The Hamburg-based Global Tech I Offshore Wind GmbH has planned and built the 400 MW North Sea wind farm Global Tech I in detail and is responsible for the operation. In 2018, the company decided to implement the monitoring of the 80 wind turbines, each with a capacity of 5 MW (type Adwen AD 5-116), with the SR::SPC Predictive Analytics Software solution developed by STEAG Energy Services (SES). A total of 49 KPIs (Key Performance Indicators) per turbine and 3,920 grades were defined, which enable a very comprehensive assessment of the wind farm. To temporarily support the operations team in integrating the system into the maintenance process, the STEAG WINDcenter was initially commissioned for one year to carry out a qualified pre-analysis of the calculation results.
