The purpose of the study was to determine whether the modifications made to the vesselís skeg had improved fuel consumption.  The Team was tasked to develop a method to determine whether the modifications made to the T-AGS vessels had an effect on fuel consumption, and if so, did the fuel consumption increase, decrease, or remain the same.  Propulsion fuel consumption was modeled to determine how the skeg modification affects the fuel efficiency of the TAG-S vessels based on vessel speed and sea state.


This study was completed through three tasks.  The figure below provides an overview of the studyís approach.  The light blue box indicates the general efforts to be performed during each task while the darker blue box identifies the results of each task.  The proceeding sections discuss each task in detail.
