Summary of Experimental Piling Inspections at Pearl Harbor, Hawaii
Abstract
Two hundred seventy-three treated Douglas-fir and southern pine piling were installed at Pearl Harbor, Hawaii from 1963 to 1966 and periodically inspected to determine cross-sectional area loss caused by teredine, limnorian, and pholad marine borers. All piling treated with creosote and copper-nickel sheathing, chlordane, creosote and dieldrin, basic zinc sulfate, and most piling treated with an arsenical salt and creosote (dual treatment) have sustained little loss. Piling treated with phenylmercuric oleate in creosote or with copper oxinate have performed relatively well. Arsenical salt treatments (at low retentions), treatments of copper naphthenate with creosote, and most creosote treatments are rated fair to good. Two creosote treatment groups have sustained little loss. In general, little or no apparent enhancement of performance was imparted by the inclusion of Victoria green base, tributyltin oxide, or copper sulfate to treatment chemicals tested.
