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 mode database for failure reporting to the authorities.
