Abstract:

This paper describes the use of a maneuvering simulation in the evaluation of a vessels 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 vessels 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
