Abstract
The author discusses the features of various steamship designs which were considered in the development and final adoption of the construction of the tanker S.S. J. W. Van Dyke. After data on steamship designs had been collected and analyzed an intensive study was made of hull form, propeller design, and power-plant requirements. The author describes the results of model tests conducted at model basins in Hamburg, Germany, and Washington, D. C.; the results of these tests were the deciding factor in selecting the propeller and hull designs. The paper includes a complete description of the steam-generating equipment, electrical equipment, high-pressure piping, controls, and miscellaneous electrical equipment which were finally selected for the ship. The author presents graphically the results of trial runs made with this turbine-electric steamship.
