Ships have long been designed to empirical formulate that do not represent realistic conditions for modern naval vessels in extreme sea conditions. as a consequence, ships frequently suffer expensive damage in heavy seas. the objective of the proposed research is to attempt to identify specific… More

The proposed work to establish one or more techniques for offloading containers and break-bulk in all types of weather during a lots mission consists of a review of concepts for ship stabilization, lighter stabilization and load stabilization as individual systems and as members of combined systems.… More

The proposed development involves the characterization, evaluation and modification of a chain -shock absorber utilized commercially. these shock absorbers can be assembled as "links" to form a length of "chain" with the desired shock absorbing characteristics. this chain can either be incorporated… More

The shallow-water and surf-zone mine clearance mission is being addressed by existing U. S. Navy programs. The clearance of manmade obstacles from the surf-zone and beach comprises an equal priority for the amphibious assault mission in littoral warfare. The effectiveness of non-explosive… More

A first-principle mathematical model, designed to analyze parametrically the whole- ship impact of advances in ship technology, is to be developed to a level necessary to demonstrate feasibility as a result of the proposed Phase-I program of work. The model designated PASS for "Parametric Analysis… More

The LCAC Full-Mission Trainer (FMT) is providing a cost-effective tool for training LCAC operators in normal craft operation and casualty mode conditions. However, the FMT was never validated with full-scale LCAC test data. Rather, the feel of the FMT was uning coefficients… More
