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 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: straight channel marking (staggered versus gated buoys), spacing (5/8 versus 1-1/4 nm), channel width (500 versus 800 feet), and intended track (center versus right-hand quarter). Tasks and current effects were varied within the scenario. The findings are presented as the means and standard deviations of crosstrack position of transits under each condition. They are interpreted in terms of their implications both for the design of channel making and for an understanding of the piloting task. A secondary purpose of the experiment was the comparison of performance on the USCG/EA simulator and on CAORF, the Maritime Administration's Computer Aided Operations Research Facility. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: This report is part of the U.S. Coast Guard's Performance of Aids to Navigation (AN) Systems Project. The objective of this project is to provide guidelines for evaluation and design of AN systems in restricted waterways. The major effort has been the evaluation of aid systems under a variety of conditions on a marine simulator developed for the project at Ship Analytics, Inc., North Stonington, Conn. This report describes the implementation task which was designed to experimentally test the draft manual's guidelines for evaluation and design of AN systems in restricted waterways. The Upper Narragansett Bay near Providence, Rhode Island, was the channel in which the draft manual's recommendations were implemented. Data was primarily collected at sea in both the original and modified channel. The at-sea data collection electronically tracked 30,000 dwt tankers inbound in the Upper Narragansett Bay. Data was also collected in the marine simulator developed for the project at Ship Analytics, Inc. Keywords: At-sea data collection; Risk assessment; Risk management; Ship tracking; Buoy placement piloting; Ship bridge simulator; and Short range aids to navigation.

This book was released on 1984 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

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.
