摘要：	This project went through the typical procedures associated with developing the structural requirements/impacts for a Sealift conversion vessel: (1) Identify the payload requirements and a representative military vehicle payload for the Sealift vessel, (2) Determine the candidate vessels available for the conversion and make a final choice for the conversion study, (3) Develop a preliminary arrangement of the vehicle loadout, i.e., arrange the payload to ensure the selected ship can accommodate the vehicles, (4) Determine the structural loads, global, local and vehicle related, to accommodate the conversion, (5) Determine the structural modifications required to accommodate the new loads and (6) Develop the cost estimates to accommodate the structural modifications, including the addition of vehicle tie downs. The essence of this project was comparison of the structural requirements and resulting modifications from application of the ABS High Speed Naval Craft criteria and the DNV High Speed, Light Craft and Naval Surface Craft criteria. Comprehensive comparison of the global loads, secondary slam loads and vehicle deck loads is developed in the report along with the structural requirements to resist these loads. The report also presents a summary of the finite element analysis work that was developed to investigate the impact of the military payload on the vehicle deck structure. This was of particular interest because the nominal tire footprints for many vehicles are significantly greater than the stiffener spacing, which violates typical assumptions for the design of plate structure subjected to wheel loads.
