The Pitch In-House project, in which IKERLAN cooperates with the General Electric Company, has installed its first pitch system prototype in an offshore wind turbine. This development is located in the Østerild Wind Turbine Test Field, with facilities managed by the Technical University of Denmark (DTU) for testing technological developments.

In the framework of the In-House Pitch project, a tool is being implemented for the design and development of the main elements of pitch system of the wind generator, with elements for both power and storage. The pitch system is responsible for regulating the pitch angle of the generator rotor blades. 

This project began performing sizing tools in said system between 2012 and 2013. Based on the designed tools, between 2013 and 2015, the first prototype targeted at onshore wind turbines was developed. Over the last year, we made the leap to the development of the pitch system for offshore wind turbines, an area in which reliability and maintainability requirements are increasingly relevant.

Safety and reliability in this type of development is extremely important, taking into account the adverse conditions that must be faced by wind turbines located offshore and the current restrictions on maintenance. The In-House Pitch developed is currently in the process of certification.
