Remote Clamp Head Installation for Axially Retained Control Lines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing axially-retained control line clamps require a human operator to be present at well center to secure them onto the tubular string, which can be hazardous and time-consuming.
Innovation Solution
A remote control line clamp installation system that includes a clamp head and a manipulator assembly to automatically position and secure axially-retained control line clamps onto the tubular string, allowing for installation without a human operator at well center.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If axially-retained control line clamps are used, then installation is simplified by not requiring two halves that encircle the tubular, but a human operator must be present at well center to drive the sections into position
Solution Approach 1:
The clamp installation system enables self-service operation through the automated manipulation system that positions and secures the clamp sections without requiring a human operator at well center. The system uses a manipulator arm with positioning mechanisms to automatically perform the installation tasks
Solution Approach 2:
The manual mechanical operation of driving clamp sections into position is replaced by an automated manipulation system. The system substitutes human mechanical action with automated positioning mechanisms including manipulator arms, actuators, and control systems that perform the same function remotely
2Reliability
If a human operator drives the clamp sections into position, then the clamp is secured to the coupling, but the process is time-consuming and exposes the operator to hazards
Solution Approach 1:
The system performs the clamp securing operation autonomously without human intervention at well center. The automated manipulation system executes the entire sequence of positioning and securing operations, eliminating the time loss associated with human operator deployment and exposure hazards
3Object-affected harmful factors
If remote automated installation is implemented, then worker safety is improved and installation time is reduced, but the device complexity increases
Solution Approach 1:
The manipulation system is designed with multi-functionality to perform multiple operations including positioning, gripping, and securing of clamp sections. This universal approach consolidates multiple functions into a single integrated system, managing complexity through functional integration rather than separate dedicated mechanisms for each task

AI summary
A clamp installation system includes a clamp head configured to engage a top section and a bottom section of an axially-retained control line clamp. The clamp installation system also includes a manipulator assembly configured to bring the clamp head close to and away from a tubular string run into a well. The clamp head is configured to position the top and bottom sections of the axially-retained control line clamp on opposite axial sides of a coupling of the tubular string. The clamp head is configured to drive the top and bottom sections of the axially-retained control line clamp axially-together so as to secure the axially-retained control line clamp to the coupling.
