The invention belongs to the technical field of ship energy consumption prediction, and particularly relates to a ship energy consumption prediction method based on data driving. The method comprisesthe following steps: acquiring an expected ship route, departure time and sea condition information of a ship; constructing an offline basic model which comprises a ship-to-water steady-state navigational speed model, an engine power model and an engine oil consumption model; performing high-dimensional linear interpolation on discrete grid matrixes of the ship to the water steady-state navigationspeed model and the engine power model; carrying out one-dimensional linear interpolation on the discrete grid matrix of the engine oil consumption model; and deducing a ship energy consumption modelin real time. According to the method, a set of data matrix is used as support, rapid calculation of the energy consumption of the long route of the ship is achieved, and the data matrix in the method can be obtained in various modes and is convenient and rapid to replace. According to the method, the thought of an original ship dynamics simulation model is not influenced, and the method and thedynamics simulation model coexist in an actual simulation verification and evaluation system and are respectively responsible for different types of simulation calculation.
