Swivel Device for Bowl Outlet Alignment in Oil and Gas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the oil and gas industry, the fixed positioning of the bowl during installation often results in misalignment of the outlet with the flowline, necessitating bowl removal and modification, leading to increased downtime, operational costs, and non-productive time.
Innovation Solution
A swivel device that attaches to the bowl, allowing the outlet to be adjusted and aligned with the flowline by rotating a flange-secured neck within a shoulder, reducing the need for bowl removal and simplifying the connection process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the bowl is installed in a fixed position, then the installation structure is simple, but the outlet may not align with the flowline requiring bowl removal and modification
Solution Approach 1:
The bowl is designed with rotational capability around its vertical axis, transforming from a static fixed installation to a dynamic adjustable installation. The bowl can rotate to different angular positions to align the outlet with the flowline while maintaining the simple fixed-position installation structure through the stack connection.
2Manufacturing precision
If the bowl is removed and modified to align the outlet with the flowline, then the alignment is achieved, but the operation time increases and operating costs increase
Solution Approach 1:
The bowl is pre-designed with rotational capability and outlet positioning features that enable alignment adjustments to be made during installation without requiring removal or modification. The preliminary design incorporates the alignment function into the bowl structure itself, allowing rig personnel to simply rotate the bowl to the correct orientation rather than performing time-consuming removal and modification operations.
3Manufacturing precision
If the bowl is removed and modified, then the outlet alignment is achieved, but the operating costs increase
Solution Approach 1:
The rotational capability of the bowl eliminates the need for costly removal and modification operations. By designing the bowl to rotate and align during installation, the system avoids generating harmful economic effects such as increased operating costs, rig non-productive time, and additional labor requirements associated with bowl removal and modification.

AI summary
The swivel device attaches to a bowl or is implemented as a component of the bowl. The swivel device enables adjustment of the bowl to align the outlet with the flowline. A flange of the swivel device includes multiple fastener apertures for securing the flange to the stack. The swivel device secures the bowl to the stack while allowing rotation of the bowl. Rotation of the bowl adjusts the positioning of the outlet to align the outlet with the flowline for connecting the outlet to the flowline.
