1972 Inspection of Experimental Marine Piling.
Abstract
The 54 Cooperative piles at Coco Solo, Canal Zone, and the 267 Cooperative and NCEL experimental piles at Pearl Harbor, Hawaii were inspected during the periods February 22 to 25 and March 17 to 24, 1972, respectively. After 9 years of exposure at Coco Solo, 11 of the 12 piles treated with 70/30 creosote-coal tar showed borer attack of varying degrees of severity. Only minor attack was noted on 7 of the 18 dual-treated piles. Six (6) of the 12 piles treated with 70/30 creosote-coal tar showed light borer attack at Pearl Harbor but only trace attack was noted on 5 of the 18 dual-treated piles. The major attacking organisms in both sites was Martesia. After 5 to 8 years of exposure in Pearl Harbor, 60 of the 201 NCEL piles have shown evidence of borer attack. (Author)
