Vessel Partition Wall Insulation Bridging Stiffener Gaps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for mounting insulating elements in vessels require complex adaptations to stiffener geometry, increasing production complexity and space requirements, while also necessitating a large number of pins and washers for fixation.
Innovation Solution
A partition wall design featuring a wall sheet with elongated stiffeners spaced at a distance, where an insulation layer is fixed to the protruding ends of the stiffeners, bridging the gap between them to form a cavity, thereby reducing the number of insulation elements and fastening components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If formfitting insulation elements are used to envelope stiffeners, then heat resistance and fire resistance properties are improved, but production complexity and transportation space requirements increase
Solution Approach 1:
The invention extracts the insulation function from complex formfitting elements and relocates it to a simplified insulation layer that bridges only the gap between stiffeners. The stiffeners themselves retain their structural enveloping function, separating structural support from thermal insulation functions.
Solution Approach 2:
The insulation system is segmented into two functional components: stiffeners that provide structural support and partial insulation, and a separate insulation layer that bridges gaps between stiffeners. This segmentation allows each component to be optimized independently and simplifies the overall assembly process.
2Reliability
If multiple insulation elements are used to cover stiffeners, then insulation performance is improved, but the number of fastening elements (pins and washers) increases
Solution Approach 1:
The invention merges multiple separate insulation elements into a single continuous insulation layer that spans across the gap between stiffeners. This consolidation reduces the number of fastening points required from multiple pins and washers per stiffener to a simplified fastening system.
Solution Approach 2:
The insulation layer serves multiple functions simultaneously: it provides thermal insulation, bridges gaps between stiffeners, and acts as a continuous protective barrier. This multi-functionality eliminates the need for separate components and reduces fastening requirements.
3Reliability
If insulation elements are mounted to touch the wall sheet surface, then heat resistance is improved, but installation complexity and effort increase
Solution Approach 1:
The insulation layer acts as an intermediary element that bridges the gap between stiffeners and provides thermal protection without requiring direct contact with the wall sheet. This intermediary approach maintains heat resistance while simplifying installation by eliminating the need for precise positioning against the wall sheet surface.
