Book Aids to Navigation Principal Findings Report on the Ship Variables Experiment The Effect of Ship Characteristics and Related Variables on Piloting Performance

Download or read book Aids to Navigation Principal Findings Report on the Ship Variables Experiment The Effect of Ship Characteristics and Related Variables on Piloting Performance written by W. R. Bertsche and published by . This book was released on 1981 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: This experiment is one of a series done for the U.S. Coast Guard to quantify the relationship between variables related to aids to navigation and piloting performance in narrow channels and, potentially, safety in such channels. This is one of several experiments restricted to visual piloting, and further to buoys only. It was done on a simulator built for the U.S. Coast Guard at Eclectech Associates in North Stonington, Connecticut. The variables evaluated were: Ship Characteristics: an 80,000 dwt tanker with a rear bridge and an 80-foot height of eye versus a 30,000 dwt tanker with a midship bridge and a 45-foot height of eye; Size and Complexity of Bow Image: larger and smaller bow image for the 30,000 dwt tanker; Speed of transit: 6 knots versus 10 knots; buoy density: a three-buoy turn and short (5/8 nm) spaced, gated buoys versus a one-buoy turn and long (1-1/4 nm) spaced, staggered buoys; and Underkeel clearance: 1 foot versus 600 feet. Only selected combinations of these variables were included as scenarios in the experiment. Tasks and wind and current effects were varied within the scenarios. The findings are presented as the means and standard deviations of crosstrack position of transits under each condition. Observed differences in their inherent controllability parameters to provide a methodology for extrapolating the findings to a variety of ships not included in the experiment.

This book was released on 1981 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: The experiment described here is one of a series done for the U.S. Coast Guard to quantify the relationship between variables related to aids to navigation and piloting performance in narrow channels and, potentially, safety in such channels. This is one of several experiments restricted to visual piloting and was performed on a simulator built for the U.S. Coast Guard at Eclectech Associates in North Stonington, Connecticut. The variable conditions evaluated were: (1) sensitivity ranges (high lateral sensitivity at K is approximately 4.5 or low lateral sensitivity at K approximately 0.5), (2) designated track (with the objective to stay either on the centerline or on the right quarterline), and (3) angle of turn (15-degree or 35-degree noncutoff turn). The constant conditions were a 500-foot channel with two 1.3 nm straight legs joined by a bend. Each straight leg has a range light marking the centerline of the legs and these were the only aids available. The scenarios were run at night with wind and current varying through the transit. The ship was a 30,000 dwt tanker with the bridge 75 feet forward from the center of gravity, and pilots were instructed to keep transit speed at 6 nots. The findings of the experiment are presented as the means and standard deviations of crosstrack position of transits under each condition. These are interpreted in terms of their implications for the design of channel markings. (Author).

Book Aids to Navigation Principal Findings Report The Effect of One Side Channel Markings and Related Conditions on Piloting Performance

This book was released on 1981 with total page 89 pages. Available in PDF, EPUB and Kindle. Book excerpt: This experiment is one of a series done to quantify the relationship between variables related to aids to navigation and piloting performance in narrow channels and, potentially, safety in such channels. This is one of several experiments restricted to visual piloting, and further to buoys only. It was performed on a simulator built for the U.S. Coast Guard. The variable conditions evaluated were: (1) Straight channel markings (buoy configurations were: gated, on one-side inside relative to the turn, on one-side outside relative to the turn, and staggered); (2) Turnmarkings (two-buoy and three-buoy turns); (3) Buoy height above the water (10-foot and 17-foot buoys); (4) Spacing (buoys spaced at 5/8 nm and 1-1/4 nm); and (5) Visibility (at 3/4 nm and 1-1/2 nm). The constant conditions were a 500-foot wide channel with a 35-degree noncutoff turn run during the day with wind and current varying over the scenario. The ship was a 30,000 dwt tanker with the bridge 75 feet forward from the center of gravity, and pilots were instructed to keep transit speed at 6 knots. The findings of the experiment are presented as the means and standard deviations of crosstrack position of transits under each condition. These are interpreted in terms of their implications for the design of channel markings.
