An ocean-going vessel comprises a stern power plant and side propulsion units attached to the starboard side and to the port side of the ocean-going vessel. Each side propulsion unit comprises two combined propulsion systems having tubular propellers and magnetohydrodynamic drives. The front and rear combined propulsion systems or the starboard side and the port side are united by a tube. Side propulsion units are adapted to provide additional thrust and maneuverability to the ocean-going vessel. Side propulsion units are adapted to provide braking actions by reversing combined propulsion systems.
