Disconnectable Mooring Connector With Guide Channel Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional disconnectable anchoring systems for offshore vessels require complex and costly operations, such as using remotely operated vehicles (ROVs), due to the need for precise positioning and maintenance to prevent disengagement of mooring lines, which are prone to removal unless sufficient tension is maintained.
Innovation Solution
A mooring system with a connector structure and anchor structure that includes an open guide channel allowing for easy connection and disconnection of mooring lines without the need for ROVs, featuring a terminal region that retains the engagement portion, preventing upward or lateral movement, and a longitudinal opening for mooring line access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional disconnectable anchoring systems are used, then the mooring line can be connected and disconnected, but the system requires complex operations using remotely operated vehicles (ROVs) and accurate positioning
Solution Approach 1:
The anchoring system is divided into separate components: a connector structure with engagement portion and a guide channel structure with retaining portion. This segmentation allows the mooring line to be connected and disconnected by simply moving the connector along the guide channel, eliminating the need for complex ROV operations while maintaining disconnectability
Solution Approach 2:
The guide channel structure acts as an intermediary between the connector and the mooring line. The guide channel with its retaining portion provides a simple mechanical constraint that guides and secures the connector, replacing the need for complex ROV-controlled positioning and retention mechanisms
2Reliability
If conventional anchoring systems are used, then the mooring line can be retained, but the system requires sufficient tension to prevent removal from the tube
Solution Approach 1:
The guide channel structure provides dynamic retention through its geometric design. The retaining portion naturally holds the engagement portion through mechanical constraint rather than relying on constant tension, allowing the system to maintain reliability whether the mooring line is under tension or slack
Solution Approach 2:
The guide channel structure is self-retaining through its geometric configuration. The retaining portion automatically secures the engagement portion without requiring external tension or active control, enabling maintenance operations to be performed by simply moving the connector along the channel without complex positioning requirements
3Manufacturing precision
If accurate positioning is required for cable and socket, then the connection can be secured, but the installation becomes complex and time-consuming
Solution Approach 1:
The system separates the positioning function (guide channel) from the connection function (connector). The guide channel structure provides inherent guidance through its geometry, allowing the connector to be engaged without precise positioning requirements, thereby reducing installation time and complexity
Solution Approach 2:
The guide channel acts as an intermediary that absorbs positioning tolerances. Its geometric design with retaining portion provides mechanical guidance and constraint, eliminating the need for precise cable and socket alignment while maintaining secure connection

AI summary
Disclosed is a mooring system (1) for mooring a floating vessel. The mooring system includes a connector structure (10) for attachment to a mooring line and an anchor structure (20) to be anchored to a sea bed. The connector structure comprises an engagement portion (14) and an attachment portion (12). The anchor structure comprises an open guide channel (22) extending from an entrance region (24) to a terminal region (26); and sized to accommodate at least the engagement portion of the connector structure. A longitudinal opening to the guide channel provides access for a mooring line connected to the attachment portion, while the connector and anchor structures are connected and disconnected. Connection and disconnection can be controlled from the water surface.
