consulting had performed the previous original FMECA / FMEDA based on API S53 4th Edition and the US Code of Federal Regulations (CFR). The new rig contract requires compliance with API S53 5th Edition and therefore warranted the update. And it is outside the Gulf of Mexico where the US CFRs are not applicable. This work is part of the partnership to develop a BOP digital twin and failure […]

FTA of subsea BOP control and safety system

MAR Consulting developed a Fault Tree (FT) and Analysis (FTA) on failures of subsea Blow-Out Preventer (BOP) components, equipment, and systems. The probabilistic study made use of the developed fault tree and industry reported failure data (JIP RapidS53). The failure data used was collected in 2017-2018 from drilling rigs with BOP systems operating in the Gulf of Mexico. The main objective of the FTA of the subsea BOP was to develop a qualitative fault tree and use it to estimate the probability of the BOP system being unable to secure and seal the well (top event). The output of the […]

FMECA / FMEDA subsea drilling BOP (electrical and hydraulic systems)

MAR Consulting facilitated and documented a Failure Modes, Effect, Criticality and Diagnostics Analysis (FMECA / FMEDA) of the electrical and hydraulic control and safety systems of a major drilling contractor’s subsea drilling BOP. This work is part of an extended partnership to deliver such a product to the entire fleet of drilling rigs and ships. Description of projects MAR Consulting has been involved as part of this partnership: FMEA of electrical and control systems in subsea BOP · MAR Consulting; FMECA of redundant subsea BOP deadman-autoshear · MAR Consulting; FMECA electrical and control systems in subsea BOP · MAR Consulting; […]

Safety Analysis Report (SAR) of topside drilling BOP

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 […]

FMECA of topside BOP and control system

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 […]

FMECA of redundant subsea BOP deadman-autoshear

MAR Consulting facilitated and documented a failure mode, effects and criticality analysis (FMECA) on a new hydraulic solution for a deadman-autoshear system of a subsea blow-out preventer (BOP). To improve the reliability of the safety functions provided by the deadman-autoshear system, a solution with additional redundancy to critical components has been proposed. This solution was analyzed following IEC60812 methodology before it is included in the BOP. The main purpose was to understand the true benefits of such a solution from a safety and reliability perspective.

FMECA of blow-out preventer hydraulic system

MAR Consulting AS facilitated and documented an extensive failure mode, effects and criticality analysis (FMECA) on the hydraulic system of a blow-out preventer (BOP). The methodology was based on IEC60812 but modified towards operability and functionality of the system in analysis. The main purpose was to utilize the experience and knowledge of the participants to produce ready-made in-service risk assessments of failures that can occur. All components and failure modes were systematically assessed during the 45-days workshop in Houston, USA. The resulting assessments are to be integrated into a built for purpose simulation software delivered by a third-party. The objective is to […]
