Basic Technical Training Standards Set By GWO – Our Guide

The Global Wind Organisation (GWO) came to be as a response to the need for regulation in the wind industry. The members and workers who make up this organisation are globally leading turbine owners and manufacturers. They share risk information and expertise to improve safety on an industry-wide basis. 

To minimise accidents and improve safety standards, every technician in the industry has to pass certain training courses. Just recently, all new technicians working for GWO member companies and their suppliers are expected to complete the Basic Technical Training or BTT Standard. The BTT Standard set forth by GWO now has three modules covered, plus an additional installation module. The installation module can be taken after certification in the mechanical module.

Below are the scopes of technical training that every aspiring wind turbine technician needs to know, learn, and undergo.


The GWO BTT Standard Mechanical Module is designed to focus on the main components, mechanical systems, and basic operation of wind turbines. Along with knowing how these mechanics work is knowing the risks and hazards associated with them.

Technicians are expected to understand the principles of bolted and welded connections and their inspection. They should demonstrate practical skills to use manual tightening and measuring tools. Additionally, they must demonstrate the correct use of hydraulic torque and tensioning tools.

Every wind turbine technician should be able to explain the principles of a gearbox, the function of the brake systems, the purpose of the yaw system, the role of the cooling system, and the function of the lubrication system. They should also be able to demonstrate how to inspect all of these. Passing the Mechanical Module indicates a sufficient understanding of these aforementioned items.



The GWO BTT Standard Electrical Module ensures that technicians are able to explain the basics of electricity as well as the risks and hazards associated with electrical work.

Aside from being able to understand the electrical work associated with the machinery, technicians should be able to explain the function and symbol of electrical components as well as the function of different types of sensors. They should explain and interpret a simple electrical diagram as well as demonstrate how to assemble it on a circuit. Finally, they should demonstrate how to take correct and safe measurements.



The GWO BTT Standard Hydraulic Module is designed for wind turbine technicians and covers the basics of hydraulics as well as the risks and hazards associated with hydraulic work.

Technicians should be able to explain the function of different types of pumps and demonstrate how to check the start or stop the pressure of a pump. They should know how to explain the function of different types of actuators and the different types of valves.  Furthermore, technicians must be able to explain the purpose of accumulators and demonstrate how to check and pre-charge them. 

The Hydraulic Module includes the identification of the components that play a role in the transferring of the oil. Technicians must be able to describe the handling of oil procedures and identify the different components on a hydraulic diagram. The module also requires technicians to demonstrate how to measure hydraulic pressure accurately.



The last of the four modules, the GWO BTT Standard Installation Module has been set in place so that technicians can identify the main installation activities and explain the overall risks and hazards associated with the installation environment. 

The explanation of installation should include the following: the checklist system throughout the complete installation process; characteristics of the installation environment; and the principles and standards for handling and storing goods and components onsite or within a storage area before and after installation. 

Technicians are also expected to explain basic principles of the lifting equipment; the basic preparation of main components before installation; and the fundamental mechanical completion. They should demonstrate how to perform the necessary electrical completion, including the principles and standards for handling and installing cables.

Finally, they should explain the basic hydraulic completion; the principles of operating external generators during installation; and the basis of how to do a handover to commissioning.


Wind turbine technicians work in potentially dangerous environments every day. It’s essential for them to understand the risks and components involved so that they deal with each situation appropriately. This minimises risks and ensures that technicians stay safe on the job.
