RESTRICTED WATERWAYS EXPERIMENT 111A, DATA ANALYSIS AND FINDINGS
The objective of Experiment 111A was to investigate effect of channel design, ship maneuverability, and aids to navigation configuration of the pilots' ability to navigate a narrow (500 ft wide) channel 5 NM long containing 3 turns. The experiment consisted of transits of the simulated channel using the CAORF bridge simulator adjusted for an 80,000 dwt tanker. The experimental design reflected presence or absence of traffic, full or half normal rudder area and aid to navigation conditions including two buoy configurations, ranges, and precise navigator. Ship position and attitude data and ship control orders were collected during each transit. Conclusions included evaluation of success in transiting the channel, variance in cross track position effect of traffic ships, and an evaluation of ship control orders. Conclusions from static position estimation trials include evaluation of position estimation accuracy and statistics on the accuracy of bearing estimation related to actual bearing angle. The report also deals with the ability of CAORF to simulate navigation ranges.
