PURPOSE:To atrain the antifouling of marine structures at low cost by a method in which a water-proof film is adhered to a marine structure before setting it into water, the marine structure is floated and towed on the water surface, and the water-proof film is removed when working. CONSTITUTION:A water-proof film is closely adhered to the portion to be sunk in the water of a marine structure 1 before being sunk, the marine structure 1 is towed on the water surface 2 to a working sea area, and then the marine structure 1 is jacked up to the water surface 2 and the water-proof film is removed. Thus, the operation is made easier and the cost is more reduced than when a water-proof paint is coated on the marine structure. |
