Removable Fastening Mechanism for Marine Seismic Nodes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing marine seismic systems require complex equipment for attaching and detaching autonomous seismic nodes from deployment lines, necessitating specific node locks and attachment mechanisms that complicate the process.
Innovation Solution
A removable fastener system, such as staples or bands, is used to securely attach and detach the deployment line from the seismic nodes, allowing for easy and efficient deployment and retrieval without the need for complicated equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex attachment mechanisms with specific node locks are used, then the deployment line is securely fastened to the nodes, but the device complexity and operational complexity increase
Solution Approach 1:
The attachment system is divided into separate components: a deployment line with integrated fastening elements and nodes with corresponding receptacles. This segmentation allows each component to be optimized independently while simplifying the overall attachment mechanism, eliminating the need for complex dedicated node locks.
Solution Approach 2:
The deployment line is designed with multi-functional capabilities, serving both as the deployment medium and as the fastening mechanism through integrated staples, bands, or clamps. This universal design eliminates the need for separate attachment devices, reducing device complexity while maintaining secure fastening.
2Reliability
If complex attachment mechanisms with specific node locks are used, then the deployment line is securely fastened to the nodes, but the ease of operation decreases
Solution Approach 1:
The attachment mechanism is designed to be self-servicing during deployment and retrieval operations. The integrated fastening elements on the deployment line automatically engage with the node receptacles during deployment, and can be easily released during retrieval without requiring complex operational procedures or specialized equipment.
3Ease of operation
If simplified removable fasteners are used, then the ease of operation and deployment speed increase, but the reliability of secure fastening may be compromised
Solution Approach 1:
The fastening elements such as staples and bands are designed with curved or flexible geometries that allow them to conform to the node structure and deployment line configuration. This curvature enables simple insertion and removal while maintaining strong mechanical engagement during operation, balancing ease of operation with secure fastening reliability.

AI summary
Embodiments, including apparatuses, systems, and methods, for attaching autonomous seismic nodes directly to a deployment cable. The nodes may be attached to the deployment cable by a removable fastener or insert. The fastener may be a staple that surrounds the cable and rigidly couples to the node to securely fasten the cable to the node. The fastener may be secured into the node itself, a housing or enclosure surrounding the node, or into a receiver or mechanism attached to the node. Other fasteners besides a staple may include bands, wires, pins, straps, ties, clamps, and other similar devices that may be inserted around a portion of the deployment line and be removably coupled to the node. After retrieval of the node, the fastener may be removed and discarded.
