ANTIFOULING COMPOSITIONS AND THE RELATIONSHIP BETWEEN HULL SURFACE ROUGHNESS AND FUEL CONSUMPTION

Where roughness on underwater areas of the hull has increased during service, it has been found that re-blasting and fresh coatings will result in immediate and dramatic savings in fuel costs in the region of, say, 10%. It is possible to substantially maintain this saving for 10 years or more provided that damaged surfaces are prepared properly and application of coatings carried out efficiently. Correct selection of anti-corrosive systems for "making good" is vital. The effective thickness of antifouling coatings is discussed. Epigrip Epoxy Coal Tar Heavy Duty primers and Resistex Vinyl Modified Coal Tar provide the necessary base to which high-performance antifoulings can effectively adhere and provide long-term protection against corrosion.
