Internal corrosion in wing tanks of a tanker ship, the SS R. E. Wilson is estimated to cost $125,000 annually. Corrosion mechanisms are described in terms peculiar to the operation of this ship. Various counter measures are considered, including coatings, inhibition of cargo and ballast, use of inhibited fresh and sea water, changes in Butterworthing schedule, cathodic protection with and without concurrent inhibition. Both laboratory and in-service tests are reported for numerous mitigation methods. It has been established tentatively that the best solution for this ship is concurrent inhibition of cargo with an oil-soluble inhibitor and treatment of empty tanks with a soluble-oil inhibited salt water wash. Reduction of corrosion up to 75 percent is expected with a net annual saving on the order of $65,000.
