Abstract : This paper describes the use of a maneuvering simulation in the evaluation of a vessel's performance during the design stage. The specific case investigated is the new U.S. Navy Salvage Ship ARS-50. The objective of the simulation program was to verify the acceptability of the vessel's maneuvering performance in a wide range of missions. The Ship Maneuvering Simulator at Hydronautics, Incorporated was used; this simulator has relatively simple equipment and displays, coupled to very complete mathematical models. Required ship missions were reviewed, and a group of representative scenarios was developed for evaluation purposes. These included open-water maneuvers, maneuvers around docks and piers, approach and station-keeping on a stranded vessel in shallow water, approach to a drifting vessel and towing of a disabled vessel. The simulations were carried out by experienced Naval Officers with service on ARS-Class vessels and knowledge of the maneuvering and performance requirements of such vessels. The Officers evaluated the performance of the ARS-50 on its ability to carry out the required missions and its performance relative to existing vessels. The maneuvering performance of the ARS-50 was found to be acceptable and recommendations were made relative to some modification of the ship control system. (Author)
