Offshore wind power installation platform

The invention discloses an offshore wind power installation platform. The offshore wind power installation platform comprises a main hull, lifting devices, four spud legs, a spud-around type crane, aliving building and a driving control room. The four spud legs are arranged on the main hull, and each spud leg is connected with the main hull through the lifting devices. The offshore wind power installation platform is characterized in that the main hull is of an axisymmetric structure and the central axis of the main hull is arranged in the ship length direction; the four spud legs comprise the first spud leg located at the stern of the main hull, the second spud leg located at the bow of the main hull, the third spud leg and the fourth spud leg, wherein the third spud leg and the fourth spud leg are located on the two sides of the main hull, the first spud leg and the second spud leg are both located on the central axis, the first spud leg and the second spud leg are located on the midperpendicular of the connected line of the third spud leg and the fourth spud leg, and the first spud leg and the second spud leg are located on the two sides of the connected line of the third spudleg and the fourth spud leg correspondingly; and the spud-around type crane is arranged on the position of the first spud leg, and the living building and the driving control room are located at the bow of the main hull. According to the offshore wind power installation platform, through arrangement of the four spud legs, the spud-around type crane, the living building and the driving control room, the deck use ratio of the wind power installation platform is increased, and meanwhile balancing of hull loads is facilitated.
