CONCEPTUAL DESIGN AND PERFORMANCE COMPARISON. TWIN HULL VS. STANDARD BARGE
Much of the tug/barge traffic along the coast of British Columbia transports light-weight loads of high cubic volume. This paper describes a comprehensive investigation by the National Research Council of Canada to examine the suggestion that this type of load could be more efficiently carried using, instead of the conventional wide, flat-bottomed, blunt-ended barges, catamaran-type barges with their twin hulls shaped for lower hydrodynamic resistance. As a result of a large number of tank tests with barge models, it was found that worthwhile improvements in efficiency, enabling a given load to be transported more cheaply at the same speed, or more rapidly for a given cost, could be achieved by the catamaran barge. It is pointed out, however, that the best hull lines and skeg arrangements for specified traffic requirements can only be determined by detailed model tests.
