Engineering Contradiction Analysis
1Area of stationary object
If conventional subsea fluid conveyance systems are used, then fluid transport function is achieved, but the system occupies excessive space and has high installation complexity
Solution Approach 1:
The flow line is divided into multiple linear sections that can be geometrically arranged in parallel configurations. This segmentation allows the system to achieve the required fluid conveyance length while occupying less subsea space and simplifying installation operations through modular assembly.
Solution Approach 2:
The patent employs three-dimensional geometric arrangements of parallel linear sections, utilizing vertical and lateral spacing to optimize space utilization. This dimensional approach enables compact footprint while maintaining adequate flow line length and functionality.
2Reliability
If conventional complex designs are used, then high-integrity pressure protection is achieved, but manufacturing costs and testing requirements increase
Solution Approach 1:
The module is designed as an assembly of standardized linear sections with uniform geometric parallel arrangements. This segmentation enables pre-fabrication and pre-testing of individual sections on land, reducing manufacturing costs and simplifying quality assurance while maintaining system reliability through consistent modular construction.
3Productivity
If conventional flow line configurations are used, then fluid conveyance is achieved, but the system requires extensive field testing and welding
Solution Approach 1:
The linear sections are designed to be pre-assembled and pre-tested on land before subsea deployment. This preliminary action allows quality verification and system testing to be completed in controlled terrestrial environments, eliminating the need for extensive field testing and welding operations in challenging subsea conditions.
