PROTOTYPE INFLATABLE CAUSEWAY
Abstract
Utilization of an inflatable-type causeway that could be multi-tiered on an LST, or in the well deck of an LSD, is considered to offer a marked logistics advantage over the present type of causeways. A prototype section of such a causeway was designed and fabricated under contract and evaluated by the Laboratory. The causeway section is a steel-decked beam-and-girder framing (analogous to an inverted muffin tin) supported on inflatable pontoon cells restrained in the cavities. Air inflation is achieved by a source external to the system; a limited auxiliary air supply is housed internally for emergency use. Evaluation results indicate that the inflatable system is feasible, but that the prototype unit is too complex for military operations. Retention of the flotation system is advocated, with a recommended redesign of the superstructure. (Author)
