Abstract: Considering the temporal and spatial evolution of fire in offshore platform corridor and personnel emergency evacuation behavior, a dynamic evaluation method for personnel evacuation consequences of fire accidents was proposed, and the influence of the changes of heat release rate and soot yield on the injury consequences of evacuees was explored. The results show that the increase of heat release rate leads to the increasing of temperature and radiation values near the fire source, which directly leads to the increase of injury values and death probability of evacuees. The change of soot yield will affect the evacuation speed of personnel, and then affect the exposure time of personnel in the fire hazard, and indirectly affect the casualties of personnel evacuation. Finally, according to the consequences of casualties, the evacuation danger area is identified.

Key words: offshore platform, dynamic evaluation method, temporal and spatial evolution of fire, emergency evacuation
