CORROSION STUDIES OF STEEL PILING IN SEA WATER IN BOSTON HARBOR

George L. Wey

Abstract


A vital problem which has resulted from our present economic justification of the use of steel piles in all of the Port's waterfront terminals is the corrosion of the piles in sea water. The selection of some type of steel piles was not made on the basis of greater resistance to fire and marine organisms, but for purely economic reasons. Timber piling has its marine borer problem, and steel has its corrosion. In this article there are three thoughts which I hope to convey to every engineer engaged in coastal engineering, namely:
(1) Each project's corrosion consideration should be treated as a distinct and separate study in designing a pile-supported structure, based on investigation of adjacent local conditions.
(2) There is nothing universal about the pattern or rate of corrosion to be expected; it is subject to many variables.
(3) Provisions or measures to mitigate or eliminate corrosion should have economic justification consistent with the planned life expectancy of the study.
