Crane control with active rough sea

Crane control active for a rough sea, arranged on a floating body crane comprising a lifting mechanism for lifting a suspended load by a rope, with a measuring device which determines a current heave movement from sensor data, a prediction device which predicts a future movement of the Lastaufhangepunkts based on the determined current heave movement and a model of the heave movement, wherein the prediction device determines the prevailing modes of heave from the data of the measuring device and creates a model of the swell on the basis of certain prevailing modes, and a path control of the load which compensates by driving the hoisting gear of the crane, due to the projected movement of the Lastaufhangepunkts the movement of the load by the sea state at least partially.
