As a result of the current energy shortage, the U.S. Navy has been conscientiously examining various means to more efficiently use the available energy sources. Naval ships comsume the equivalent of 78 million barrels of oil each year. During the recent design of a mid-sized, fossil-fueled aircraft carrier (CVV), the Naval Sea Systems Command (NAVSEA) used several new methodologies and techiques in order to design an energy efficient hull form. Model tests were performed with three different hulls, both with and without bulbous bows, and the powering data thus obtained were analyzed by computer on the basis of the ship's speed-time profile and specific fuel consumption data. The three hulls were comparatively evaluated using a rational hull form selection technique which addresses annual fuel costs in addition to traditional naval architectural considerations. It is shown that considerable savings in fuel costs can result from this approach.
