Optimizing LNG Safety: Unveiling Insights and Solutions Through FSI Analysis

Project Background
Our project embarked on a specific mission: to predict the cause of a cold spot and temperature distribution around the 30” BOG Nozzle (N3) on the roof, addressing potential leakage concerns.

Methodology and Approach
In response to the challenge, our team introduced innovative solutions by applying assumptions limited to the affected portion rather than modeling the entire LNG system. Notably, we employed the Fluid-Structure Interaction (FSI) method, encompassing thermal stress directly following heat transfer simulation.

Notable Technologies and Methodologies
A key technological highlight was the application of the Fluid-Structure Interaction (FSI) method, streamlining the heat transfer model and ensuring precise thermal stress representation.

Challenges
The project faced challenges, primarily related to time constraints. Initially focused on structural analysis, the need for additional CFD analysis emerged, necessitating model simplification to align with the project schedule.

Outcome
Calibrating simulation results with field temperature measurements, the project enhanced client awareness of potential leakage areas and their severe consequences. By addressing potential leakage issues, our project equipped the client with a proactive understanding of severe effects, contributing significantly to their operational success.
