Buoyant Lift Systems for the Salvage Navy

摘要

Presently the Navy's buoyant lift capability is centered around the 8.4-ton salvage pontoons. Purchased in the mid 60's, these pontoons have been reliable tools, but due to natural deterioration they are reaching the end of their usefulness and must be replaced. Recent technological advancement in materials and buoyant lift systems designs suggest that an increase in operational capability and flexibility can be achieved through lift bags. Modern lift bags are light in weight, easily handled by two persons (up to 10-ton capacity) and require minimal storage space and maintenance. Their advantages make them ideal for shipboard deployment and salvage application. These lift bags are proposed as replacements for the 8.4-ton pontoons. Some questions remain as to the best materials and design for Navy salvage application. The subsequent phases of this project will attempt to answer these questions. It is recommended that commerical bags be tested, evaluated, and if they meet Navy requirements, procured. (Author)
