Plastic Mooring Buoys-Design and Cost Criteria.

Abstract

Two buoys of FRP/polyester resin shell were fabricated by a hand lay-up and by a spray- p technique. The two plastic mooring buoys have provided goodservice as part of moorings for the Fleet in San Diego Bay for a period of5 years; the hand lay-up shell buoy is in appreciably better conditionthan the spray-up shell buoy. A third plastic buoy was fabricated with animproved design and was placed in service in Pearl Harbor; after 2 years,the buoy is in excellent condition. A cost analysis indicates thepracticality of using plastic rather than steel buoys as components ofFleet moorings. An annual savings of about $6,150 per Class BB mooringcan be achieved using a plastic buoy in conjunction with cathodicallyprotected ground tackle. A PURCHASE SPECIFICATION FOR A PLASTIC MOORINGBUOY IS INCLUDED FOR USE BY Naval field activities. (Author, modified-PL)
