The invention discloses a method, a system and a device for predicting the speed of a ship to the ground, and a storage medium. The method comprises the following steps: acquiring ship pool experiment data, historical ship navigation data and ship navigation environment data; then, according to the ship pool experimental data, constructing a ship still water speed prediction model; according to the historical ship navigation data and the ship navigation environment data, constructing a ship to-ground speed prediction model; then, ship navigation data and navigation environment data are collected; and inputting the ship navigation data and the navigation environment data into the trained ship to-ground speed prediction model to obtain the predicted ship to-ground speed. According to the method, prediction of the speed of the ship to the ground under complex environmental factors is achieved, data support is provided for follow-up navigation, collision avoidance and other operations, and meanwhile the method ca
