ON THE ADDED RESISTANCE AND SPEED LOSS IN LOW FORWARD SPEED RANGE

The added resistance in regular head waves of a very large bulk carrier at low forward speed is calculated using a three-dimensional source technique. The numerical results are compared with measured data and also with the value calculated using slender ship theory. The added resistance predicted by the three dimensional source technique is in better agreement with the measured data than is that calculated using the slender ship theory. Using the data on added resistance in regular waves, ship speed in a seaway is also evaluated. For regular moderate seas, the speeds derived using slender ship theory agree well with those based on measured added resistance. For rough seas, however, the speed loss estimated using slender ship theory is too high to use, while that using the three dimensional source technique is acceptable.
