Cathodic Protection/Partial Coatings Versus Complete Coating in Ballast Tanks-Five Year Report

Abstract

Ship ballast tanks are one of the most costly items of new ship construction. In addition, ballast tanks are one of the most severe corrosion areas during ship operations. The SP-3 Panel of SNAME recognized these problems and selected a research and development project to investigate alternate, cost effective corrosion control solutions. Four approaches were originally selected for mock-up ballast tank testing and 20 year life cycle cost analysis. A new coating system was added after three years. * Completely coated tanks with high performance coating * Partially coated tanks with cathodic protection * Preconstruction primer with cathodic protection * Soft coatings with cathodic protection * Rust tolerant epoxy coatings(Added after three years).
