Detachable Diving Board Assembly for Faster Drilling Rig Mobilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The inefficiencies in drilling rig assembly mobilization and downtime due to the need to install and dismantle equipment, including racking and diving boards, and the challenges of adapting to varying environmental conditions, are not adequately addressed by existing technologies.
Innovation Solution
A detachable racking board system that can be raised after the mast is already in place, allowing separate transport and coupling to different heights, and a detachable diving board that can be replaced or repaired without disassembling the mast, facilitated by a dolly and automated control system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the drilling rig assembly is mobilized by assembling all components including racking board and diving board before drilling begins, then the rig is ready for drilling operations, but the mobilization time takes up a considerable amount of time
Solution Approach 1:
The diving board is separated from the racking board into independent components. The racking board remains attached to the mast while the diving board can be independently installed, removed, or replaced by detaching it from the racking board using quick-connect mechanisms, eliminating the need to disassemble the entire rig structure.
Solution Approach 2:
The system transitions from a fixed, permanent installation to a dynamic, reconfigurable structure. The detachable diving board allows the rig configuration to be dynamically adjusted during operations based on environmental conditions, drilling requirements, or maintenance needs without prolonged downtime.
2Stability of the object's composition
If the diving board is permanently attached to the racking board, then the structure is stable, but the diving board cannot be easily replaced or repaired without disassembling the mast
Solution Approach 1:
The diving board is segmented as a separate module that attaches to the racking board through standardized connection interfaces. This segmentation allows the diving board to be independently accessed, removed, or replaced by simply detaching from the racking board without affecting the mast or racking board structure.
Solution Approach 2:
The system enables easy replacement of the diving board component. When the diving board needs repair or replacement, it can be quickly detached from the racking board, swapped with a new or repaired unit, and reattached using the quick-connect mechanisms, minimizing downtime while maintaining structural integrity.
3Ease of manufacture
If the racking board is transported attached to the mast, then the assembly is complete, but the weight burden on lifting systems increases
Solution Approach 1:
The racking board is separated from the mast into independent transportable components. The racking board can be transported separately and attached to the mast at the drilling site using the quick-connect mechanisms, reducing the weight that needs to be lifted and transported as a single assembly while maintaining complete functionality when assembled.
Solution Approach 2:
The racking board and diving board are prepared and positioned separately before final assembly at the drilling site. This preliminary separation allows for optimized transport logistics and reduces lifting requirements during mobilization, while the complete assembly is achieved through straightforward attachment operations at the destination.
4Ease of repair
If the entire rig assembly is disassembled for equipment repairs or changes, then all components can be accessed, but drilling operations are paused for extended periods
Solution Approach 1:
The diving board is segmented as an independently accessible component that can be removed from the racking board without disassembling the mast or other critical drilling structures. This segmentation enables maintenance personnel to access, repair, or replace the diving board while the drilling operations continue uninterrupted.
Solution Approach 2:
The system enables dynamic maintenance operations where the diving board can be quickly detached and replaced during drilling operations. The quick-connect mechanisms allow for rapid component swaps that minimize pause time, maintaining high productivity while ensuring component reliability and safety.
