Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pipeline maintenance techniques, such as double block and bleed apparatus, lack effective monitoring systems to provide real-time data on operating conditions, making it difficult to manage and schedule maintenance efficiently.
Innovation Solution
A pipe isolation and monitoring system that includes a pipe isolation device with primary and secondary sealing heads, sensors to measure data from different zones, and a data acquisition device capable of transmitting and processing data locally or remotely, triggering alarms and actions based on set thresholds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a double block and bleed apparatus is used to isolate a pipeline, then the pipeline can be sealed and maintenance can be performed, but there is no monitoring system to provide real-time data on operating conditions
Solution Approach 1:
The patent implements a monitoring system with sensors that continuously measure operating conditions (temperature, pressure, vibration, etc.) in the live pipe zone, isolated zone, and zero-energy zone. This data is transmitted to a data acquisition device that provides real-time feedback on the isolation device's performance, enabling operators to monitor seal integrity, detect anomalies, and schedule maintenance proactively rather than reactively.
2Loss of information
If comprehensive sensors and data acquisition systems are added to monitor pipeline conditions, then real-time operating data becomes available, but the device complexity increases
Solution Approach 1:
The monitoring system is segmented into three distinct functional zones: (1) live pipe zone sensors that monitor conditions upstream of the isolation device, (2) isolated zone sensors that monitor the sealed section, and (3) zero-energy zone sensors that monitor downstream conditions. Each zone has dedicated sensors and data acquisition capabilities, allowing the complex monitoring function to be divided into manageable, independent modules that can be installed and maintained separately.
3Reliability
If multiple sensors and data acquisition devices are installed to monitor all zones, then comprehensive monitoring is achieved, but the cost and installation complexity increase
Solution Approach 1:
The monitoring system employs universal, multi-functional sensors and data acquisition devices that can monitor multiple parameters (temperature, pressure, vibration) across different zones. The data acquisition device is designed to receive and process data from various sensor types, reducing the need for specialized equipment for each measurement function and simplifying installation and maintenance procedures.
