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. ## Claims ### Claim 1 A marine wind power generation floating body that is to be coupled to a tower used for wind power generation and is to be installed on the sea, comprising: a floating main body having a predetermined length and 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 having a diameter greater than an outer diameter of one side of the floating main body; and a pitching/rolling damping part positioned on the other side of the floating main body to damp a horizontal pitching and rolling of the floating main body, wherein the pitching/rolling damping part is positioned above the floating main body when the floating main body stands on the sea, the pitching/rolling damping part comprises at least three damping members radially arranged outside the floating main body, and the at least three damping members are positioned at a water plane when the floating main body stands on the sea, wherein each of the at least three damping members comprises a hollow liquid accommodation part, the pitching/rolling damping part further comprises at least three flowage members configured to connect two adjacent damping members among the at least three damping members, at least three liquid accommodation parts communicate with each other through the at least three flowage members, all of the at least three flowage members are positioned at the lower ends in longitudinal directions of the damping members, liquid for damping action on the horizontal pitching and rolling of the floating main body is accommodated in the at least three flowage members and the at least three liquid accommodation parts, the liquid positioned in the at least three damping members is freely flow through the at least three flowage members, as an extra space in which the liquid is not disposed is provided in the damping member, when the floating main body is inclined to one direction, a liquid accommodation amount of the liquid accommodation part disposed at the inclined direction is greater than that of the rest liquid accommodation part, and when the floating main body is inclined to the other direction, a damping action on the inclination in the other direction in the liquid accommodation part, in which the liquid accommodation amount increases, further increases, the marine wind power generation floating body has a center of gravity positioned lower than a center of buoyancy as a draft depth increases when the floating main body stands on the sea, wherein the floating main body further comprises a protruding damping part positioned between the ballast part and the pitching/rolling damping part, the protruding damping part has an outer diameter greater than the outer diameter of one side of the floating main body, and the protruding damping part comprises a tapered portion formed on one of one end and the other end in a longitudinal direction thereof and having an outer surface inclined to the longitudinal direction. ### Claim 2 (depends on 1) The marine wind power generation floating body of claim 1, wherein the at least three damping members are provided in four; the four damping members are arranged with an equal distance; and each of the four damping members has a cylindrical shape having the same diameter. ### Claim 3 (depends on 1) The marine wind power generation floating body of claim 1, wherein the floating main body comprises: a first wall and a second wall, which are spaced apart from each other in a radial direction thereof and each of which has a cylindrical shape having a predetermined diameter; and an auxiliary ballast positioned between the first wall and the second wall. ### Claim 4 (depends on 3) The marine wind power generation floating body of claim 3, wherein the auxiliary ballast is formed with a ring shape along a circumferential direction of the floating main body. ### Claim 5 (depends on 3) The marine wind power generation floating body of claim 3, wherein the first wall forms an outer surface of the floating main body; and the ballast part is positioned inside the second wall.
