Column Platform Barrel Deck Integrated Module Construction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current column platform construction methods result in inefficient use of steel, increased center of gravity, and hindered inspection and maintenance due to separate module installations and lack of horizontal connections between modules.
Innovation Solution
An integrated structure construction method where modules are connected to form a unified bottom deck within a skylight opening in the barrel topmost deck, using on-site closing gap connection structures to combine the module-integration bottom deck and barrel topmost deck into a single integrated platform deck.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If modules are installed independently on the barrel topmost deck, then each module can be constructed and installed separately, but the center of gravity of the topside facilities increases and steel usage is wasted
Solution Approach 1:
The patent merges multiple independent modules into a unified integrated deck structure. The modules are connected through horizontal structures to form a single integrated unit that is then installed as one assembly on the barrel deck, eliminating the need for multiple separate installations and reducing the overall center of gravity.
Solution Approach 2:
The patent introduces horizontal connection structures that span between modules at multiple levels, creating a three-dimensional integrated framework. This dimensional approach allows modules to be structurally unified while maintaining their functional independence, resolving the contradiction between separate construction and integrated installation.
2Ease of manufacture
If modules are installed independently on the barrel topmost deck, then each module can be constructed separately, but the barrel deck requires sufficient anti-bending strength and stiffness which increases steel usage
Solution Approach 1:
The patent combines multiple modules into a unified integrated deck structure with horizontal connections at multiple levels. This merging creates a composite structure that acts as a single structural unit, distributing loads more efficiently and reducing the required steel section modulus of the barrel deck compared to supporting multiple independent modules.
Solution Approach 2:
The patent creates a composite structure by integrating multiple module units with the barrel deck through horizontal connection structures. This composite arrangement allows the modules and deck to work together structurally, improving overall bending stiffness and reducing the steel requirements for the barrel deck.
3Ease of manufacture
If modules are installed independently without horizontal connections, then installation is simplified, but the topside facilities cannot form a whole structure which reduces bending stiffness and increases bending stress
Solution Approach 1:
The patent merges independent modules into a unified structure through horizontal connection structures at multiple levels. These connections create a continuous load path that allows the entire topside facility assembly to act as a single structural unit, significantly improving bending stiffness and reducing bending stresses under wave loads.
Solution Approach 2:
The patent segments the topside facilities into modular units that are then reconnected through horizontal structures. This segmentation approach allows for simplified construction and installation of individual modules, while the subsequent horizontal connections restore the overall structural integrity and bending stiffness of the complete assembly.
4Ease of operation
If modules are installed independently with separate access systems, then each module can be accessed independently, but space and materials are wasted due to duplicate stairways and passageways
Solution Approach 1:
The patent designs shared horizontal connection structures and passageways that serve multiple functions: they provide structural integration between modules, create unified access routes, and establish communication pathways. This multi-functionality eliminates the need for duplicate access systems while maintaining independent module accessibility.
Solution Approach 2:
The patent combines access systems into a unified network that serves all modules. Instead of providing separate stairways and passageways for each module, the integrated structure provides shared access routes that can be used to reach any module, reducing material consumption and optimizing space utilization.

AI summary
A construction method for a column platform barrel deck and topside facilities, and a column platform. The construction method includes: prefabricating topside facilities in form of modules one by one, lifting each module to a predetermined position on the topmost deck of the upright barrel, and then connecting the modules to each other and forming a module-integration bottom deck at the bottom; during construction of the upright barrel, a skylight opening is reserved on the barrel topmost deck for the installation of the topsides, and the skylight opening allows the modular-integration bottom deck to be placed inside; an on-site closing gap is formed between the edge of the skylight opening and the outer edge of the modular-integration bottom deck perimeter; using the on-site closing gap connection structures to fill the on-site closing gap, so that the modular-integration bottom deck and the barrel topmost deck jointly form an integrated platform deck.
