    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 depending on situations 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.

    Abstract: The present invention provides a ship mooring device using a spring bellows structure, wherein the ship mooring device temporarily or permanently fixes a state in which the ship is spaced at a preset distance from a vessel or a pier, the ship mooring device including: a main body configured of a plurality of frames in which opposite ends of each of the frames are hinge-coupled to facing ends of adjacent frames to form foldable hinge joints, wherein diagonally opposed non-adjacent hinge joints of the frames are fixed to the ship and the pier, respectively; and a plurality of wires which are installed inwards in diagonal lines with respect to the frames of the main body to connect the diagonally opposed non-adjacent hinge joints together, with an elastic member interposed in a center portion of the radially disposed wires to generate predetermined dynamic stability when the ship is moved.

    Abstract: A multiple oscillating water pumping device includes: a wing member disposed in fluid to generate a lifting force using the flow energy of the fluid; a rotation device to reciprocally rotate the wing member to periodically change the direction of the lifting force acting on the wing member; an arm is rotatably coupled to the wing member, the arm being reciprocally rotated about a pivot shaft by the lifting force acting on the wing member; and a cylinder where fluid enters and exits according to the internal pressure that is periodically increased and decreased by the reciprocating motion of a piston that is connected with the arm through a connecting rod. The multiple oscillating water pumping device is configured to minimize the supply of a power source required for operation and to minimize the loss of head when pumped water flows toward a reservoir along a conduit.
