Multi-level Wellhead Platform with Movable Upper Section
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wellhead work platforms in the oil and gas industry face challenges in providing unobstructed access for personnel to perform operations like ESP system installation while maintaining safety and structural integrity, especially when working at heights and around multiple wellheads.
Innovation Solution
A multi-level, portable wellhead work platform design featuring a lower platform mounted to a central riser with a blowout preventer, a movable upper platform, and structural elements like ladders, grating, and safety tie-off points, allowing 360-degree access and supporting heavy equipment and personnel weights, with collapsible and telescoping features for efficient repositioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed, permanent platform structure is used, then structural integrity and safety are improved, but adaptability and ease of repositioning deteriorate
Solution Approach 1:
The platform incorporates movable components including a movable second platform that can be repositioned relative to the first platform, telescoping supports that can extend and retract, and collapsible ladders. These dynamic elements allow the platform to adapt its configuration for different operational requirements while maintaining structural integrity through the rigid first platform and central riser structure.
2Ease of operation
If a multi-level platform with movable components is used, then adaptability and access flexibility are improved, but device complexity increases
Solution Approach 1:
The platform is divided into distinct functional segments: a fixed first platform mounted to the central riser, a movable second platform supported by the first platform, telescoping supports, and collapsible ladders. Each segment serves a specific function and can be independently positioned or collapsed, reducing overall complexity while maintaining operational flexibility.
3Ease of operation
If the second platform is made movable, then ease of operation and access to different positions are improved, but stability and reliability deteriorate
Solution Approach 1:
The first platform serves as a stable intermediary base that supports the movable second platform. The telescoping supports and hinges provide controlled movement mechanisms that maintain stability during operation. The collapsible ladders provide additional stable access points when not in use, ensuring the platform remains reliable while allowing necessary mobility.

AI summary
A first platform is mounted to a central riser that is configured to flow a fluid into or out of a wellbore. The central riser is fluidically and structurally attached to a wellhead. The first platform is positioned relative to the central riser to allow access to substantially all external portions of the central riser from the first platform. A second platform is positioned above and supported by the first platform. The first platform is positioned between the second platform and the wellhead. The second platform is movable relative to the first platform.
