RO/RO-Causeway Platform Facility Off-Loading Performance in Sea State 3

摘要

The seakeeping model experiments conducted are an integral part of the Naval Sea Systems Command (NAVSEA) program to develop new technology that will enable all U.S. Flag roll-on/roll-off vessels to be safely off-loaded offshore in rough seas (Sea State 3 conditions - 5 ft significant wave height). The offshore off-loading system currently under investigation employs standard Navy causeway sections which would be transported to the off-loading site on ships. A platform capable of supporting the lower end of an off-loading ramp would be assembled by interconnecting several causeway sections and mooring them to the ship. Vehicles would be driven from the ship onto the platform via the ramp. Self-propelled causeway ferries consisting of several other standard sections driven by a powered causeway section would then ferry the equipment from the platform to the beach. The experiment described in this report was conducted in the Maneuvering and Seakeeping Facility at the David Taylor Naval Ship Research and Development Center. In this experiment, motions were measured at several headings and speeds in regular and random waves for two model configurations. Keywords: charts; experimental data; transfer functions.
