Pivotable External Connector for Seismic Streamer Connection Module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing connection modules for streamer spreads in marine seismic data acquisition systems require stopping the winding/unwinding process to disconnect and reconnect, which is time-consuming and hinders the efficiency of the survey.
Innovation Solution
A flush module with a housing, end connectors, and a pivotable or rotatable external connector that allows connection and disconnection without interrupting the winding/unwinding process, minimizing weight and hydrodynamic noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an external connection module is used to connect float and rope to streamer sections, then connection functionality is provided, but the winding/unwinding process must be stopped and the module disconnected/reconnected
Solution Approach 1:
The external connector is nested within the housing of the flush module, allowing it to be stored inside the module body during winding/unwinding operations. The connector can be deployed outward when connection is needed, eliminating the need to stop the winding process for module replacement.
Solution Approach 2:
The external connector is made movable relative to the housing, transitioning between a retracted position (during winding/unwinding) and an extended position (during connection operations). This dynamic configuration allows the module to adapt to different operational states without interruption.
2Adaptability or versatility
If traditional external connection modules are used, then connection capability is achieved, but operational time is increased due to stopping and restarting the winding process
Solution Approach 1:
The flush module design allows the winding/unwinding process to continue uninterrupted while the external connector is retracted inside the housing. Connection operations can be performed without stopping the main workflow, maintaining continuous productive action.
Solution Approach 2:
The external connector is pre-positioned inside the housing in a ready state, allowing it to be quickly deployed when needed without requiring module replacement or complex setup procedures during operational pauses.
3Adaptability or versatility
If external connection modules are used, then connection function is provided, but noise is increased during streamer operations
Solution Approach 1:
By nesting the external connector inside the housing during streamer operations, the overall profile of the flush module is minimized. This reduces hydrodynamic drag and associated noise compared to traditional modules with permanently exposed external connectors.
Solution Approach 2:
The connector is only exposed externally when connection is actually needed, rather than being permanently external. This localized exposure minimizes the time during which the module generates additional hydrodynamic noise, while still providing full connection functionality when required.

AI summary
Method and flush module for connecting streamer sections to an external device. The flush module includes a housing; a first end connector attached to the housing and configured to connect to a first element of the streamer spread; a second end connector attached to the housing and configured to connect to a second element of the streamer spread; and an external connector attached to the housing and configured to connect to a third element of the streamer spread. The external connector is configured to pivot between (a) a close position during which the external connector is entirely located within the housing, and (b) an open position during which a distal end of the external connector is located outside the housing.
