Aids to Navigation SRA Supplemental Experiment Principal Findings: Performance of Short Range Aids under Varied Shiphandling Conditions.

摘要

This report describes an experiment planned as a component of the United States Coast Guard's Performance of Aids to Navigation Systems Project, Addendum. The purpose of this experiment was to supplement the visual experimental data that were used to develop the SRA/RA manual and to further extend it. The variables evaluated in this experiment include: ship size - a 30,000, 52,000 or 80,000 dwt vessel; ship speed - approximately 6 or 10 knots; channel width - 500 or 800 feet; buoy arrangement - 1, 2, or 3 buoys marking the turn, and gated buoys spaced at 5/8 or 1-1/4 nm intervals or staggered buoys spaced at 1-1/4 nm intervals along one side marking the straight legs; lightning conditions - day or night; and design environmental conditions of wind, current, and underkeel clearance. The data evaluated in this report will be used to modify the Draft SRA/RA Systems Manual for Restricted Waterways.
