POWER PREDICTION METHOD FOR HIGH BLOCK COEFFICIENT SHIPS WITH TRANSOM STERN

A method of predicting the resistance of high block coefficient ships with transom stern is proposed on the basis of the base drag concept. The model tests to evaluate their base drag were carried out in Nagasaki Experimental Tank. It is shown that the base drag of tanker models could be treated in a manner similar to that of three-dimensional bodies such as missiles and projectiles. The results of power prediction which takes the base drag of transom stern into account show some amount of speed reduction from those obtained by the ordinary method. The speed reduction will become significant when the area ratio of transom to midship section becomes larger.
