Over the last couple of months a number of vessels have had their rudders coated with Ecoshield at shipyards in China. These include several container vessels and a car carrier. The applications will protect the rudders against cavitation and corrosion damage for the remainder of the vessels’ service lives.
Many case studies testify to this success. M/v Maersk Deva came into drydock earlier this year, five years after application. The Ecoshield coating was still fully intact. More recently another container vessel drydocked in Shanghai. The vessel had been sailing with Ecoshield on its rudder for two years and the coating was still in excellent condition. No repaint or even touch-up was required. Other examples of the amazing results obtained with Ecoshield can be found here and here.
Accortding to the manufacturer, the coating provides the rudder with an impenetrable protective layer. At the same time its toughness and flexibility enables absorption of the forces that are produced by cavitation. Ecoshield is also suited for other areas prone to damage, such as propeller nozzles, thruster tunnels, the bulbous bow or stabilizer fins.
