Abstract:

The feasibility of using urethane foam floats as replacements for conventional steel dredge pipe floats was investigated. Material and design requirements were determined, and two 18-scale models were fabricated. It was concluded that a full- scale model of a float of this design could be fabricated by personnel at a remote location with limited knowledge of materials and equipment for foaming operations but that only in-service testing of a prototype model fabricated in the field would indicate whether it would be able to satisfactorily withstand the severe conditions encountered in actual use.
