An object is to provide a floating type wind turbine generating apparatus capable of stably mooring the floating body against the drift force and rotational moment acting on the floating body, and a mooring method of the floating type wind turbine generating apparatus. A floating type wind turbine generating apparatus comprises: a wind turbine generator 10; a floating body including a first column 22a which is disposed on an upwind side in a main wind direction and on which the wind turbine generator is disposed, a second column 22b and a third column 22c disposed on a downwind side with respect to the first column in the main wind direction, and two lower hulls 24 one of which connecting the first and second columns and other of which connecting the first and third columns; a plurality of mooring cables 34 each of which connecting the floating body and an anchor 32 fixed on a water bottom in a catenary curve, wherein at least two of the mooring cables are connected to the first column, at least one of the mooring cables is connected to the second column, and at least one of the mooring cables is connected to the third column, and wherein the mooring cables extend radially from the floating body so as not to intersect with one another in a planar view. |
