Study on the Maneuverability of Barge by Captive Model Test

Abstract

For the tug-barge simulation, captive model test(Horizontal Planar Motion Mechanism) of the barge model is carried out. From the result of HPMM test, a resistance coefficient, maneuvering coefficients of the barge are obtained. A mathmatical model of the barge is validated by turning simulations with different angle of towing line applied a simple towing line model and the tactical diameter compared to sea trial data. As a result, the tactical diameter of the barge is smaller as the angle of towing line is bigger. The tactical diameter from simulations is smaller than that from sea trial data, may be caused by increased displacement of the barge.
