Wind turbine maintenance is now a global group and continues to evolve as new machines provide services. Turbines that use conventional gearbox drive technology every year are potential candidates for major gearbox overhauls for many years.
It is estimated that 90% of turbine owners use refurbishment options during refurbishment to provide the same warranty and life expectancy as new gearboxes. As a rough guide, the cost of three standard refurbishments is the same as the cost of a new gearbox.

Various opinions about the flexibility of the gearbox. “People recognize that maintenance and repair are necessary because the turbine has been worn out for 20 years without wear,” said Soren Klyvo, CEO of the Danish company Mekanord, who has refurbished the wind turbine gearbox “usually the turbine should have a gearbox, It has been repaired 2-3 times during the 20-year lifespan, or you will get a new gearbox at the same cost. This is a broad procurement assumption,” he said.
In 2005, approximately 10 GW of wind turbines with gearboxes were put into use worldwide, which was approximately 13 GW in 2006. These machines will receive much attention in the next few years. In addition, it will reach 5,000 gearboxes next year and is expected to increase to 6,000 in 2013. In addition, in 2010, a total of 32 Gigabit transmissions were put into use worldwide, and 16,000 gearboxes must be modified by 2017-2020.
At the same time, a 7 GW turbine equipped with a gearbox was installed in Europe alone, requiring 3,500 refurbishments. However, some well-known European companies offer high quality and comprehensive refurbishment with at least 200 gearboxes. Therefore, a large number of expansion facilities are required.
Transmission repair companies are usually divided into four categories of business. The first is a small workshop for repairing old and small local turbine gearboxes. Secondly, in order to carry out more comprehensive transformation, there are some medium-sized independent companies, such as Danish marine Industrial gearbox repair gearbox expert Mekanord.
