Coil Protector Assembly for Flexible Pipe Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for loading and unloading coils of flexible pipe are inefficient, requiring extra equipment and manual labor due to the large and heavy nature of the coils, which poses a challenge in transportation and deployment.
Innovation Solution
A coil protector system comprising a radially curved outer surface with a coil contacting base and a side wall that blocks circumferential movement, along with a passage for securing a coil restraint, which is used to attach the coil to a transportation carrier, facilitating secure and efficient handling of coils during transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If coils of flexible pipe are transported as large and heavy coils, then the pipe can be durable and operational in harsh conditions, but extra equipment and manual labor are required for loading and unloading
Solution Approach 1:
A coil restraint system acts as an intermediary device between the heavy coil and the transportation carrier. The coil restraint includes a coil contacting base with a radially curved outer surface that contacts the coil, side walls that block circumferential movement, and a passage for securing the restraint to the carrier, thereby facilitating easy loading and unloading without direct manual handling of the heavy coil
Solution Approach 2:
The coil restraint system is divided into separate functional components: a coil contacting base for supporting the coil, side walls for preventing movement, and a passage for securing mechanisms. This segmentation allows each component to perform its specific function efficiently, making the overall system easier to operate despite the heavy weight of the coil
2Reliability
If coils of pipe are made large to accommodate high pressures and temperatures, then the pipe can handle harsh operating conditions, but the coils become heavy and difficult to transport
Solution Approach 1:
The coil restraint serves as a mediator that enables the transportation of heavy coils without requiring proportional increases in handling equipment weight. The restraint system distributes the load and provides mechanical advantage, allowing standard transportation equipment to handle large, heavy coils reliably
3Ease of operation
If extra equipment is used to handle heavy coils, then the coils can be loaded and unloaded, but the process becomes more complex and time-consuming
Solution Approach 1:
The coil restraint system is designed as a universal device that can be applied to different coil sizes and transportation carriers. The coil contacting base with its radially curved surface adapts to various coil dimensions, and the restraint can be secured to different types of carriers using the passage, reducing the need for specialized equipment for each handling scenario

AI summary
A system includes a coil contacting base. The coil contacting base includes a radially curved outer surface with a radius of curvature less than or equal to a coil radius of curvature of an interior channel of a coil of spoolable pipe, and the coil contacting base includes a length greater than or equal to an axial dimension of the coil. The system also includes a side wall coupled to an inner surface of the coil contacting base. The side wall is configured to block circumferential movement of a coil restraint. The system also includes a passage disposed between the coil contacting base and the side wall. The coil restraint is configured to be disposed in the passage.
