The invention provides a method for rapidly detaching and tying back temporary buoy tying rigging of tension legs. The method includes the following steps that 1, two buoys are arranged on the tension legs; 2, a temporary traction device is hung on the two buoys in advance; 3, the two buoys are tied and pulled till a designed interval is formed between the two buoys, and the buoy tying rigging device is hung to the position of a lifting lug of the second buoy; 4, a floating crane hook is lowered so that the applied load between the two buoys can be transferred to the temporary traction device; 5, the temporary traction device is hung to the predesigned position of the second buoy; 6, the buoy tying rigging device arranged on the two buoys is detached rapidly; 7, the buoy tying rigging device arranged on the two buoys is tied back rapidly. By means of the method, the problem of mutual collision between the tension legs due to influences of wind, waves and flows can be solved, the temporary buoy tying rigging of tension legs can be detached and tied back timely under a diverse ocean environment, and construction efficiency and reliability are greatly improved.
