[Abstract]:Based on the existing problems in the original smoke exhaust design scheme of a platform on the sea, the smoke exhaust design scheme was optimized. The simulation of the platform's high-temperature smoke diffusion and operation conditions under different environmental conditions was carried out by using CFD software. The distribution range of flue gas temperature and harmful gas concentration is analyzed. Combined with CAP 437 code and the limit value of human exposure to harmful gas, the unserviceable probability and harmful degree and probability of harmful gas concentration caused by the rise of temperature for helicopter take-off and landing are calculated. Finally, the measures to mitigate the harm of high temperature flue gas and the suggestions for smoke exhaust design are discussed. The results of this study can provide a reference for the design of high temperature smoke exhaust on offshore platform.
