Lateral thruster for a vessel

1. A lateral thruster for a vessel comprising a housing, at least one electric motor mounted in the housing, and at least one transverse propeller acting transverse to a longitudinal axis of the vessel, the lateral thruster also includes at least one longitudinal propeller acting in a direction of the longitudinal axis of the vessel, and the longitudinal propeller is driven by the same electric motor as the transverse propeller, wherein the transverse and the longitudinal propellers are each connected to the electric motor and arranged to be separated from the electric motor by a respective coupling.

2. The lateral thruster according to claim 1 , wherein there are at least two of the electric motors and the transverse propeller and the longitudinal propeller are each driven by separate ones of the electric motors, respectively, wherein both the electric motor for driving the transverse propeller and also the electric motor for driving the longitudinal propeller are arranged in the housing.

3. The lateral thruster according to claim 1 , wherein the transverse propeller is supported by the housing.

4. The lateral thruster according to claim 1 , wherein the transverse propeller is arranged in a passage channel extending through the housing and transverse to the longitudinal axis of the vessel.

5. The lateral thruster according to claim 1 , wherein the longitudinal propeller is supported by the housing.

6. The lateral thruster according to claim 5 , wherein a shaft on which the longitudinal propeller is arranged is supported so that the shaft can rotate in the housing or in a part connected rigidly to the housing.

7. The lateral thruster according to claim 1 , wherein a ring-shaped casing surrounding the longitudinal propeller is mounted on the housing.

8. The lateral thruster according to claim 1 , wherein the housing is mounted on a hull in a stationary arrangement external to the vessel.
