Newscopy: "PACECO BUILDS POWERFUL DREDGE - One of the most powerful dredges in the world is being built by Pacific Engineering Company of Alameda, California, according to D.C. Faber, Marine Manager of the firm. Built for Utah Construction Company, San Francisco, the new dredge is designed to move more than 40,000 cu. yards per day. Its powerplant, a DeLaval Turbo Generator, has a 12,650 KW output, enough power to supply a village of over 5,000 population. Over-all dimensions of the dredge measure 208 feet long by 50 feet wide by 14 feet deep. The dredge pump has a 36" suction and a 30" discharge, powered by an 8,000 H.P. Westinghouse main pump motor, the largest ever built in the West. A PACECO 25-ton jib crane will be mounted on top of the accommodation area to service the main pump. Operation in depths to 52 feet is accomplished with a 325-ton digging ladder, which measures 78 feet long. A 9-foot diameter cutter head weighing 18 tons will be powered by a 2,000 H.P. Westinghouse Electric motor, driving through a cutter drive reducer, one of the largest made by the Western Gear Corporation. The cutter drive itself measures 13 feet high by 11 feet wide by 8 feet long and weighs 57 tons. The new dredge will have two spuds weighing 45 tons each. The spuds are 95 feet long and 42" in diameter, and are raised or lowered by a PACECO spud winch powered with a 150 H.P. motor."
