Solution Overview
Problem
Current semi-submersible floating platforms for marine wind turbines face challenges such as high manufacturing and maintenance costs, complex assembly processes, and limited scalability due to large column sizes and complex structural requirements, which complicate installation and maintenance.
Innovation Solution
A semi-submersible floating platform with an essentially triangular design featuring six columns, where the wind turbine rests on a central column, reducing column and joining element dimensions while maintaining stability and buoyancy, and incorporating a standardized configuration for easier assembly and reduced structural complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If traditional semi-submersible platforms use fewer columns (3-4 columns), then the column dimensions and structural complexity increase, but the manufacturing cost and assembly complexity worsen
Solution Approach 1:
The platform is divided into multiple standardized column modules (at least 6 columns) that can be manufactured separately and assembled systematically. Each column serves as an independent floating unit connected by standardized joining elements, allowing parallel manufacturing and reducing overall complexity.
Solution Approach 2:
The design changes the structural parameters by increasing the number of columns from 3-4 to at least 6, which fundamentally alters the load distribution and structural configuration. This parameter change enables the use of smaller, standardized column dimensions while maintaining platform stability and reducing manufacturing costs.
2Stability of the object's composition
If column dimensions are increased to maintain stability with fewer columns, then the platform achieves adequate buoyancy, but the lifting equipment requirements and installation complexity increase
Solution Approach 1:
The buoyancy function is segmented across multiple columns rather than concentrated in fewer large columns. Each column provides partial buoyancy support, and the collective arrangement of at least 6 columns achieves the required platform stability with smaller individual column dimensions, reducing lifting equipment requirements.
Solution Approach 2:
The design transitions from a fewer-columns configuration to a multi-column arrangement, changing the spatial distribution of buoyancy elements. This dimensional reconfiguration allows the platform to achieve stability through distributed support rather than concentrated mass, reducing the size and lifting complexity of individual components.
3Adaptability or versatility
If non-perpendicular connections between columns are used to achieve platform geometry, then the platform configuration flexibility increases, but the manufacturing standardization and assembly ease deteriorate
Solution Approach 1:
The platform uses homogeneous, standardized column modules with uniform dimensions and standardized joining elements. All columns are manufactured to the same specifications and connected using identical joining mechanisms, ensuring manufacturing standardization and assembly ease while maintaining configuration flexibility through the standardized modular design.
4Device complexity
If the platform uses larger column sizes to reduce the number of columns, then the structural simplicity increases, but the scalability and adaptability to different wind turbine powers decrease
Solution Approach 1:
The platform structure is segmented into standardized modular columns that can be configured in different arrangements. The modular design with at least 6 standardized columns allows the platform to be scaled and adapted to different wind turbine powers by adjusting the configuration and number of modules, providing both structural simplicity and scalability.

AI summary
A semi-submersible floating platform including six columns (CV, CL) arranged forming a triangle such that three vertex columns (CV) are arranged at the vertices of the triangle. Three side columns (CL) are arranged at the centers of the sides of the triangle. Each column (CV, CL) is connected by a joining element (B) respective to each of the adjacent columns (CV, CL). Further, a side column (CL) is configured to support the wind turbine (A). The columns (CV, CL) that do not support the wind turbine (A) have a weight configured to maintain the center of mass of the set formed by the platform (1) and wind turbine (A) in the vertical of the hull center of the platform (1).
