Double-Hose Water Line Junction for Leak Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for overland fluid transfer, particularly in the oil and gas industry, lack effective leak protection and containment, leading to environmental risks and inefficiencies in water usage, especially when using produced water.
Innovation Solution
A water transport system utilizing double-layered flexible lay-flat hoses with a junction device that includes two chambers separated by a dividing plate, allowing for secondary containment and leak detection through sensors and sight glasses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If single-layered hoses are used for fluid transfer, then the device complexity is reduced, but leak protection and containment capability are insufficient
Solution Approach 1:
The patent implements a dual-hose configuration where an inner hose is nested within an outer hose. The inner hose carries the fluid while the outer hose provides secondary containment. This nesting structure enables leak detection and environmental protection without requiring completely separate parallel hose systems, thus balancing reliability improvement with manageable device complexity.
Solution Approach 2:
The hose system is segmented into distinct functional layers: the inner hose for fluid transport and the outer hose for containment. This segmentation allows each layer to perform its specific function optimally while maintaining overall system reliability through the containment capability of the outer hose.
2Quantity of substance
If produced water is transported over land, then water availability is improved, but environmental contamination risk increases
Solution Approach 1:
The outer hose serves as a pre-established protective barrier that cushions against potential leaks from the inner hose before they can reach the environment. This prior cushioning measure allows produced water to be transported over land by containing any potential leaks within the outer hose, thus enabling water availability improvement while mitigating environmental contamination risk.
3Length of moving object
If multiple hoses are connected in series for long-distance transfer, then transport distance is extended, but leak detection and response time are reduced
Solution Approach 1:
The patent incorporates visual indicators that provide immediate feedback when a leak occurs in the inner hose. The indicators are positioned at accessible locations along the hose assembly, enabling rapid detection and response to leaks even in long-distance configurations. This feedback mechanism compensates for the increased response time that would normally accompany extended transport distances with multiple connected hoses.

AI summary
A system includes first and second hose segments and a first junction device. The first hose segment includes first inner and outer hoses. The second hose segment includes second inner and outer hoses. The first junction device includes a first body including first and second chambers and a selectively openable hatch disposed on at least one of the first and second chambers. The first outer hose is fluidly connected to first chamber. The second outer hose is fluidly connected to the second chamber. The first and second inner hoses are fluidly connected. Outside of the first and second inner hoses, interiors of the first and second chambers are fluidly isolated from each other. A method of transporting liquid over land comprises connecting a first hose segment to a liquid source and connecting first and second hose segments to a first junction device.
