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 […]

FMEDA Deepwater drilling blow-out preventer

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

FMECA BOP subsea drilling safety system

CHAZOP of control system on electrical power plant

MAR Consulting facilitated and documented a 2-day computer and control system HAZOP (CHAZOP) and a what-if analysis for an electrical power plant in Aruba. Major upgrades to the control system (HMI, PLCs, and network) triggered the analysis, with the objectives to: ▪ Evaluate the control system design modifications with regards to safety and operability;▪ Eliminate or reduce the likelihood of accidents and incidents due to the control system design modifications;▪ Identify and recommend design improvements. A what-if/ CHAZOP is a systematic review of the design and operation of a control system. MAR Consulting conducted the study as a multidisciplinary workshop […]

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 […]
