Effect of Ship Inherent Controllability on Piloted Performance: The SimulatorExperiment

摘要

The simulator experiment reported here is a component of the USCG WaterwayPerformance, Design and Evaluation Study, and was done for the development of a procedure to predict performance or risk in a waterway from the characteristics of user traffic. A sample of seven commercial ships, ranging in size from a 33,000 deadweight ton (dwt) bulker to a 250,000 dwt tanker, made multiple transits, under similar channel and environmental conditions, controlled by commercial pilots, in a experiment conducted at the simulator at the USCG Academy in New London, Connecticut. A preliminary analysis that found that piloted performance data grouped over all transits for a given ship varied as expected with ship size (displacement), but was not sensitive to controllability indices. A more detailed analysis by individual runs found that performance was sensitive to these indices.
