Ship fire modelling and evacuation simulation in navigation tunnel
Highlights A method to assess the safety evacuation in navigation tunnels is proposed. A way of determining the critical velocity in ship tunnel is presented. Safety egress times are calculated based on simulations of ship fire and evacuation.
Abstract Navigation tunnels are an essential part of inland shipping networks and play a vital role in enhancing the efficiency of navigation. Ships require a significant amount of time to pass through a navigation tunnel owing to safety speed limitations. If a ship fire accident happens in a confined space inside a navigation tunnel, people on board the ship cannot evacuate quickly on account of the high freeboard of the ship. The accumulated fire smoke poses a significant risk to human lives and can even be fatal. Currently, research on navigation tunnels are rather few, none of them has discussed the safety evacuation under ship fire scenarios. In this study, the Gou Pitan navigation tunnel is used as an example, the safety assessment of evacuation is realized by the simulation and calculation of safety egress time, then, a general method to quantitatively assess the safety of evacuation during ship fire accidents in navigation tunnels is proposed based on the analysis results. This study fills the gaps in the relevant research, and the assessment results can be used to develop the ventilation strategies during emergency evacuations, furthermore, provide a theoretical reference for the safe operation of navigation tunnels.
