Hull models are generated by BHGI’s engineers and are run at various conditions to predict the performance of the vessel. BHGI uses CFD analysis to estimate ship hull performance in calm waters. This is especially useful when looking to optimize the vessel’s hull form to improve fuel economy. We have used our CFD capabilities to conduct comparative studies of barges, tugs, towboats, and ATB units. From these studies, hull form was able to be optimized to provide vessels with improved flow and resistance characteristics. CFD results include running waterline, resistance, wave train, pressure plots, and a variety of other analyses. BHGI uses these results to determine the best hull for its client’s needs.
