Photograph Descriptions

Application Situation
High speed passenger ferry propulsion units.
Application Method
Application is carried out in accordance with Belzona Know-How System Leaflets SOS-1 & 2.  After removing and replacing "top hat" inspection covers, Belzona 1111 applied to fair off before coating entire tube with Belzona 1341.
Belzona Facts
The application is an annual job that is performed while the ferry is in dry dock. Although most of the Belzona 1341 is intact, by applying an extra coat of Belzona 1341 over the existing Belzona coating the jet tubes are kept in full working service rather than waiting until a major failure.
