Abstract
There is provided a ship, in particular a cargo ship. It has a plurality of Magnus rotors, wherein associated with each of the plurality of Magnus rotors is an individually actuable electric motor (M) for rotating the Magnus rotor, wherein associated with each electric motor (M) is a converter (U) for controlling the rotary speed and/or the rotary direction of the electric motor (M).
Claims7
A cargo ship comprising:
- a plurality of Magnus rotors positioned on an upper deck of the cargo ship and exposed to receive wind;
- a plurality of individually actuable electric motors associated with and coupled to the respective Magnus rotors for rotating the Magnus rotors;
- a plurality of electrical converters, each associated with each respective electric motor for providing electric power to drive the respective electric motors coupled to the Magnus rotors;
- a subdividable cargo hold, wherein subdivision of the cargo hold is effected by fitting pontoon covers;
- and
- a closable stern gate that is hydraulically driven.
