Key objectives of the course :

1.Understand the fundamental principles of power transmission couplings, used in rotating equipment such as centrifugal pumps

2.Provide opportunities for hands-on experience with shaft alignment

3.Be able to adopt safe working practices at all times when working with power transmission couplings

4.Understand and be able to identify typical failure modes for couplings.

Who Should Attend :

This course is directly relevant to those working in process plants using rotating equipment fitted with power transmission couplings-particularly including industries such as oil and gas, petrochemical, power generation, pharmaceutical, and waste and water treatment.

The course is aimed at end-user plant personnel responsible for the installation, operation, maintenance and reliability of rotating equipment, including those working in management, engineering, operations and technician roles.
