The invention discloses a ship bridge collision safety risk assessment system comprising a basic data module used for storing basic information of a bridge, a navigation channel and a ship; the navigation clearance evaluation module is used for calling the basic information of the bridge, the navigation channel and the ship in the basic information module, calculating the clearance requirement required by navigation of the ship, calculating the actual clearance of the navigation channel in the bridge, and judging whether the actual clearance of the navigation channel meets the clearance requirement required by navigation of the ship or not; the failure probability evaluation module is used for calling the basic information of the bridge, the navigation channel and the ship in the basic information module, carrying out reachability analysis on the ship of which the actual clearance of the navigation channel meets the clearance requirement required by navigation, carrying out geometric collision probability calculation on the ship meeting the reachability, obtaining a failure probability in combination with the navigation data of the ship, and carrying out geometric collision probability calculation on the failure probability; and analyzing a risk level according to the failure probability. Detailed data support is provided for bridge safety protection, and bridge safety protection is facilitated.
