Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional coil structure units are time-consuming and crane-dependent, requiring simultaneous well control equipment assembly and numerous crane operations, leading to delays and increased costs.
Innovation Solution
A coil tubing tower structure with 50-foot intermediate units, integrated well control equipment, and a telescoping hoisting system that allows craneless assembly and operation, enabling faster and more efficient tool deployment and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional coil structure units are assembled using cranes with 9-foot sections, then the structure can be built section by section, but the assembly process becomes extremely time-consuming and crane-dependent
Solution Approach 1:
The tower structure is divided into modular intermediate units, each comprising a platform and crossbracing assembly. These standardized modules can be pre-assembled and then quickly connected to the base and to each other, reducing on-site assembly time while maintaining structural integrity
Solution Approach 2:
Components such as platform brackets, crossbracing, and well control equipment are pre-positioned and integrated into the intermediate units before delivery to the well site. This preliminary assembly eliminates the need for time-consuming crane operations during final installation
2Adaptability or versatility
If well control equipment is installed on each intermediate unit, then operational capability is improved, but the complexity of assembly increases
Solution Approach 1:
Well control equipment is integrated directly onto the intermediate units during manufacturing, combining the platform structure with functional equipment. This merging reduces the number of separate installation steps and crane operations needed, as entire equipped modules are installed as single units
Solution Approach 2:
The intermediate units are designed as universal modules that can accommodate various well control equipment configurations. Each unit serves multiple functions: structural support, equipment mounting, and operational control, reducing the need for specialized components
3Productivity
If the tower structure uses longer intermediate units of 50 feet, then the number of sections and connections is reduced, but the handling and installation difficulty increases
Solution Approach 1:
The intermediate units are designed with flexible connection points and adjustable mounting mechanisms that adapt to varying installation conditions. This dynamic design allows long 50-foot units to be easily positioned and secured without requiring precise pre-alignment, maintaining ease of operation despite increased length

AI summary
A coil structure unit comprises a base and a tower structure, the tower structure comprises a plurality of intermediate units. The length of each of the plurality of intermediate sections can be about 50 feet. The length allows to utilize a manipulator that allows equipment such as lubricators and blowout preventers to be integral to the loads which will eliminate much of the rig up time and complication as well as having much more flexibility in operations to take the items on and off hole.
