Collapsible Spill Container for Drilling Rig Floor Drainage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drilling fluid spills onto the workover/drilling rig floor during pipe removal pose safety and environmental hazards, necessitating an effective drainage system for collection and recycling or proper disposal.
Innovation Solution
A collapsible concave spill container with a circular bottom opening and hangers/hooks for mounting to the rig floor, designed to catch and collect drilling fluid, with optional drainage systems directing fluid into a storage tank, utilizing flexible, leakproof materials like plastic or rubberized tarps for efficient fluid containment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a drainage system is implemented to collect drilling fluid, then safety and environmental hazards are reduced, but device complexity increases
Solution Approach 1:
The drainage system is divided into separate functional components: a collapsible concave container for fluid collection, circular rings for mounting, and drainage channels for fluid removal. This segmentation allows each component to be optimized independently and simplifies installation and maintenance while effectively addressing the safety hazard of drilling fluid spills.
2Ease of operation
If a collapsible concave container is used, then ease of operation is improved, but manufacturing precision requirements increase
Solution Approach 1:
The concave container is constructed from flexible materials that can be collapsed into a compact form for easy storage and deployment, then expanded to provide adequate fluid collection capacity. The flexibility allows the container to conform to the rig floor surface while maintaining sufficient structural integrity to contain drilling fluid, balancing ease of operation with acceptable manufacturing precision.
3Adaptability or versatility
If the container bottom opening is made circular to match tubular members, then adaptability is improved, but device complexity increases
Solution Approach 1:
The circular bottom opening design serves multiple functions: it provides a standardized interface for various tubular members (drill pipes, casing, wellheads), enables consistent positioning of the container, and simplifies the mounting structure by using circular rings that can accommodate different tubular dimensions. This universal design approach improves adaptability without proportionally increasing device complexity.

AI summary
A spill container to be mounted below a rig floor. The spill container includes a collapsible concave container having an open top for catching fluid spilled on the rig floor, and a circular bottom opening adapted to receive a tubular member extending through the rig floor and downward below the concave container. The side walls of the concave container extend from the open top to the circular bottom opening. The open top of the concave container has a plurality of hangers extending there about to mount to the rig floor. An outer circumference of the open circular bottom opening has a plurality of hooks attached thereto for mounting to circular rings through which the tubular member extends outwardly therefrom.
