An arrangement for steering and supplying propulsion power to a contra rotating propeller(s) (CRP) propulsion system in a marine vessel is disclosed. The arrangement can include a first propeller, a second propeller driven by an AC motor, and an AC generator. The AC motor and AC generator can have the same electrical frequency. Another electrical power source can be electrically connectable to the AC motor in parallel to the AC generator. A shaft of the second propeller is mounted rotatable in a support structure which is attached to a hull of the marine vessel, and a rudder is supported in a manner allowing pivotal movement of the rudder relative to the support structure. |
