SURVEY OF COLLAPSIBLE PONTOONS.
Abstract
A study was conducted on collapsible salvage pontoons and similar devices that appeared to have potential for ship salvage purposes. The study included a patent search (1850-1966); an examination of the Navy files on collapsible salvage pontoons (1942-1966); a survey of inflatable collapsible devices readily available in the Federal supply system and from manufacturers; a review of reports selected from two Defense Documentation Center report bibliographies; and articles in trade journals and scientific publications. There is a definite place in salvage operations for the modern collapsible salvage pontoons being developed by the Navy. They will supplement, and perhaps eventually replace, the Navy's 80-ton-capacity rigid structural steel pontoons. The collapsible pontoons are durable, can be rolled or folded to minimize storage requirements, and the weight-to-capacity ratio is about 1 to 25 compared to 1 to 2 for the structural steel pontoon.
