Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for offshore construction, such as using conventional temporary multi-pile platforms or offshore construction vessels, are inefficient, costly, and prone to quality control issues due to environmental factors like tides, waves, and currents.
Innovation Solution
A rotating construction platform based on a monopile, featuring a rotary connecting mechanism with an upper and lower connecting tube and a rotary support structure, allows the platform to rotate and be positioned flexibly around the monopile, eliminating the need for additional piles and reducing platform size while maintaining construction scope.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional temporary multi-pile platforms are used for offshore construction, then construction can be performed around the monopile, but the platform requires continuous piling and disassembly to adjust position, increasing construction time and complexity
Solution Approach 1:
The platform is designed with a rotary connecting mechanism that enables dynamic rotation around the monopile. The rotary support structure allows the platform to change its angular position continuously, transforming the static platform into a dynamic system that can adapt to different construction positions without disassembly.
Solution Approach 2:
The single-pile foundation serves multiple functions: it provides both the structural support for the platform and the central axis for rotation. This multi-functional design eliminates the need for separate positioning mechanisms and multiple piles, reducing construction time while maintaining adaptability.
2Adaptability or versatility
If a very large temporary platform with a hole in the middle is used to surround the entire monopile, then construction can be performed, but the platform size becomes excessively large, making the method technically and economically unreasonable
Solution Approach 1:
Instead of expanding the platform area in two dimensions to surround the monopile, the solution rotates the platform in the third dimension (angular position). This allows a compact platform to achieve extensive construction coverage by rotating around the monopile, effectively using angular space rather than linear space.
Solution Approach 2:
The platform is designed to rotate around and effectively nest around the monopile structure. The rotary connecting mechanism allows the platform to be positioned at different angular locations around the central monopile, achieving comprehensive construction access without requiring a large platform area.
3Productivity
If offshore construction vessels are used for construction around the monopile, then construction efficiency is improved, but the vessels are large in size, have tight construction periods, and require expensive equipment with proper configuration and fixing
Solution Approach 1:
The platform merges the functions of support structure and positioning system into a single integrated design. The rotary connecting mechanism combines the structural support function with the positioning adjustment function, eliminating the need for separate complex vessel systems and reducing equipment configuration complexity.
Solution Approach 2:
The platform uses the monopile structure itself as the central reference and support, copying the successful single-pile foundation design concept and applying it to the construction platform. This eliminates the need for separate vessel-based support systems and their associated complex configurations.
4Adaptability or versatility
If self-elevating platform vessels are used, then construction can be performed, but the vessels require plugging and unplugging leg piles and adjusting positions, resulting in low work efficiency and unreasonable technical economy
Solution Approach 1:
The platform employs a dynamic rotary connecting mechanism that allows continuous rotation around the monopile, eliminating the need for discrete plugging and unplugging operations. The rotary support structure provides smooth, continuous position adjustment, significantly improving work efficiency compared to stepwise position changes.

AI summary
The present invention relates to a rotating construction platform based on a single pile foundation, comprising a rotary connecting mechanism which is disposed on the top part of a single pile foundation and a working platform which is disposed on the rotary connecting mechanism. The rotary connecting mechanism comprises an upper connecting cylinder, a lower connecting cylinder, and a rotary support structure located between the upper connecting cylinder and the lower connecting cylinder. The working platform is fixedly connected to the upper connecting cylinder, the lower connecting cylinder is removably fixed to the top part of the single pile foundation, and at least one side of the working platform extends out of a side edge of the single pile foundation. The rotating construction platform of the present invention is stable and reliable, and can replace original methods which require the use of offshore construction work vessels or temporary construction platforms, improving the continuity of construction work, saving construction time and costs, preventing ship machines from being rocked by waves and hitting a single pile foundation when the construction space is small, improving the construction positioning accuracy, and ensuring construction quality.
