| Abstract |
Navigation in restricted waterways has many challenges for even the most experienced ship handlers. Bank effect is a well known phenomenon that poses ship handling difficulties through the creation of a force and moment which can cause a ship to suddenly deviate from its course. Ship response to bank effect can be very difficult to predict.
Following construction of a new berth pocket and swing basin emanating from the main approach channel at the Port of Townsville, ships began to experience bank effect when passing the new berth. The lack of symmetry in the channel caused ships to slew into the dredged area, at times making ship handling very difficult and dangerous.
A comprehensive study involving full-scale Differential GPS(DGPS) measurements, model-scale testing and theoretical modeling was undertaken to determine the optimum dredging program to reduce the existing bank effect by 50%. The paper concludes with the justification of the option chosen by Townsville Port Authority. |
