Abstract:

In a survey of the corrosion occurring on steel sheet piling at eight Naval harbors a parallel series of samples were cut from three piles at each harbor and the corrosion losses were determined by Laboratory analyses. A technical literature survey revealed additional data on the corrosion of steel sheet piling and the effectiveness of cathodic protection. Investigation showed that the greatest rate of corrosion of steel sheet piling is in the splash zone and at about 2 feet below MLW. The vertical distribution of the intensity of corrosion is the same as that found in the literature. No protective maintenance coatings had been applied from MLW to the top of the pile at any of the eight harbors investigated. Coating piles fully before driving them increases their life, especially from MLW into the mud zone. Cathodic protection has been in use at Puget Sound Naval Shipyard for the last six years and appears to have retarded corrosion of the piling below MLW.
