BARGE TRAINS IN A COASTAL SEAWAY PART 3 DIRECTIONAL STABILITY AND CONTROL

Results are given of rotating arm model tests in still water (for one to three line ahead push barge tows) to obtain hydrodynamic data on yaw moment, lateral force, drag and lateral bending moment at the barge tow connections during maneuvering. Dynamic course stability predictions determined from the test results show the turning ability of push tow barge trains is less than that of ordinary ships because of the high degree of stability and relatively less control force. The effect of bow thruster units on push tow controllability is shown. Large lateral bending moments are predicted for push barge trains during tight turns. Computer simulations for pull tow barges, in still water, indicate directional stability can be achieved by use of activated rudders without excessive drag.
