Solution Overview
Problem
Existing technologies do not effectively direct fluid flow or transport tools within underwater structures, lacking the ability to dynamically control fluid flow patterns and tool transportation in subsea environments.
Innovation Solution
An arrangement comprising multiple flow line configurations with movable distribution devices that allow for interconnection of flow lines, enabling selection of various fluid flow patterns and tool transportation by either fluid pressure or dedicated means, including a housing with ports and a selector body that can be positioned to direct fluid flow between lines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing fluid distribution apparatuses are used, then fluid distribution is achieved, but dynamic control of fluid flow patterns and tool transportation in subsea environments is not possible
Solution Approach 1:
The distribution device incorporates a movable selector body that can be positioned in different locations to dynamically change fluid flow paths. This allows the system to adapt between different flow patterns (e.g., single-line flow, multi-line flow, looped flow) without requiring multiple separate devices, thereby achieving dynamic control while managing complexity through a single adjustable mechanism.
Solution Approach 2:
The distribution device serves multiple functions: it distributes fluid to multiple flow lines, enables tool transportation, creates looped circulation patterns, and provides selective connectivity between different flow lines. By consolidating these functions into a single device with a movable selector body, the patent achieves versatility without proportionally increasing system complexity.
2Adaptability or versatility
If multiple flow line configurations are implemented, then flexible fluid flow patterns and tool transportation are enabled, but device complexity increases
Solution Approach 1:
The distribution device is segmented into distinct functional components: a housing with multiple ports for different flow lines, a movable selector body with positioning mechanisms, and connection elements to the flow lines. This segmentation allows each component to perform its specific function while the overall structure remains modular and manageable, enabling multiple flow configurations without overwhelming complexity.
Solution Approach 2:
The selector body is designed to be movable between different positions, each corresponding to a specific flow pattern configuration. This dynamic element allows the system to switch between single-line flow, multi-line flow, and looped circulation by simply repositioning the selector body, thereby achieving versatility through a single adjustable mechanism rather than multiple fixed devices.
