Wellhead Safety Barrier Condulet for Smaller Hazardous-Area Cabinets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional safety devices for hydrocarbon recovery operations are cumbersome and costly due to the need for large safety enclosures to house sensitive equipment, leading to potential safety hazards and increased economic costs.
Innovation Solution
The use of a condulet that allows signal processing and dynamic pressure sensor equipment to be located outside the safety enclosure, reducing the need for extensive cabling and enabling more efficient data transfer, while maintaining safety through advanced sealing and signal processing capabilities within a hazardous environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If equipment is stored within the confines of the cabinet to prevent equipment from being in contact with a potentially dangerous environment, then safety is improved, but the cabinet size becomes larger
Solution Approach 1:
The system is divided into two separate locations: a safety enclosure (cabinet) and a field location. The condulet creates a segmented architecture where signal processing equipment can be located at the field location outside the safety enclosure, while maintaining safety barriers through proper isolation and sealing.
Solution Approach 2:
Signal processing and dynamic pressure sensor equipment are extracted from the safety enclosure and located outside it at the field location. This extraction reduces the cabinet size while maintaining safety through the condulet's isolation capabilities.
2Reliability
If spacing requirements are maintained between sensor electrical connections and other electrical connections to prevent arcing, then safety is improved, but the available space in cabinets becomes limited
Solution Approach 1:
Electrical equipment is extracted from the cabinet and located at the field location through the condulet. This eliminates the need for spacing requirements within the cabinet, maximizing available space while maintaining safety through proper isolation at the field location.
3Reliability
If extensive cabling is used to connect equipment inside the safety enclosure, then safety is maintained, but the complexity and cost of installation increases
Solution Approach 1:
Equipment is extracted from the safety enclosure to the field location, eliminating the need for extensive cabling between the cabinet and field equipment. The condulet provides a direct connection point at the field location, reducing cabling complexity while maintaining safety through proper isolation.
