Abstract
An upright tank-based propulsion assistance rotor sail system is proposed. The system may include an upright tank fixed to a hull of a ship, and a rotor sail in a form of a cylindrical shape having a length and diameter greater than or equal to the upright tank, and installed to surround part or all of an outer circumferential surface of the upright tank. The rotor sail may be rotatably installed while surrounding the upright tank concentrically with the upright tank, and may be movable along a height direction of the outer circumferential surface of the upright tank to maintain a predetermined height. In addition, a vessel equipped with the upright tank-based propulsion assistance rotor sail system is proposed. The fuel tank may be installed to stand upright on the vessel so that the rotor sail is installed to be movable in the vertical direction.
