Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If remote operation of fluid connections is implemented, then operator safety is improved, but system complexity increases
Solution Approach 1:
A remote operator interface and control unit is introduced as an intermediary device that enables operators to monitor and control fluid connections from a safe distance. The control unit communicates with fluid connection housing assemblies through hydraulic lines and electrical signals, allowing remote actuation of locking rings and monitoring of connection status without requiring operators to be physically present at the wellhead
Solution Approach 2:
Manual mechanical operation of fluid connections is replaced with a hybrid system combining hydraulic actuation and electrical control. Hydraulic pistons are used to actuate locking rings and cam locks, while electrical sensors and communication circuits enable remote monitoring and control, eliminating the need for direct mechanical manipulation by operators
2Productivity
If multiple fluid connections are monitored and controlled concurrently, then productivity is improved, but device complexity increases
Solution Approach 1:
The remote operator interface and control unit is designed as a universal system capable of monitoring and controlling multiple fluid connection housing assemblies simultaneously. The control unit can independently manage each connection while providing concurrent operation, allowing a single operator to efficiently manage multiple wellheads from one location
Solution Approach 2:
The control system is segmented into independent control modules, each capable of managing individual fluid connections. This modular approach allows the system to handle multiple connections concurrently while maintaining independent control over each, reducing the complexity burden of managing multiple functions in a monolithic system
3Measurement precision
If real-time status monitoring is implemented, then measurement precision is improved, but device complexity increases
Solution Approach 1:
Electrical sensors are integrated into the fluid connection housing assemblies to provide real-time feedback on connection status, locking ring position, and pressure conditions. This feedback is transmitted to the remote operator interface, enabling precise monitoring of the actual state of each connection and allowing operators to make informed decisions
