Abstract:

This report presents the results of part of a study being conducted to determine the amount of coating deterioration on pilings in coastal areas. The 15-year study will consider the effects of sacrificial cathodic protection, temperature, and geography on coating deterioration in seawater. Results will be used to optimize coating selection. The first annual inspection of the pilings at Buzzards Bay, MA, was conducted from 24 to 28 July 1975. The inspection consisted of a visual evaluation of the piles and electrical measurements of the cathodic protection indices and corrosion potentials of the piles. The piles have developed slight biofouling in the tidal zone. Light guano covers the top 5 to 6 ft 1.5 to 1.8 m of the pilings. Visual inspection of the piling areas above the water determined that all the piles had a rating of 10 according to ASTM G10-68 standards. Only one coating, system No. 12, suffered installation damage. All piles with sacrificial anodes showed adequate protecting potentials.
