A survey of faults on induction motors in offshore oil industry,petrochemical industry, gas terminals and oil refineries

摘要

The report presents a survey of the reliability of squirrel cagenmotors on board drilling, production and other platforms offshore,ntogether with cage motors in the petrochemical industry, gas terminalsnand refineries onshore. Most of the activity in this connection isnrelated to the North Sea that offers a tough environment for motors. Thencollected data have been treated statistically, and the faults sortednaccording to supply and motor data, driving conditions, maintenance andnso on. Comparisons between this survey and a survey from the IEEE havenbeen carried out. The report also pays some attention to methods fornmonitoring of machinery and detection of faults
