"Angarsk Petrochemical Company" JSC: Response to operation of vibration analysis system COMPACS at GK-3 unit

COMPACS^® system has been operated at GK-3 unit of "Angarsk Petrochemical Company" JSC since 1995. Currently the system monitors 223 rotating equipment units.

The unit maintenance personnel uses the system data, thus preventing the equipment operation in developing defects conditions, timely reacting to all the changes and taking actions prescribed in the system expert messages. It is necessary to point out a high reliability of diagnoses. There are a few examples (March, 2013):

• N-32 unit of КК sector. COMPACS^® system has detected an increase of Ае and Ve parameters. Following the expert system readings, the maintenance personnel has detected a problem with an electric motor bearing fit, and the unit has been decommissioned for repair.
• N-3/1, N-9 units. COMPACS^® system has detected an increase of Ае parameter. Following the expert system readings, the maintenance personnel has taken actions on adding lubrication to the bearing. Consequently, the increased vibration has been eliminated, and the unit has started to operate in an "ACCEPTABLE" state.

COMPACS^® system implementation allows to carry out timely and purposeful repair and maintenance in real time, which plays an important role in accidents prevention.
