Maneuvering Performance of the T-ATF 166 Class Fleet Ocean Tug as Represented by the USNS NAVAJO (T-ATF 169) .

Abstract

This report presents the results of a maneuvering trial conducted on the USNS NAVAJO (T-ATF 169) which represents the T-ATF 166 Class fleet ocean tug. The ahead turning and maneuvering, astern maneuvering, and docking characteristics of the ship were investigated in calm environmental conditions. Steering with the bow thruster provides the best means of achieving good coursekeeping and maneuverability during astern operations at any speed, while maneuvering ahead with the rudders should present no problems. The turning performance of the ship should be the same in either left or right turns. The docking performance of the ship should be excellent with or without the bow thruster in calm environmental conditions. (Author)
