Hydrocarbon facilities have several thousand equipment of several types located in different process units. The typical disciplines are fixed equipment, machinery, electrical, instrumentation and control systems etc. The challenge that comes with this diversity of equipment is to operate and maintain them in a cost effective manner without compromising safety and to avoid unplanned shutdown.
Becht’s priority screening technique provides basis for assessing unit level and equipment level criticality for a particular facility. The unit level criticality helps leadership team to focus on units with high consequences and equipment level criticality helps with resource allocation for routine maintenance tasks. The equipment criticality also provides the basis for “Equipment Reliability Plan” scope generation. The comprehensiveness of an ERP usually relies on the criticality of equipment.
