ANALOG STUDY AND PERFORMANCE OF THE NEW 440-FT FERRIES FOR THE STATE OF WASHINGTON

This paper describes the ac-rectified dc propulsion system designed for the two Washington State ferry vessels, MV Spokane and MV Walla Walla, and reports the results of an analog study conducted as a design tool. Similar data are presented showing the results obtained by recording electrical system performance during builder's trials. These super-class ferries have an 8500-hp, double-armature, direct-current motor installed at each end of the vessel. The power produced by four diesel-generator sets is normally divided 90 percent stern and 10 percent bow or 8500 hp stern, 850 hp bow for a total delivered shaft horsepower of 9350. At the rated speed and capacity, the operation is exceptionally economical, averaging over 85 miles per gallon per passenger for fuel oil.
