FIELD TESTING OF PLASTIC MOORING BUOYS. PART II. MODIFICATION AND INITIAL EXPOSURE OF MODIFIED BUOYS.

Abstract

Two experimental plastic mooring buoys, one with a hand lay-up and the other with a spray-up fiberglass-reinforced outer shell, were taken ashore after five months service to the fleet and modified with a heavier fendering system. Laboratory tests of the exterior shells indicated that moisture penetration of the hand lay-up shell below but not above the water line had reduced the strength of the shell in this area. The spray-up shell was equally strong above and below the water line and somewhat below the reduced strength of the hand lay-up shell below the water line. The buoys were readily patched and both were returned for an additional five months of in-service testing.
