Abstract

In a method for assembling a wind power generator, a tower of a floating-type offshore wind power generation device is placed and fixed to a tower standing frame, blades of the floating-type offshore wind power generation device are fixed and stacked on a first mount and a second mount, a carriage is used to move a blade installing structure including a blade assembly table formed on a first side and a blade carrier formed on a second side opposite to the first side, the blade carrier is vertically moved below the blades, the blade carrier is vertically moved to correspond to the height of the blade assembly table in a state in which the blade is gripped by the blade installer, the blade installer is moved from the second side to the first side, and the blade is assembled to a nacelle formed at one end of the tower.

Abstract

A method for installing an offshore wind power generation floating body may include manufacturing a lower structure including a damping plate, a guide beam including protruding portions, and a slot, coupling a temporary buoyancy tank to each protruding portion, installing a concrete block mounting structure in the slot, transporting the lower structure on the sea until a destination by a towing vessel, fixing the lower structure between a first work barge and a second work barge by a link bridge connected to each of the first work barge and the second work barge, and seating a concrete block connected to a second wire of a second crane seated on the second work barge on the concrete block mounting structure in a state in which first wires of a first crane are connected to the lower structure to maintain a tension equal to or greater than a set magnitude.

Abstract

A marine wind power generation floating body according to an embodiment of the present disclosure can be coupled to a tower used for wind power generation and is provided at sea. The marine wind power generation floating body includes a floating main body which is formed at a predetermined length and which has a circular transverse cross section, a ballast part positioned on one side of the floating main body, a damping plate positioned at one end of the floating main body, and formed with a diameter that is larger than the outer diameter of one side of the floating main body, and a pitching/rolling damping part which is positioned on the other side of the floating main body, and which damps the horizontal pitching and rolling of the floating main body.
