Seismic Node Carrier With Pusher-Guided Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in efficiently transporting and deploying a large number of seismic nodes between a vessel on a sea surface and a depth near or at a sea floor, and in providing a reliable method for transferring nodes to and from the sea floor, particularly without a direct connection between nodes.
Innovation Solution
A carrier system with an interior for storing seismic nodes, equipped with pushers and guides, allows for the movement of nodes between the carrier and a node transfer position, enabling efficient transport and deployment using a manipulator arm or similar tool, and includes a method for loading and unloading nodes manually or with a tool.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a carrier system is designed to transport a large number of seismic nodes, then the transport capacity increases, but the device complexity increases
Solution Approach 1:
The carrier system is divided into multiple compartments or sections, each capable of holding and transporting seismic nodes independently. This segmentation allows the system to handle large quantities of nodes while maintaining manageable complexity in each section, as each compartment can be operated and maintained separately.
Solution Approach 2:
The carrier system is designed with universal components that can handle different types of seismic nodes through standardized interfaces and manipulation mechanisms. The manipulator arm and transfer mechanisms are configured to work with various node designs, reducing the need for specialized equipment for each node type and thereby controlling overall system complexity.
2Ease of operation
If manual or tool-based loading methods are used, then the ease of operation improves, but the productivity decreases
Solution Approach 1:
The carrier system incorporates self-loading capabilities where the manipulator arm and internal mechanisms can automatically position and load seismic nodes into the carrier without requiring extensive manual intervention. The system serves itself by having integrated manipulation and transfer mechanisms that reduce dependency on external tools and operators, thereby maintaining ease of operation while significantly improving loading productivity.
