Corrintec (UK) has developed system to combat corrosion of waterjet systems. Growth in the world fleet of waterjet-fitted fast ferries has spurred closer attention to potential problems of corrosion of the hull surfaces adjacent to the propulsion appendages.
Drawing on its extensive experience in the military craft sector, Winchester-based Corrintec has developed impressed current cathodic protection (ICCP)-based solutions to combat corrosion in waterjet systems and thruster tunnels in high-speed commercial vessels with aluminium and steel hulls.
'Bi-metallic corrosion can be a problem where stainless steel waterjet components are used in aluminium-hulled craft, although many other factors also influence corrosion,' said David Moran, Corrintec's technical development consultant engineer. The ICCP method is claimed to be the most cost effective solution offering the added benefits of low weight and low profile.
