Finally, the buckle at the rear end of the main body is aligned and buckled as shown in fig. 6 and is fastened by a steel wire connected to the anchor rope. The packed whole is placed on shore or in storage, either straight or folded again. The resistance anchor is connected with the other end of the anchor line, is arranged on one side and ensures that the remaining length of the anchor line is properly folded or curled.

When oil spilling occurs in emergency, the towing belt is used for connecting the oil containment boom distribution bag and the stern, and the resistance anchor is arranged on the ship deck. The ship exits from the wharf and brings the folded oil containment boom into the water together with the cloth bag. Due to the design of the arrow-shaped foam floater and the triangular head, the head of the oil containment boom cloth bag keeps a horizontal posture with the pointed end upwards when being dragged in water. Thus, the ship can not bear huge resistance because the head of the oil containment boom distribution bag is submerged in water when running. When the ship runs, the ship is dragged by the three reinforced reinforcing belts, and the pulling force is averagely acted on the front section of the oil containment boom distribution bag, so that the fracture of the connecting point of the dragging belt and the distribution bag is avoided.
