PREDICTION OF THE BEHAVIOR AND PROPULSIVE PERFORMANCE OF SHIPS WITH BULBOUS BOW IN WAVES
A bulbous bow designed with regard only to its smooth-water performance may result in ships that behave unfavorably in rough water. Research programs at the Hamburg and Berlin model basins have provided a quantity of design data needed to predict seakeeping performance. By means of frequency response functions obtained from tests in regular waves, the rough-water performance of ships with and without bow bulbs can be compared computationally. A theoretical study on speed loss under service conditions confirms an earlier statement that ships with bulbous bows have almost the same seakeeping qualities as comparable nonbulbous ships up to Beaufort 6; that is, the bulb may be designed with regard to smooth-water performance only. It is prudent, however, to avoid extremely large bulbs.
