Maintenance Strategy for Electrical Equipment Based on Integrated Operations

This paper presents a methodology to define a maintenance strategy for electrical equipment, including electric motors. This methodology is based on reliability-centered maintenance, and aims to ensure that the maintenance strategy results in maximum availability and efficiency of equipment and systems. The methodology is also compatible with the philosophy of integrated operations recently developed by the Norwegian petroleum industry to optimize the production from their mature oil fields. The first step is focused on the determination of the equipment criticality value. The paper proposes a methodology based on the Mudge method. Reliability criteria are adopted according to the criticality value. The maintenance intervals are determined considering the reliability criterion and the failure rate of each part of a motor. After determining criticality, the maintenance strategy and tasks are analyzed and determined based on failure modes and failure rates. To support this analysis, a procedure based on failure mode and effect analysis theory is used.
