Ten years later, the Intersleek system has only needed touch-up repairs, significantly reducing overall paint volume, packaging, waste and VOC emissions. Because full coats were not necessary, dry-docking time and costs were also significantly reduced.
During Norwegian Sun’s dry dock in the Bahamas in January 2011, it was noted that the Intersleek system had performed well and was in good condition with no animal or weed fouling. Commenting on the performance of the Intersleek system, Mr. Brian Swensen, Senior Vice President, Technical Operations, Norwegian Cruise Line said, “We are very pleased with the performance of the Intersleek system. At Norwegian Sun’s two interim dry-docks, we only applied a total of 600 litres of Intersleek. For a standard antifouling system, we would have used approximately 6,000 litres. This has resulted in a 90% reduction in VOC emissions and a 100% reduction in biocide release. The fact that no full coats were required meant that the dockings in 2004 and 2007 were completed ahead of schedule with lower paint and application costs than expected.”
