Abstract : The cooperative and NCEL experimental piles in Pearl Harbor, Hawaii and the cooperative piles in Coco Solo, Canal Zone were inspected in January and March 1973, respectively. Of the 120 piles that were inadvertently removed from test in August 1972 at Pearl Harbor, about half were redriven in May 1973. They showed that Martesia attack was greatest at the intertidal zone and that Limnoria attack was frequently greatest at the mud line. Cupro-nickel sheathing was severely corroded with large perforations at about the mid-exposure zone. (Author)
