Assisted dynamic position control of a charging vessel

Abstract

A method for adaptive dynamic positioning of a vessel during offshore charging from a power station, actively assisted by a cable management system, the method comprising the steps of: (i) establishing a control link between said cable management system, configured to control at least one characteristic parameter of a charging cable connected between the power station and the vessel, and a positioning control system, configured to control a propulsion system of the vessel so as to move the vessel relative to the power station; (ii) defining, relative to the power station and based on said at least one characteristic parameter of said charging cable, a first target zone, adapted to effect vessel movement (response) of a first type, and at least one second target zone containing said first target zone, adapted to effect vessel movement of at least one second type; (iii) monitoring any one of said at least one characteristic parameter of said charging cable, at least one performance parameter of said propulsion system, a vessel position and/or a vessel heading) relative to the power station, and at least one environmental parameter; (iv) selectively modifying said first target zone and/or said at least one second target zone in response to a predetermined change of any one of said at least one characteristic parameter of said charging cable, at least one performance parameter of said propulsion system, said vessel position relative to the power station, and said at least one environmental parameter; (v) controlling said positioning control system and said cable management system, so as to maintain the vessel within or move the vessel back towards said first target zone in accordance with said vessel movement of a first type and said vessel movement of a second type, respectively.
