The invention relates to a water traffic risk assessment method and device, computer equipment and a storage medium. The method comprises the following steps: using a focusing superposition means foracquiring a plurality of risk coefficients in the target water area, wherein the plurality of risk coefficients comprise a ship density risk coefficient based on the ship field, a traffic conflict risk coefficient based on the ship field, a vector kinetic energy risk coefficient and a special cargo carrying risk coefficient; according to the historical accident analysis data of the target water area, performing parameter calibration on the calculation model of each risk coefficient in the target water area to obtain a corresponding risk coefficient; determining a weight parameter of each riskcoefficient in an accumulative superposition model, wherein the accumulative superposition model is used for calculating a traffic risk value in the target water area; and finally, determining the traffic risk level in the target water area according to the traffic risk value in the target water area. By adopting the method, the accuracy of water traffic risk assessment can be improved.
