A study was conducted to determine the extent of galvanic corrosion that would be caused by copper-nickel sheathing of offshore steel platforms. The study investigated the effects of selected steel-to-CuNi area ratios on the magnitude and distribution of the galvanic current. One-year seawater exposure tests using segmented CuNi-steel pilings were conducted near Ocean City, NJ. The results of the study suggest that for piling configurations and lengths of copper-nickel sheathing similar to those included in the study, the maximum galvanic corrosion rate of the steel will be between 0.2 and 0.3 mm/y immediately next to the sheathing. The galvanic attack will be confined primarily to the first few meters of piling near to the sheathing. Beyond this, the intensity of galvanic attack will decline markedly.
