Title: Process for refurbishing metal buoys

Abstract: A procedure for refurbishing hollow metal buoys that have been surveyed out of service. The buoy repair method involves removing a metal section, filling the buoy interior with polyurethane foam, welding back the removed metal section and coating the metal exterior with fiber glass-resin composition. Buoys repaired in this manner are essentially maintenance free.
