The invention relates to an installation construction method for a fan installation ship and the fan installation ship. The theoretical leg insertion range is determined according to geological data, and all the pile legs are lowered to the seabed surface and then sink by means of self weight, so that the pile legs are preliminarily in place. The pile is actively pressed for the first time, and pressure is maintained after staged loading of the pile leg, so that soil around the pile leg restores a stable state, and the settling stability of the pile leg is improved. After the platform of the fan installation ship is lifted, the weight of the fan installation ship is basically borne by the pile legs, at the moment, secondary active pile pressing enables the pile legs to be further compacted and pierce into a hard layer, and the bearing capacity is improved. Active pile pressing for the second time is achieved through staged loading of diagonal pile legs, it is guaranteed that the ship body is stressed symmetrically, and meanwhile stable transition from a soft layer to a hard layer can be dealt with; and the pressure is maintained until no further settlement exists, so that the pile leg insertion depth meets the theoretical leg insertion range. According to the method, through theoretical leg insertion range pre-judgment and two different graded loading and pressure maintaining stability, the method adapts to complex seabed geology, and the installation positioning construction reliability of the fan installation ship is improved.
