Abstract: To predict the dynamic probability of blowout fire on offshore drilling platform,the main factors influencing blowout fire accident were identified using the safety barrier model. Then, a dynamic probability prediction model was built for blowout fire by integrating the relevant principles of SD. The simulation software Vensim was used to simulate the overall process of blowout fire accident, and a dynamic probability prediction formula was deduced for blowout fire by fitting the historical data and simulation data. The results show that there is a exponential functional relation between the probability of blowout fire and time, and a duration of 4 years will make the probability of blowout fire increase from 2.41×10-6 to 3.997×10-6,and that the deduced equation can be used to predict the dynamic probability of blowout fire accident on offshore drilling platform .
