Solution Overview

Problem

Automated coupling systems for marine loading arms often fail due to incompatibility or deterioration of coupling devices and target ducts, leading to unreliable fluid connections and potential leaks.

Innovation Solution

A marine loading system that uses an imaging system to capture images, construct 3D representations of target ducts, determine compatibility, and move the coupling device accordingly, ensuring reliable connection by assessing the compatibility of the coupling device with the target duct before attempting to connect.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If automated coupling systems are used to connect coupling devices with target ducts, then productivity and ease of operation are improved, but reliability deteriorates due to incompatibility or deterioration of coupling components leading to connection failures and leaks

Engineering Contradiction:
Improveloading speedVSAvoidconnection reliability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system performs preliminary actions by capturing images of the target duct before coupling, constructing 3D representations, and determining compatibility characteristics in advance. This allows the system to identify incompatible or deteriorated target ducts before the coupling attempt, preventing connection failures and leaks while maintaining automated operation efficiency

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The imaging system and image processing algorithms serve as intermediaries between the automated coupling system and the physical coupling operation. These intermediaries provide critical information about target duct compatibility, enabling the control system to make informed decisions about whether to proceed with coupling, thus improving reliability without reducing automation

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If compatibility assessment is added to the automated coupling system, then reliability is improved, but device complexity increases

Engineering Contradiction:
Improveconnection reliabilityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The imaging system serves multiple functions: it captures images for documentation, constructs 3D representations for geometric analysis, determines compatibility characteristics, and provides feedback to the control system. By making the imaging system multi-functional, the patent avoids adding separate dedicated sensors or measurement devices, thereby improving reliability without proportionally increasing system complexity

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

Solution Approach 2:

The system performs self-assessment of target duct compatibility using its own imaging and processing capabilities. The control system automatically analyzes the 3D representations and compatibility characteristics without requiring external inspection equipment or manual verification, enabling reliability improvement through self-service rather than additional complex external systems

Inventive Principle:
Principle #25Self-service
