| Abstract: | Leakage of heavy gas is one of the most dangerous accidents happened on floating production units at sea. The precooling natural gas separating tanks leakage model of different wind speeds and different widths were established in order to research the effect of the leakage, and the diffusion simulation of dense gaseous leakage was modeled based on floating platform. At last advices were given for safety of floating production units at sea. |
