On the occasion of the National Association of Corrosion Engineers’ Annual Conference in Cincinnati in April, 1949, the Salt Water Corrosion Symposium provided an opportunity for the discussion of the problems of corrosion and protection of steel piling with particular reference to structures of offshore drilling rigs.
The principal discussion stemmed from the paper by H. A. Humble entitled “Cathodic Protection of Steel Piling in Sea Water” which was published subsequently in the September, 1949, issue of Corrosion, Vol. 5, No. 9, p. 292. That publication included also a discussion by G. C. Cox with particular reference to effects of cathodic coatings, and by C. P. Larrabee and the present author of some of the details of Humble’s observations of the distribution of corrosion of steel partially immersed in sea water and of the powerful local cells set up between the continuously immersed and intermittently immersed surfaces in...
