Abstract: This paper conducts a more in-depth examine for the heave motion of the vessel and active heave compensation with the surge. It is intended to solve the trailing suction hopper dredgers rake tube terminal level height stability. It establishes compensation wave forecasting system, through the movement of ship motion reference unit measuring the vertical velocity and acceleration. The main control unit is combined with Kalman filter algorithm to process data in accordance with the mathematical model established. It adjusts the speed of the rope through the implementing agencies to complete the retractable rake tube terminal control compensation, so that the level of the rake head remains stable during operation. Wave compensation prediction system established with independent learning ability, can use the measured data to improve the accuracy of self-correction, therefore with high practical value.

Key words: active wave compensation, Kalman filter, prediction of wave compensation system
