Wind Turbine Blade Decommissioning via Compression Bundling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The decommissioning of large-scale wind turbine blades is resource-intensive due to their size, requiring multiple flatbed trucks and drivers for transportation, which is costly and logistically challenging due to the scarcity of recycling facilities and landfills.
Innovation Solution
A method involving cutting turbine blades into sections, compressing them into manageable bundles using a compacting and bundling apparatus, and securing them with banding material to fit multiple blades onto a single flatbed truck.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If turbine blades are transported as complete units, then blade integrity is maintained, but the number of transport vehicles required increases significantly
Solution Approach 1:
The turbine blade is divided into multiple sections through controlled cutting at specific locations (root section, intermediate sections, tip section). Each section is then independently compressed and bundled. This segmentation allows multiple blade sections to be loaded onto a single transport vehicle, reducing the total number of vehicles needed while maintaining the structural integrity of each individual section through proper bundling.
2Quantity of substance
If turbine blades are cut into sections, then the number of transport vehicles is reduced, but the complexity of the handling process increases
Solution Approach 1:
Multiple blade sections are nested within a single transport bundle. The sections are stacked and compressed together in a compact arrangement that fits within the constraints of a single transport vehicle. This nesting approach simplifies the overall handling process by treating multiple sections as a single unit during transport, despite the initial complexity of segmentation.
3Productivity
If turbine blades are compressed into bundles, then transport efficiency is improved, but the equipment required for compression becomes more complex
Solution Approach 1:
A compression apparatus serves as an intermediary device between the blade sections and the final bundled form. This apparatus includes compression plates and hydraulic or mechanical compression mechanisms that apply force to compress the blade sections into a compact bundle. The intermediary equipment enables efficient compression while maintaining a manageable level of complexity through standardized mechanical components.

AI summary
A method for decommissioning a wind turbine blade includes separating a root section of a turbine blade from a tip section of a turbine blade, and laterally cutting the tip section of the turbine blade into a plurality of separate tip subsections. Each tip subsection is cut along its length, flattened, deposited into a compacting and bundling apparatus, and compressed. The compressed tip subsections are bundled in the compacting and bundling apparatus with banding material to form a bundle. The bundle is removed from the compacting and bunding apparatus and loaded onto a transportation vehicle.
