A series of 4 ships from Rederij Groen, Scheveningen, Netherlands, have undergone corrosion passivation treatment for their ballast water tanks. Aboard ship Marianne G, berthed at Stellendam, the ballast water tanks were treated together with the Marianne G crew and superintendent for training purposes. Three other vessels, Shipping Green’s (RG) Mare Verde, Victory G and Remus, have received the nC Corrosion Passivator – Fluid treatments on board where Shipping Green crews will perform the passivation process themselves.
nC Corrosion Passivator – Fluid is designed to passivate heavy corrosion and remove loose rust without the need for time-consuming sandblasting or sanding. Also, the time-consuming and costly application of (epoxy) coating is not required to protect metal surfaces and structures, as Corrosion Passivator – Fluid is applied by floating (floating), not necessarily by spraying or brushing.
A total of 9 ballast water tanks were treated to prevent further deterioration of the material thickness as the tanks began to corrode. Treatment of the tanks, totaling about 300 m³, was completed in about 8 hours of work, with a crew of three, consisting of Marianne G’s chief engineer and two project engineers.
Corrosion Passivator application averages 6 DB tanks or 6 W tanks per day, depending on the pumping capacity on board the vessel. No dock is required during application, lay-by or even application while underway is possible. Please note that Corrosion Passivator Fluid works without sandblasting and 2C coating. This significantly improves safety and health and keeps the planet clean.
