Abstract
The present application relates generally to a control arrangement for controlling at least two azimuthing propulsion units of a ship. The control arrangement comprises a crash stop activation member for activating a crash stop procedure, after which the crash stop procedure is executed in which the orientation and propulsion speed of the azimuthing propulsion units are controlled until the propagation speed of the ship has at least been reduced from the moment when the crash stop procedure was activated.
Claims19
A control arrangement for controlling at least two azimuthing propulsion units of a ship, comprising:
- one or more levers for controlling the at least two azimuthing propulsion units separately or jointly;
- a crash stop activation member for activating a crash stop procedure;
- means for performing the crash stop procedure in which the orientation and propulsion speed of the azimuthing propulsion units are controlled until the propagation speed of the ship has at least been reduced from the moment when the crash stop procedure was activated by the crash stop activation member, wherein the control arrangement is configured to adjust the crash stop procedure, by adjusting orientation and/or propulsion power of at least one azimuthing propulsion unit according to an operator control gesture received on the one or more levers during the crash stop procedure.
A method of performing an emergency stop of a ship having at least two azimuthing propulsion units, the method comprising:
- receiving an input from an operator of the ship that a crash stop procedure is to be started;
- and
- performing a crash stop procedure to automatically control the at least two azimuthing propulsion units for stopping of the ship, said performing comprising:
- receiving a control input via a manual controller for controlling a course of the ship during the crash stop procedure;
- and
- adjusting the crash stop procedure such that at least one of the orientation and the propagation power of at least one azimuthing propulsion unit diverges from the respective values determined by the crash stop procedure.
