Abstract

This paper describes the challenge of conserving of a 50-foot long Alclad aluminum Patrol Craft Fast (PCF) for the National Museum of the United States Navy on static display at the Washington Navy Yard. The failed coating was removed using ultra high-pressure (UHP) waterjetting to NACE WJ-2/SSPC-SP standards at pressures between 30,000 and 40,000 psi, a technique that it is non-abrasive to aluminum, non-toxic and environmentally safe. Following waterjetting, corrosion mitigation of the hull and bilge examination, the Swift Boat received a new high performance coating. This paper outlines the challenges, methodology and techniques employed to preserve the original fabric of this large historic vessel and plans to ensure its long-term stability.
