Coatings are the first barriers to protect vessel hulls against corrosion. Due to microscopic pinhole defects in the coating and damage to it whilst in service localised pitting will occur. Hull/flush mounted anodes are used to complement the coating at areas of exposed steel prolonging the life of the coating. Hull anodes are also employed to reduce corrosion rates on areas of the hull that are local to propellers and the propellers themselves. Alloys of Zinc, Aluminium and Magnesium with the necessary trace elements to provide correct performance are used for the manufacturing of Sacrificial anodes (Aluminium Anodes, Zinc Anodes and Magnesium Anodes). All types of Hull anodes ranging from weld-on to bolt-on types are available upon request.
