Abstract
The LNG (Liquefied Natural Gas) fueled ship is one of the solution to solve the emission of SOx and NOx in conventional maritime fuel. Despite the advantages, the LNG fuel is more dangerous due to their low flash point. The leakage of gas fuel is one of the threat of LNG-fueled vessel, due to its explosive characteristic. This study aims to establish the exclusion zone due to LNG dispersion. The analysis contained the potential leakage and gas dispersion along to the exposed area. A verified Computational Fluid Dynamics (CFD) analysis based on the time accuracy assumption using KFX software was performed to simulate the dynamic behavior of the vapor dispersion. The scenarios were categorized by the leak size, leak location, and mass flow rate. The required environment parameters, e.g., wind speed and wind directions were also considered. It is found that the behavior of dispersed vapor was strongly depending on the leak location and mass flow rate. Surprisingly, the environment parameter has slightly affected the distance of the vapor dispersion. According to these findings, to deliver risk mitigation in a gas leakage accident, the exclusion zone was provided.
