A linear motor has a stator body securely attached to a marine floating structure and a movable body acting as solid mass. In response to a command signal from a controller which phase-controls a signal from rocking-motion sensor, the movable body is forced to move in a direction of reducing the rocking motion against the floating structure in rocking motion, so that the rocking motion of the marine floating structure is reduced or suppressed.
