MAR Consulting facilitated and documented an FMECA of electrical and control systems of a major drilling contractor’s subsea BOP. Purpose of the FMECA MAR Consulting facilitated the failure mode, effects and criticality analysis (FMECA) based on the methodology described on international standard IEC60812. However, the purpose was significantly different than most FMECA workshops. Typically, external resources perform an FMECA to evaluate a design with the objective to unveil its weaknesses (and strengths). As a result, this information can form the basis of a cost-benefit analysis for design improvement opportunities. In this project, however, in addition to the above, the drilling contractor/operator will use […]

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 […]
