Damages induced typhoons have been increased and super-typhoons have occurred frequently. In our study, we propose a storm risk assessment technique based on CFD for the industrial structures and equipment located in the coastal regions. Inflow wind speeds are obtained through the information of geography and meteorology in considering regions before pressures of wind-environment and structures corresponding to different winds are calculated with wind speed multiplier and pressure coefficient. The results are applicable to evaluate a warning wind speed or regions vulnerable to debris in a considering region and to examine the safety of structures and their exteriors.

The LPG station's explosion at Bucheon city was a major accident which with rare frequency of occurrence but large damage effect. Therefore, to prevent similar accident in the future from LPG chargings stations which located at inner urban area, it needs to identify the damage effects of such facilities by comparing theoretically quantities risks-PHAST. The BLEVE effects from the accident showed similar level in case of heat flux, however, the over pressure level reflected at reduced distance. The structure damage to the nearby area showed comparatively large reduction of concrete strength and shape changes through by heat effect while the overpressure effect was small.
