IMPACT REDUCTION METHOD FOR SIDE LAUNCHING PONTOON STRUCTURES - INFLATABLE CUSHION

Abstract

When pontoon structures are side-launched from LST's, the high impacts cause damage to the structures that results in excessive maintenance and replacement costs. An expendable fibre board cushion was previously designed; procedures for assembling and attaching it were developed. Impacts and apparent damage to the pontoon structure were reduced to acceptable levels with the fibre board cushions. For reasons of economy the investigation was continued into the use of reusable inflatable cushion materials. These were found to be less effective, and are also undesirable and impractical for reasons of handling. Use of the inflatable units for impact reduction is not recommended.
