TWIN STERN SHIP FOR ENERGY SAVING
Stern form is being studied in China and elsewhere to determine its potential contribution to the improvement of efficiency and the conservation of energy. In rapid succession, the twin stern ship, twin skeg ship, asymmetric stern, bulb stern and other variations have been developed. This article deals specifically with the twin stern ship, which consists of two demi-sterns at left and right and one central tunnel of the longitudinal stream type. It was first employed in China for river vessels designed by the Changjiang Ship Design Institute. It is shown how both model tests and full scale tests have demonstrated that in comparison with previous designs, the twin stern results in a significant decrease in resistance and a significant increase in propulsive efficiency.
