Abstract

Abstract: The paper was aimed at researching emergency evacuation strategies from a vertical ship lift on initial fire to improve the evacuation efficiency. Firstly, the evacuation paths were divided into the horizontal path and vertical evacuation path according to the vertical ship lift structure and the evacuation passageway. Secondly, evacuation speeds were obtained as a function of age. The values of horizontal evacuation time from horizontal corridor to vertical evacuation passage were calculated. Thirdly, the relationships between the locations of ship reception chamber corridor and evacuation floors were studied. The values of vertical evacuation time from vertical evacuation passage to upstream or downstream platforms through stairs or elevator were calculated. Finally, an evacuation time comparison was made between the stairs mode and the combination mode. The results show that the greater the distance between fault height and evacuation point is, the bigger the advantage of using the combination mode will be when a fire occurs in the vertical ship lift.

Key words: emergency evacuation, evacuation strategy, vertical ship lift, initial fire, elevator evacuation
