Control and Supply Unit for Oilfield Actuating Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing control and supply units for actuating devices in oil and natural gas production, such as chokes and blow-out preventers, face challenges in maintaining a stable and accessible power and data connection, especially in submarine environments, where direct cable connections can be cumbersome and prone to damage.
Innovation Solution
A control and supply unit design that separates the plug connection module from the main unit, allowing for easier external access and placement, using a cable connection to connect the plug connection module to the actuating device, and incorporating a redundant setup with a remotely operated vehicle (ROV) for backup power and control, ensuring compliance with standards like SIIS.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the plug connection module is integrated directly into the control and supply unit, then the structural design is compact, but the accessibility and ease of maintenance are reduced
Solution Approach 1:
The plug connection module is separated from the control and supply unit into a distinct, standalone component. This segmentation allows the connection module to be accessed independently for maintenance and replacement without affecting the main control unit, thereby improving accessibility while maintaining a relatively compact overall structure through modular design.
2Stability of the object's composition
If the plug connection module is arranged on the actuating device, then the stability of the arrangement is improved, but the ease of external access is reduced
Solution Approach 1:
The plug connection module is designed with movable or adjustable mounting mechanisms that allow it to be positioned optimally for external access while maintaining a stable connection to the actuating device. The module can be dynamically adjusted during installation and operation to achieve the best balance between stability and accessibility.
3Ease of operation
If a cable connection is used to connect the plug connection module to the actuating device, then the ease of connection is improved, but the reliability of the connection is reduced
Solution Approach 1:
A cable connection serves as an intermediary element between the plug connection module and the actuating device, providing a flexible and easy-to-establish connection while incorporating protective measures such as strain relief, shielding, and secure mounting fixtures to maintain connection reliability under various operating conditions.

AI summary
A control and supply unit for an actuating device of a choke, a valve, a blow-out preventer or some other device applied in the field of oil and natural gas production. The control and supply unit includes an auxiliary power supply that is rechargeable and a connecting means to exchange data or supply a voltage. The unit is implemented separately from the actuating device and the connecting means is connected via a cable connection to a separate plug connection module arranged on the actuating device.
