Feasibility Study of Flotation of Sunken Vessels by Injection of Foamed Flotation Material

摘要

Continued laboratory experimentation under pressurized water and a test demonstration at the Experimental Diving Unit have resulted in the conclusion that technically and economically it is feasible to inject foamed flotation materials into sunken vessels to refloat them. A foamed salvage method is estimated to take less than one-tenth the time and cost less than one-half of a conventional salvage operation. Continued experimentation is necessary to fully develop the method and materials of foamed flotation. (Author)
