Abstract: An arrangement is disclosed for supplying propulsion power to a contra rotating propellers (CRP) propulsion system in a marine vessel, which arrangement can include a first propeller driven by a rotating power unit, and a second propeller driven by an AC motor. The second propeller can be rotated in an opposite direction relative to the first propeller, wherein an AC generator is driven by the rotating power unit and the AC generator is electrically connected to the AC motor. The rotation speed of the second propeller is between for example 95% and 150% of the rotation speed of the first propeller. The AC motor and the AC generator have the same electrical frequency. The pole number of the AC generator is from for example 2 to 40 and the pole number of the AC motor is from for example 2 to 40.

Abstract: An exemplary propulsion arrangement is disclosed which includes two propulsion units situated side by side at the stern of a ship at opposite sides of a center line of the hull of the ship. Each propulsion unit can include a hollow support structure attached to the hull, a chamber attached to the support structure, an electric motor within the chamber, a propeller connected through a shaft to the electric motor, and a pivotably supported rudder at the rear end of the chamber. Each propulsion unit can be mounted in a toe-out position forming a horizontal tilt angle (β) of 0.5 to 6 degrees to the center line (CL) of the hull.
