Articulating Boom Stabbing Basket for Pipe Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stabbing boards and baskets in oil and gas well drilling lack sufficient horizontal movement, compact stowability, and mobility around tubulars, limiting operator access and efficiency during pipe-stabbing operations.
Innovation Solution
A stabbing basket with a frame member, a platform, a carriage for vertical movement, and an articulating boom with pivoting actuators allowing horizontal and vertical movement, enabling the platform to be positioned flexibly around tubulars and stowed compactly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional stabbing board or basket is used, then the structure is simple and easy to manufacture, but the horizontal movement is insufficient and the operator cannot reach the other side of tubulars
Solution Approach 1:
The platform is divided into multiple segments: a base platform, an articulating boom with multiple segments, and a carriage system. This segmentation allows each part to move independently, providing extensive horizontal movement capability while keeping individual components relatively simple in design.
Solution Approach 2:
The platform transitions from a static structure to a dynamic system with multiple moving parts including the articulating boom, carriage, and telescoping sections. This enables the platform to adapt its position and configuration to reach different locations around tubulars during stabbing operations.
2Ease of operation
If the platform provides extensive horizontal movement, then operator access is improved, but the device becomes more complex and harder to stow
Solution Approach 1:
The articulating boom segments are designed to nest within each other when not in use, with the second segment storing within the first segment. This nesting mechanism allows the extended platform to be compacted into a small footprint, reducing interference with rig operations when the stabbing basket is not needed.
Solution Approach 2:
The platform uses dynamic folding and telescoping mechanisms that allow it to transition between an extended operational configuration and a compact stowed configuration. The articulating boom can be folded at multiple joints and the telescoping sections can be retracted, enabling easy stowage while maintaining full mobility when deployed.
3Adaptability or versatility
If the platform is fixed in position, then the structure is stable and simple, but the operator cannot move around the pipe or tubulars during stabbing operations
Solution Approach 1:
The platform is segmented into multiple movable sections including the base platform, articulating boom segments, and carriage components. This segmentation allows each segment to move independently relative to the others, providing versatile position adjustment capability while keeping individual movement mechanisms relatively simple.
Solution Approach 2:
The platform is designed as a multi-functional system that can perform multiple operations: vertical movement via the carriage, horizontal movement via the articulating boom, and positioning around tubulars. This universal design allows a single platform to handle various stabbing operation scenarios without requiring multiple specialized devices.

AI summary
A stabbing basket, for a rig and for supporting a worker while stabbing joints of tubular members together during running operations, comprises a frame member for mounting the stabbing basket to the rig, a platform to support the worker, a carriage to slidably mount the platform to the frame member, vertical power means for moving the carriage vertically with respect to the frame member, an articulating boom, interconnecting the platform with the carriage, said articulating boom comprising a first segment and a second segment, and at least one pivoting actuator positioned between the first segment and the second segment.
