Notes: While serving as the naval architect and consulting engineer of the EFC, Theodore E. Ferris prepared preliminary plans for three types of fabricated cargo ships (Designs 1022, 1023, and 1025) and four standard types of cargo ships of regular construction, one of 8800 deadweight tons (later Design 1019), one of 7500 dwt (later Design 1026), one of 5500 dwt (later Design 1033, a "Spliced Laker" designed to be cut in two parts for transiting the Welland Canal and then reassembled), and one of 3500 dwt (later Design 1020). The builders would have done the detailed design work and produced the building plans. On 20 October 1917 the EFC concluded its Contract no. 94 with the Hampton Roads Shipbuilding & Dry Dock Co. of Norfolk, Va., for "four steel vessels of the Ferris type, 7300 dwt, 11.5 knots at deep load," (EFC hulls 649-652), with the EFC having an option to order four more. In October 1917 the press reported that the Hampton Roads Shipbuilding & Dry Dock Co. had been incorporated and had secured a site at West Norfolk; in December it reported the contract for the four ships; and in January 1918 it reported the purchase of a 150 acre site. However this contract was cancelled on 2 February 1918 and on 14 February 1918 EFC vice president Charles Piez ordered it abandoned. No other orders were issued for Design 1026 (its plans were never completed) and none were issued for Design 1033. As a result Designs 1026 and 1033 were never built, but an EFC document gives their measurements as 385' oa, 370' pp x 53' x 30'6" and 7300 tons for Design 1026 and 387'3" oa, 373' pp x 43'9" x 28' and 5650 tons for Design 1033. These measurements for Design 1026 almost exactly match those in an article, "Standard Single-Screw Steel Steamship for U.S. Shipping Board's Emergency Fleet," in International Marine Engineering, August 1917, pages 355-7, from which the rest of the details on this page, including the plans, are taken. The plans and specifications for Design 1026, which were issued by the EFC in around July 1917, were for a vessel of the single-screw type with straight stem and elliptical stern, schooner rigged with two steel pole masts. The hull was built on the transverse system with two steel decks and a raised forecastle, long bridge, and a full poop. Six watertight bulkheads divided the hull into seven watertight compartments, four of the bulkheads extended to the upper deck and two to the main deck below it. In addition to the five main cargo hatches the design included four cargo ports, each with a clear opening of about 7'8" x 5'8", fitted on each side of the vessel between the upper and main decks. Each of the four main hatches was served by three wooden booms of 5 tons capacity and hatch no. 2 also had one steel boom of 30 tons capacity. Hatch no. 3, between the bridge and funnel, had two booms of 1.5 tons capacity each. For propulsion the default was one vertical inverted three-cylinder, triple expansion engine with cylinders of 24.5", 41.5" and 72" diameter and a 48" stroke and two single-ended four-furnace oil-fired Scotch boilers delivering steam at 190 psi, although the specifications also allowed the use of a geared turbine of equivalent power and watertube boilers supplying 200 psi steam. Officers and engineers were berthed amidships, the ship's crew in the forecastle, and the crews for the two guns in the poop. Of the six EFC designs for freighters in the 7300-7500 ton range (Designs 1014, 1017, 1022, 1026, 1046, and 1063) this one was the smallest, the next smallest being the 7400-ton Design 1046 at 391.7' oa and 377' pp. Specifications: Design 1026 (Not built): Steel Cargo. Deadweight tons: 7300 designed. Dimensions: 385' length oa, 370' pp x 53' beam mld. x 30' depth mld., 24' draft loaded. Propulsion: 1 screw, 1 triple expansion engine, 2 Scotch boilers, 11.5 kts. Configuration: 3-island, 2 decks, 4 holds, 5 hatches. |
