Abstract

To understand the influence of staircase layout on the evacuation efficiency of passenger ships, a passenger ship evacuation simulation model is established by using FDS+EVAC based on the survey results of the population composition and the familiarity of the ship of the Ro-Ro passenger from Yantai to Dalian. The evacuation time and evacuation efficiency were calculated by setting different staircase layout scenarios. The results show that increasing handrails at the main staircase of passenger ships can effectively disperse the flow of evacuation, enhance the efficiency of evacuation at the main stairs, and ease congestion phenomenon. However, too many handrails in the main staircase will increase the overall evacuation time. Considering the construction cost and the personal walking convenience, it is suggested to increase one handrail to the main staircase. The passenger ship evacuation model established in this paper can be used to identify the congestion points of the existing passenger ship geometry layout, optimize the design of ship staircase, and improve the efficiency of passenger evacuation.
