AN INVESTIGATION OF THE FACTORS INFLUENCING PILOTED CONTROLLABILITY IN RESTRICTED WATERWAYS

This report describes three experiments performed on the CAORF Ship Simulator to examine pilot controllability of an 80,000 DWT tanker in a channel as a function of channel width, buoy arrangement and spacing, wind, current, visibility, passing traffic, and use of radar. The experiment methodology and results are described. It was found that the optimum buoy spacing is related to channel width, that narrower channel width improves track-keeping, that wind was the most disturbing force affecting shiphandling, and that the combination of fog and passing traffic in an 800-foot channel presents a potentially hazardous situation. It was also found that individual pilots could be distinguished by their different tolerances for off-track distances and different use of rudder.
