Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Offshore floating wind turbine foundations face low power generation efficiency due to limited deck space, single turbine capacity, and interference between multiple turbines, especially when yawing for wind alignment.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple wind turbines are carried on a floating foundation to improve power generation efficiency, then the power generation capacity increases, but the mutual interference between turbines increases when yawing for wind alignment
Solution Approach 1:
The support frames are designed to extend upwards from the hulls at symmetric inclinations, creating a three-dimensional spatial arrangement that separates the wind turbines vertically and horizontally. This dimensional separation reduces the mutual interference between turbines during yawing operations while maintaining multiple turbines on the platform for improved power generation efficiency.
Solution Approach 2:
The support frames are symmetrically inclined away from the centerline of the floating foundation, creating an asymmetric layout relative to the platform's longitudinal axis. This asymmetric positioning optimizes the spatial distribution of turbines, reducing wake interference and improving overall power generation efficiency by allowing better wind flow between turbines.
2Object-generated harmful factors
If the distance between rotors is increased to reduce mutual interference, then the interference decreases, but the main size of the wind turbine foundation increases significantly
Solution Approach 1:
Instead of increasing horizontal distance between turbines, the support frames extend upwards at inclinations, utilizing the vertical dimension to separate turbines. This approach reduces mutual interference without significantly increasing the horizontal footprint of the floating foundation, thus avoiding a significant increase in the main size of the platform.
3Device complexity
If single-column or three-column floating foundations are used, then the structure is simple, but the deck space is very small and cannot accommodate a large number of devices
Solution Approach 1:
The floating foundation is divided into multiple hulls (at least two hulls spaced apart along the longitudinal direction), with each hull supporting its own support frame and wind turbine. This segmentation increases the overall deck space and accommodation capacity for multiple devices while maintaining relatively simple individual hull structures that can be independently constructed and assembled.
