Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual riser section connecting process is used, then operator control and flexibility are maintained, but operator safety deteriorates due to exposure to repetitive motion injuries and human error
Solution Approach 1:
The patent introduces an automated riser section connecting system that acts as an intermediary between the operator and the heavy components. The system includes automated alignment mechanisms, robotic handling tools, and computer-controlled locking systems that perform the physically demanding tasks while operators monitor and control the process remotely through a control station, thereby improving safety without completely eliminating operator control
Solution Approach 2:
The patent replaces manual mechanical operations with automated mechanical and electronic systems. This includes automated alignment systems using sensors and actuators, robotic manipulators for handling heavy riser sections, and computer-controlled locking mechanisms that substitute for manual labor, reducing operator exposure to physical hazards while maintaining precise control
2Productivity
If manual riser section connecting process is used, then procedural flexibility is maintained, but productivity deteriorates due to time-intensive procedures
Solution Approach 1:
The patent implements preliminary alignment and positioning systems that prepare riser sections for connection before the actual joining operation. Sensors detect misalignments and automated actuators correct them in advance, and components are pre-positioned using robotic systems, thereby reducing the time required for the critical connection phase without requiring overly complex real-time adjustment mechanisms
Solution Approach 2:
The patent incorporates feedback systems with sensors that monitor the connection process in real-time, providing data to the control system about alignment status, component positioning, and locking force application. This feedback enables automated adjustments and optimization of the connection process, improving productivity while managing system complexity through intelligent control algorithms
3Manufacturing precision
If manual riser section connecting process is used, then adaptability to varying conditions is maintained, but manufacturing precision deteriorates due to human error
Solution Approach 1:
The patent replaces manual alignment and positioning operations with automated systems using sensors, lasers, and computer-controlled actuators that provide consistent, repeatable precision. The automated systems eliminate human error in measurement and adjustment while maintaining the ability to adapt to varying conditions through programmable control algorithms that can be adjusted for different riser configurations and environmental conditions
Data Source
AI summary
Systems and methods for riser monitoring and lifecycle management are disclosed. The riser monitoring and lifecycle management method includes receiving a signal indicative of an identification of a riser component at a monitoring and lifecycle management system (MLMS), wherein the riser component forms part of a riser assembly. The method also includes detecting one or more properties via at least one sensor disposed on the riser component during operation of the riser assembly, and communicating data indicative of the detected properties to the MLMS. The MLMS stores the data indicative of the detected properties with the identification of the riser component in a database.
