Abstract
Over the years, the naval industry has been the most used method to transport goods and materials around the globe. The large capability of carrying cargo as well as its low cost when compared to other transport methods are some of the reasons that makes the naval industry to be the most competitive one. Due to its importance for the global economy, constant research has been developed in order to, each time more, increase the vessels size and consequently augment their load capacity. Since it is one of the most relevant safety criteria of operation, maneuverability performance became an important factor in the design and development process of the increasingly larger vessels. Such performance depends on several factors, such as the vessel's drift angle and its rudder angle. This paper seeks to determine those angles in a steady state scenario through computational procedures in order to analyze their behavior when subjected to known environmental conditions. Moreover, it seeks to inspect the effect on both angles caused by the addition of an escort tug.
