Description of the course
Target group
The Basic Technical Training modules are targeted at candidates who have no previous experience of hydraulic, mechanical, electrical or installation systems, or working with energy powered bolt tightening, but may also be used to upskill candidates who have some knowledge but not of its application in wind turbines.
Course Aims and Objective
The aim of the BTT Hydraulic Module is to give the participants the knowledge and skills to carry out basic hydraulic tasks (supervised by an experienced technician), using safe working procedures and the correct PPE.

After having successfully completed the BTT Hydraulic Module, participants will be able to:
  1. Explain the basics of hydraulics (Knowledge, intermediate level);
  2. Explain risks and hazards associated with hydraulic work (Knowledge, intermediate level);
  3. Describe the function of different types of pumps (Knowledge, basic level);
  4. Perform check of start/stop pressure of a pump (Skills, intermediate level);
  5. Describe the function of different types of actuators (Knowledge, basic level);
  6. Explain the function of different types of valves (Knowledge, intermediate level);
  7. Describe the function of accumulators (Knowledge, basic level);
  8. Perform check and pre-charge of accumulators (Skills, intermediate level);
  9. Describe the function of different types of sensors (Knowledge, basic level);
  10. Recognise the components that transfer the oil (Knowledge, basic level);
  11. Describe the handling of oil procedures (Knowledge, basic level);
  12. Recognise and find different components on a hydraulic diagram (Knowledge, basic level);
  13. Perform the accurate measurement of the hydraulic pressure (Skills, intermediate level).

The GWO BTT Hydraulic Module is approved by Global Wind Organisation (GWO).
