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. |

 Interim repair solution

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.
CAR Tool
|
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 a 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.

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. |
LEX
The LEX project is a 3-year demonstration project started in July 2013 with a total budget of €4m whereof €2m are supported by the EUDP-programme. The aim of the project is to develop and demonstrate cost effective solutions for mitigating leading edge damages on blades for both existing and future wind turbines. |
