Course Description:

The high cost of maintenance has prompted many organizations to view the management of the maintenance function with more urgency. The increase in the size and complexity of the rotating equipment has resulted in maintenance being accepted as an important mainstream function in such companies.

This course provides the participants with the means to properly operate and support the rotating equipment in a way based on the good acquaintance with the modern technologies applied in this field. Trouble-shooting & forecasting break downs are inclusive

Course Goal:

To enhance the delegate knowledge, skills, and abilities necessary to give him some practical exposure to help maintain the rotating equipment in good operational conditions and cope with the emergency cases of breakdown
