Abstract: The Navigation tunnels are a new type of navigational passage with the features of narrow channel, shallow water, dim light and isolated environment. To safely navigate through a tunnel is a challenging task and the navigators will experience high pressure. Few research on tunnel navigation has been conducted. Research on Navigating the tunnel in Siling Route Number 2 of Wujiang River under planning is conducted. The navigational handling procedure, stopping maneuvering process and small ruder angle maneuverability of typical ships are simulated with a marine simulator. The scheme for navigating through the tunnel is proposed.
