Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If flowline jumpers are subjected to large static and dynamic loads during installation and production, then fluid communication between subsea structures is maintained, but the conduit and connectors may be damaged or fatigued, compromising connection integrity

Engineering Contradiction:
Improveconnection integrityVSAvoidvibrational damage
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies preliminary action by installing sensors on the flowline jumper before it is subjected to operational loads. These sensors are positioned to detect vibrations and loads during installation and production, enabling early warning of potentially damaging conditions before actual damage occurs to the conduit or connectors.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback by continuously monitoring vibration and load data from sensors on the flowline jumper and transmitting this information to surface locations. This feedback loop allows operators to assess the state of the flowline jumper in real-time and take corrective actions when threshold values are exceeded, preventing vibrational damage while maintaining reliable fluid communication.

Inventive Principle:
Principle #23Feedback

2Reliability

If real-time monitoring of vibration and load is implemented on the flowline jumper, then damaging vibrational conditions can be detected and prevented, but device complexity increases due to sensor deployment and data transmission systems

Engineering Contradiction:
Improveflowline jumper integrityVSAvoidsensor and monitoring system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies universality by designing a monitoring system that uses multi-functional sensors capable of detecting both vibration and load parameters simultaneously. The same sensor infrastructure serves multiple purposes: monitoring installation conditions, tracking production operations, and providing data for both immediate operational decisions and long-term integrity assessment, thereby reducing overall system complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent implements self-service by enabling the flowline jumper monitoring system to automatically assess its own state through embedded sensors that continuously measure vibration and load. The system self-diagnoses potential issues by comparing measured parameters against threshold values, eliminating the need for external inspection equipment or manual assessment procedures.

Inventive Principle:
Principle #25Self-service
