The CORTIR Project

Cost and Risk Tool for Interim and preventive Repair (jr. nr. 64018-0507)

The project aims to cope with the various challenges of the appropriate maintenance strategies of wind turbines blades’ structural related issues. A Cost and Reliability Tool (CAR Tool) will be developed on basis of state-of-the-art research. 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. ​The CORTIR project is supported by the Energy Technology Development and Demonstration Program (EUDP), which is administered by the Danish Energy Agency.

Motivation

When damages and failures occur on wind turbine blades, it is semi-unexcepted and often outside the operational budget. The associated costs for repair actions often end up as a dispute between WTOs, OEMs and insurance companies, and risk will increase with future up-scaling of blades.

The CAR Tool is designed to take in a various amount of user inputs, but also have some set default values. With these the CAR tool generate the most optimal maintenance strategy to help you lower your O&M costs.

Interim and preventive repair solution

When lightning hits the blade in the winter it often has to be stopped until it can be repaired, which is not possible in the winter. Therefore the turbine have to be parked into spring. In the CORTIR project a solution to keep the blade running until it can be repaired will be developed.
