Wind Turbine Rescue Package Delivery Using Maintenance UAVs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high cost and logistical challenges of maintaining wind turbines, particularly offshore, due to the need for expensive rescue packages and frequent certification visits, which increase operational costs and pose safety risks.
Innovation Solution
Deploying an unmanned air vehicle (UAV) to provide a rescue package on-demand to wind turbines during maintenance operations, eliminating the need for standard equipment on each turbine and allowing for certification and equipment customization, reducing costs and improving safety by ensuring timely access to emergency gear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rescue package is provided as standard equipment on each wind turbine, then safety of maintenance personnel is improved, but operational costs increase significantly
Solution Approach 1:
The rescue package is pre-positioned on the maintenance vehicle before the maintenance operation begins. When needed, it can be rapidly deployed to the wind turbine without requiring permanent installation or separate certification visits, thus maintaining safety while reducing operational costs.
Solution Approach 2:
The maintenance vehicle serves multiple functions: it performs maintenance tasks and also carries the rescue package as a mobile safety station. This eliminates the need for dedicated rescue equipment on each turbine, reducing overall costs while maintaining safety coverage.
2Ease of operation
If a rescue package is provided on each wind turbine, then safety equipment is readily accessible, but certification requirements necessitate separate site visits increasing cost and time
Solution Approach 1:
The rescue package is merged with the maintenance vehicle, combining safety equipment with the already-necessary maintenance operation. This eliminates separate certification visits since the vehicle serving maintenance purposes also serves as the safety equipment platform.
Solution Approach 2:
The maintenance vehicle acts as an intermediary between the base and the wind turbine, carrying the rescue package during the maintenance operation. This allows safety equipment to be positioned at the turbine without requiring permanent installation or separate certification logistics.
3Reliability
If rescue packages are provided on all wind turbines, then safety coverage is comprehensive, but the cost of equipment and re-certification is significant
Solution Approach 1:
The rescue package deployment is dynamic rather than static - it is positioned on turbines only when maintenance operations require it, and can be relocated or retrieved by the maintenance vehicle. This dynamic approach maintains safety coverage when needed while avoiding the costs of permanent installation and continuous certification.
