Robert Allan Ltd. Designs New Fleet of Pusher Tugs & Barges

River system, with an expected delivery in 2017. This shal- low-draft ? eet includes three RApide 4000-Z3 class main- line pusher tugs, one RApide 2600-Z3 class pusher tug, three RApide 2000-Z2 class port-assist pusher tugs, and 64 jumbo hopper barges. During the early phases of design, extensive Computational Fluid Dynamics (CFD) simula- tions were used to optimize the hull shapes to minimize total convoy resistance. In all cases, the z-drives are ? tted in customized tunnels designed to optimize ? ow and propul- sion ef? ciency while reducing draft. In conjunction, logis- tics modeling of the transportation system optimized the selection of vessels for the desired route and analyzed op-
