Sometimes the least sophisticated vehicle is the hardest to analyze. With respect to resistance, this is definitely the case with barges. In this webinar, we will review three different barge configurations for analysis in NavCad – individual box barges, river barge trains (with pushboat), and integrated tug-barge units (ITB/ATB). The discussion will include review of barge geometries, barge train arrangements and connections, effective “unit” representation for ITB tug and barge, hydrodynamics of box-like vessels, and NavCad’s prediction methods. A brief overview of propulsion considerations will also be presented.
