Coatings & Corrosion Control for the entire vessel has been fully (and optimally) adopted, savings of up to two percent of total vessel value can be made," says Keasberry. Giving the Slip to Marine Life In the last century, the maritime indus- try discovered that anti-fouling coatings could prevent the buildup of marine life on ship hulls. Such marine life like bar- nacles and algae, slowed the ship and clogged suction intakes and overboard discharges, and required periodic dry- docking for hull cleaning. For similar reasons, power plants and other industri- al applications used anti-fouling paints to keep intakes and discharges clear from marine life buildup. In the North American Great lakes, for example, the introduction of the invasive zebra mus- sels has caused extensive damage to shipping and industry due to the clog- ging of pipes and the resulting reduced efficiencies. A hull covered by marine life may consume up to 30 percent more fuel to cover the same distance in the same time. Most of these anti-fouling paints con- tained biocides, or compounds that leached out of the paint to deter the growth of marine life. One of the main ingredients in such coatings has been tin in the form of Tributyl Tin Salts (TBT). While TBT worked well, it was found to cause deformities in oysters and other shellfish. Further investigation showed that TBT was toxic, and subsequent reg- ulations and legislation have virtually and universally banned TBT. The ship- ping industry understood and accepted the ban, but still had a need for an antifouling paint. Marine plants and organisms need a surface to adhere to, so it stands to rea- son that it would be more difficult for marine life to bond to a very smooth sur- face. The advantages to a hull that is free of marine life, and ultra-smooth and slip- pery, are obvious. Ships can get more speed for the horsepower, and use less fuel and horsepower to achieve speeds. The disadvantages are a relatively high initial cost, and the fact that as a system, one or more sub coats of anti-corrosive coatings must be applied first. Brown says the elastomer coating is environ- mentally friendly, efficient and econom- ical. Super io r{Mater i al s, Superior Craftsmanship, SUPERIOR BOATS.
