Notes: In late 1917 Theodore E. Ferris, the EFC's naval architect and consulting engineer, examined and approved designs and specifications by shipbuilders for standardized vessels that included four freighters and two tankers. The tankers were this 7,500 deadweight ton design by the Bethlehem Shipbuilding Corp.'s Harlan Plant at Wilmington, Del. (formerly the Harlan & Hollingsworth Corp.) which was designated Design 1031, and a 10,000-ton design by the Baltimore Dry Docks & Ship Building Co. that was first designated Design 1030 and became Design 1059 after having its lines modified. Both were listed by the EFC as "Standard Tankships" with Design 1031 measuring 405.0' oa, 392.0' pp x 51.0 mld. x 30.2' depth mld. These measurements exactly match those of an earlier single ship, Yard no. 440, George E. Paddleford (392' x 51' x 30.2', with similar machinery), which was launched at Wilmington on 18 April 1916 for the Petroleum Transport Co. and whose plans were probably those submitted to Ferris. Design 1031 was used by two builders, Bethlehem at Wilmington and Terry Shipbuilding at Savannah, Ga., although the Terry ships are on a separate page here because the EFC produced separate plans for them. Three ships (EFC Hulls 1139-1141) were ordered from Bethlehem, Wilmington, on 31 December 1917 and three more (EFC Hulls 1982-1984) followed on 15 May 1918. Specifications: Design 1031 (S.S. Cabrille, EFC Hull 1139): Steel Tanker. Deadweight tons: 7500 designed, 7500 actual. Dimensions: 405' length oa, 392' pp x 51' beam mld. x 30.2' depth mld., 24.25' draft loaded. Propulsion: 1 screw, 1 triple expansion engine, 3 Scotch boilers, 2500 IHP, 11 kts. |
