The Development of Equipment Criticality Analysis (ECA) Protocols of Offshore Carbon Steel Static Mechanical Equipment
Keywords:Equipment Criticality Analysis (ECA), Risk-Based Inspection (RBI), DNV-RP-G101, Risk
Best practice in developing Inspection Plan for static mechanical equipment on offshore topside platform is by performing Risk-based inspection (RBI) analysis. However, there are hundreds or even thousands static mechanical equipment on offshore topside platform. Since detailed RBI analysis requires a lot of data and tedious calculation then it is necessary to do equipment criticality screening prior to perform detail RBI analysis as it is suggested in DNV-RP-G101. Equipment Criticality Analysis (ECA) protocols for carbon steel static mechanical equipment have been developed as criticality screening tools. The protocols were developed based upon DNV-RP-G101. ECA categorizes the static mechanical equipment into C1, C2, or C3 which refer to high, medium or low criticality equipment respectively. The C3 equipment will receive minimum surveillance with planned corrective maintenance while C2 and C1 equipment will require detail RBI analysis.
