RESISTANCE AND POWERING PREDICTIONS FOR A U.S. MARITIME ADMINISTRATION "SECURITY" CLASS MOBILIZATION SHIP (MARAD DESIGN C7-S-M134A), PHASE III

A design program was conducted by HYDRONAUTICS, Incorporated for the United States Maritime Administration to study the resistance and propulsion characteristics of a 712.9 foot "Security" Class Mobilization Ship. To accomplish this, DTNSRDC Model 5369 was lengthened and a new scale ratio assigned. Model tests were conducted that included bare hull EHP, appended EHP and SHP (at four load conditions), a wake survey, rudder stall examination and flow visualization. All model data were expanded to ship scale and presented. A comparison of performance to other hulls was made. Resistance characteristics for a jumboized version of the base hull form were predicted utilizing the results from the model tests. In addition, lines and offsets for the base hull form were prepared utilizing the U.S. Navy computer program HULDEF.
