Over 7000 vessels have been internally coated in over 16years. Disbributed by: Coating Systems & Supply 800-867-3127 www.royalcoatings.net those achievable with a biocide-based coating ? typically 50 to 70 µm (2.0to 2.8 mils) for the SIGMAGLIDE system. For comparison with conven- tional antifouling coatings an average hull roughness at application of 125 µm (4.9 mils) is achieved. A recent inspection of a vessel which had been coated withSigmaGlide and then spent two idle months prior to its dry docking showed excellent fouling release per- formance. Beyond this, the vessel eventually sailed from the present dry docking without any paintingrequired. And, it was estimated that the silicone paint fuel consumptionsaving has an average impact of 3-4% in a fleet sailing at average speeds of 15 knots and spending 30% time inport in West Mediterranean and Brazil waters. Consuming about 13,000 tons/year of IFO 380, poten- tial savings could be as much as$200,000 annually. Key advantages of the SIG- MAGLIDE system include the short- est minimum overcoating and refloat- ing times in the market. Additionally, the system allows an extended period for overcoating, ensuring the largest application window is available to the customer and the shipyard. With more than 200 vessels coated with the SIGMAGLIDE system ranging from static vessels (FPSO), low activity ves- sels (shuttle tankers), to high activityvessels (high- speed ferries) PPG is so confident in the performance of the system that it guarantees a fuel savingof 5% (subject to average speed and operational activity of vessel). The system is based on two coats ofepoxy: the first being the primer and the second being an anti-abrasive coating; this is then followed by a tiecoat, SIGMAGLIDE 790, and then a topcoat of SIGMAGLIDE 990. A key advantage is that this two- component system, with the volume solids content of the tiecoat at 79%and the topcoat at 80%, considerablyreduces packaging waste costs and reduced solvent emission at applica- tion.PPG?s Sijmen Visser told MarineNews this month that the lat-est offering from PPG comes not only from a wealth of PPG research and development work but also the feed- back from customers. The combined efforts, he says, have paid off. Visser explains that the most important things that an operator should belooking for in a marine coatinginclude not only fuel savings, but alsorobustness of the coating (ease of application and performance in serv- ice), reliability of the coatings organi- zation and supplier and ? in what hecalls the ultimate end-game for cus-tomers ? a biocide free paint. HULLSPEED 3000-S ERIESAlso with an entry into the quickly expanding world of eco-friendlymarine hull coatings is HullSpeed , adivision of New York-based Greenfield Manufacturing Incorporated. The HullSpeed prod- uct line was developed in 2002 and includes performance coatings and finish topcoats for marine craft, air-craft, automotive and construction applications in the industrial, racingand consumer markets. HullSpeed coatings are green products, contain no anti-fouling agents and are fully cured epoxy silicone paints that hard- en to create pro-environment, high performance services. Recently, a 65? passenger ferry oper- ated by the Potomac Riverboat Company was coated with HullSpeed 3000-Series. The Alexandria, VA based boat was hauled for its regular coast guard inspection and will be receiving routine maintenance including new bottom paint.
