End of warranty inspection
Typically, installing a new offshore wind farm comes with a 5-year warranty on the blades. Combined with the fact that most major damages are caused by structural failures under the surface, the extent of end-of-warranty inspection has a high impact on the blade performance and service prediction.
This project aims to develop a new inspection concept to be used after the 5-year warranty period. This includes development of a new-to-the world method to test the bond lines between the aerodynamic skin and the load-carrying structure as well as in the trailing edge.
CORTIR - (Cost and Risk Tool for Interim and preventive Repair)
The project aims to cope with the various challenges of the appropriate maintenance strategies. A Cost and Reliability Tool (CAR Tool) will be developed. The vision of this project is to make the decision-making process regarding maintenance decisions easier and to support the entire value chain on how to minimize risk, operation and maintenance cost.
RATZ - (Root Area and Transition Zone)
The aim of this project is to demonstrate and develop a retrofit solution, the Floor™ (a Bladena patent), for avoiding crack development due to edgewise loading of the blade. The project address a serious problem seen in the field, which pose an extensive operation and maintenance cost for the wind turbine owners.
