Splashing into the Ohio River on January 31 at the company's Neville Island shipyard near Pittsburgh, Pa., the 10,100-horsepower vessel will join the fleet of The Valley Line Company, St. Louis, Mo., a subsidiary of Chromalloy American Corporation. Thomas J. Barta, Valley Line president, said the towboat will begin operating early this spring, handling 40-barge tows of approximate- ly 50,000 tons. Principal cargoes will include coal, s'teel, ores and grain. The new boat will operate on the Mississippi River, between St. Louis and New Orleans, La. With the addition of this first-of-its-power vessel, Valley Line's fleet totals 21 towboats and 750 barges. The company is one of the largest operating on the country's rivers and coastal waterways. Powered by three General Motors marine diesel engines—each rated at 3,367 horsepower —the new boat measures 190 by 54 by 12^4 feet. It will 'be driven by three 10-foot-diameter five-bladed stainless steel propellers, housed in Kort nozzles. The vessel has the latest safety and pollution Final construction view of the 10,100-hp towboat which will handle 40-barge tows of approximately 50,000 tons. Cargoes will include coal, steel, ores and grain. control equipment, including inboard fuel bunkers to protect against river contamination in the event of a side puncture. Control features of the towboat will include devices for automatic transfer of generator load; remote-reading instruments and alarms for monitoring engine performance ; and remote controls for fuel bunkering and transfer, and bilge pumping. Propulsion and maneuvering will be com- pletely controlled from the pilothouse, which is also equipped with radar, ship-to-shore tele- phone, depth finder, autopilot with standby steering system, other modern navigational aids, and remote deck winch controls. Pilothouse, quarters and mess facilities will be air-conditioned. The welded steel hull is compartmented into five watertight areas: fore peak ballast tank, fuel bunkers and wing ballast tanks, machinery space, shaft alley and aft void space. Steel superstructure consists of a main deck- house, an upper deckhouse, an electronics space and a pilothouse. The remote-controlled operating equipment will include: Modified VHF radio for use as a mobile telephone; another VHF radio for lock corn- One of three 3,367-hp GM Electro-Motive Division ma- rine diesel engines is lowered into position for the first- of-its-power towboat designed and built by Dravo. 6 Maritime Reporter/Engineering News
