Almost since it first set sail, this 50m High-Speed Feadship yacht, has suffered from paintwork flaking and deteriorating from its two gas turbine exhaust funnels.
Caused by thermal shock from sea-spray hitting the hot funnels, the captain and crew had tried almost everything to solve the problem, from thermal paints to a ‘baking’ method designed for nuclear power stations. All saw the coating begin to lose adhesion, crack or flake within 30 minutes. The crew were required to repaint the funnels each season and touch-up mid-season to keep the funnels looking acceptable.
“We would watch new paintwork flaking off after 30 minutes at sea.”
Rokoat offered its TechShield Thermal Reduction coating.
This product has the ability to resist temperatures of +1000ºC and has colour stability up to 815ºC. Applied inside the funnels it reduced the temperature of the metal, minimising the effects of thermal shock. Rokoat also prepared and repainted the exterior paintwork.
After two seasons with no ’touch-ups’ applied, the captain has reported the paintwork on the funnels is more than acceptable with only the slight paint deterioration that is to be expected of a sea going vessel.
These funnels were a large yearly servicing job, now after two years only minor detailing works are required.
“After so long looking for a solution, I was skeptical when Wayne offered the TechShield product. After two seasons, I can honestly say it does what it says on the tin. It works and surpasses anything we have tried on the market.”
