ANTICORROSION METHOD AND ANTICORROSION DEVICE FOR MARINE STRUCTURE
PROBLEM TO BE SOLVED: To provide an anticorrosion method and an anticorrosion device for a marine structure, enabling corrosion of a surface of a steel structural member of the marine structure to be inexpensively suppressed.SOLUTION: Water 3 is jet to a surface of a steel structural member 2 of the marine structure, and one or both of temperature of the surface of the structural member 2 and humidity in the vicinity of the surface are regulated in a regulated range by the jetted water 3, thereby concentration and temperature of chloride ion at the surface of the structural member 2 are regulated in a range in which corrosion does not occur, so that corrosion of the structural member 2 is prevented.
【課題】海洋構造物の鋼製の構造部材の表面の腐食を安価に抑制することのできる海洋構造物の防食方法及び防食装置を提供する。【解決手段】海洋構造物の鋼製の構造部材２の表面に水３を噴射して、噴射した水３によって構造部材２の表面の温度または同表面付近の湿度の一方又は双方を規定の範囲内に抑えることで、構造部材２の表面における塩化物イオン濃度及び温度を腐食が発生しない範囲に抑えて、構造部材２の腐食を防止する。【選択図】図３
