Base Beam Stabilizer Arms for Derrick Rig Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing self-propelled derrick rigs face challenges in stability and mobility due to the limitations of guy wire systems, particularly in multi-well pad environments where permanent anchors are not feasible, leading to increased setup time and reduced operational efficiency.
Innovation Solution
A portable base beam system with stabilizer arms and a counterweight assembly that allows for quick and stable mounting of self-propelled derrick rigs, featuring a longitudinally extending metal main beam with pivotally attached stabilizer arms and adjustable stabilizer pads, along with a counterweight sled to prevent the rig from tipping or lifting off the ground.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If guy wires are used to stabilize the rig, then the rated capacity of the rig is significantly increased, but the setup time is longer and the rig cannot be deployed in multi-well pad environments without permanent anchors
Solution Approach 1:
The base beam is divided into multiple sections that can be assembled together to form a stable support structure. This segmentation allows the base beam to be transported in manageable pieces and quickly assembled at the work site without requiring permanent anchors or extensive setup time, while still providing the necessary stability and load capacity.
Solution Approach 2:
The base beam acts as an intermediary structure between the self-propelled rig and the ground. It provides a stable foundation that distributes the rig's weight and operational loads over a larger area, eliminating the need for guy wires and permanent anchors while reducing setup time.
2Strength
If guy wires are used to stabilize the rig, then the rig can operate at higher load capacities, but the rig requires specific locations for guy attachment which reduces mobility and adaptability
Solution Approach 1:
The base beam is designed as a universal support structure that can be deployed in various locations and configurations. It provides multiple attachment points for the rig and can accommodate different operational requirements, making the system adaptable to multi-well pad environments and various ground conditions without requiring specific guy wire locations.
3Adaptability or versatility
If a portable base beam is used instead of permanent anchors, then the rig can be deployed in multi-well pad environments, but the base beam must be sufficiently heavy and stable to support the rig without permanent ground anchoring
Solution Approach 1:
The base beam is segmented into multiple sections that can be assembled together to achieve the necessary weight and stability. This allows the base beam to be heavy enough to support the rig without permanent anchors while still being transportable in manageable pieces on standard equipment.
4Strength
If the base beam has a larger footprint and more guy attachment points, then the stability and load capacity are improved, but the transportation and setup complexity increases
Solution Approach 1:
The base beam is divided into modular sections that can be easily assembled and disassembled. This segmentation provides multiple guy attachment points and a large footprint for stability while keeping each individual section manageable for transportation and setup, reducing overall complexity.

AI summary
Improvements to base beams and self-propelled derrick rigs are described. The base beam can have two or more stabilizer arms which can be deployed. The base beam is also designed to support the derrick rig. An optional counterweight assembly can be connected to the front of the rig. The self-propelled derrick rig can be easily and quickly mounted to the base beam, and when mounted, the assembly will be able to withstand high hook loads and wind loading without the danger of the rig coming off of its wheels or falling over.
