Summary of a Full Scale Maneuvering Trial on the USNS Observation Island (T-AGM23)

摘要

The U.S. Coast Guard has undertaken a program to improve their capability for theprediction of full scale ship maneuvering performance. Model Scale experiments have been conducted to provide the necessary hydrodynamic coefficients to the maneuvering performance computer models. Full scale trials were needed to provide validation of the computer predictions. The Carderock Division, Naval Surface Warfare Center (CARDEROCKDIV) was tasked to conduct maneuvering trials on the USNS Observation Island (T-AGM 23). The trial was performed in March 1991 during a shake down cruise from Portland, Oregon to Honolulu, Hawaii. Open ocean position tracking was provided by GPS signals recorded by the ship's computer systems. The position data was then correlated in time with the data collected by CARDEROCKDIV computers.
