Segmented Pressure Vessel Support Structure for Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manufacturing of large and heavy pressure vessels is challenging due to the difficulty in accessing and commissioning apparatus within the vessel, which requires significant resources and extends manufacturing time, especially when traditional lifting equipment is inadequate or access is limited.
Innovation Solution
A method involving the division and re-assembly of pressure vessel sections with apparatus fitted between them, utilizing a support structure that allows for independent movement and reattachment of segments, enabling quicker and safer assembly with reduced risk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If apparatus is installed inside the pressure vessel during traditional manufacturing, then the pressure vessel can be assembled, but access for commissioning becomes difficult and manufacturing time extends
Solution Approach 1:
The pressure vessel is divided into multiple sections that can be assembled separately with apparatus installed in accessible positions, then joined together. This segmentation allows commissioning personnel to access the apparatus during assembly rather than working within the confined enclosed space of a complete vessel.
Solution Approach 2:
The apparatus is installed and preliminarily commissioned in the assembled sections before the sections are joined to form the complete pressure vessel. This preliminary action allows commissioning to occur when access is easier, avoiding the need to work inside the enclosed final structure.
2Ease of manufacture
If traditional lifting equipment is used to install apparatus, then standard procedures can be followed, but the equipment capacity is inadequate for large and heavy apparatus
Solution Approach 1:
The pressure vessel is segmented into sections that can be handled by standard lifting equipment. The apparatus is installed in these smaller sections where lifting capacity requirements are reduced, avoiding the need for specialized heavy-lifting equipment while maintaining the ability to install large apparatus.
3Reliability
If significant additional equipment and personnel are provided for commissioning, then safe working practices can be adhered to, but device complexity and resources increase
Solution Approach 1:
Commissioning is performed on segmented sections with apparatus in accessible positions rather than inside the enclosed complete vessel. This reduces the need for specialized equipment and personnel while maintaining safety, as standard commissioning procedures can be followed in the open assembly environment.

AI summary
A support structure for manufacturing a pressure vessel, the support structure configured to be carried on a supporting substrate, the support structure comprising a first segment support structure nestable within, and moveable relative to, a second segment support structure, wherein the first segment support structure is configured to be raised and lowered relative to the second segment support structure to thereby raise and lower the first segment relative to the substrate, and the first segment support structure is configured to move between a nested position within the second segment support structure to a position spaced apart from the second segment support structure across a surface of the substrate.
