Basic Technical Training Standard

Version 5
April 1, 2019

The Global Wind Organisation Basic Technical Training Standard consists of three modules and an additional installation module which can be taken after certification in the mechanical module.

Mechanical

The GWO BTT Standard Mechanical Module is designed so wind turbine technicians can:
  • Explain the main components, mechanical systems and the basic operation of wind turbines.
  • Explain risks and hazards associated with mechanics.
  • Understand the principles of bolted and welded connections and their inspection.
  • Demonstrate practical skills to use manual tightening and measuring tools.
  • Demonstrate the correct use of hydraulic torque and tensioning tools.
  • Explain the principles of a gearbox.
  • Explain the function of the brake systems and demonstrate how to inspect them.
  • Explain the function of the yaw system and explain how to inspect it.
  • Explain the function of the cooling system and demonstrate how to inspect it.
  • Explain the function of the lubrication system and demonstrate how to inspect it.

Electrical

The GWO BTT Standard Electrical Module is designed so wind turbine technicians can:
  • Explain the basics of electricity.
  • Explain risks and hazards associated with electrical work.
  • Explain the function and symbol of electrical components.
  • Explain the function of different types of sensors.
  • Explain and interpret a simple electrical diagram and demonstrate how to assembly it on a circuit.
  • Demonstrate how to make correct and safe measurements.

Hydraulics

The GWO BTT Standard Hydraulic Module is designed so wind turbine technicians can:
  • Explain the basics of hydraulics
  • Explain risks and hazards associated with hydraulic work
  • Explain the function of different types of pumps and demonstrate how to check start/stop pressure of a pump
  • Explain the function of different types of actuators.
  • Explain the function of different types of valves.
  • Explain the function of accumulators and demonstrate how to check and pre-charge them.
  • Explain the function of different types of sensors.
  • Identify the components which transfer the oil.
  • Describe the handling of oil procedures.
  • Identify and find different components on a hydraulic diagram.
  • Demonstrate how to measure the hydraulic pressure accurately.

Installation

The GWO BTT Standard Installation Module is designed so wind turbine technicians can:

  • Identify the main installation activities and explain the overallrisks and hazards associated with the installation environment
  • Explain the checklist systemthroughout the complete installation process
  • Explain the characteristics of the installation environment
  • Explain the principles and standards for handling and storing goods and components onsite or within a storage area before and after installation
  • Explain the basic principles of the lifting equipment
  • Explain the basic preparation of main components before installation
  • Explain the basic mechanical completion
  • Demonstrate how to perform the basic electrical completion including the principles and standards for handling and installing cables
  • Explain the basic hydraulic completion
  • Explain the principles of operating external generators during installation
  • Explain the basis of how to do a handover to commissioning

Effective date

After 31st March 2018, all new technicians working for GWO member companies and their suppliers are expected to complete the BTT Standard. Please ask your employer for more information.

Technicians with existing training from GWO member companies can have their skills merit assessed and where appropriate can be offered gap training to fill in any of the missed learning objectives.
