Ashland's New Towboats Being Built By Quality Shipyards To Be Powered By Caterpillar Engines From Whayne Each of the three new twin-screw towboats being built by Quality Shipyards in Houma, La., for the Ashland Petroleum Company will be powered by two Caterpillar 3606 engines delivering a total of 4,200 hp per vessel. "This is the first installation of Caterpillar's 3606 engines utilized in new inland waterways construc- tion," said Jerry Mueller, who is in charge of the engine division at Louisville-based Whayne Supply Company, Caterpillar dealer in Kentucky and southern Indiana. "It represents a real milestone for Ash- land, Quality Shipyards, Whayne, and for Caterpillar, but more impor- tantly it signals what we hope is a turning point for inland river trans- portation." "The CAT 3600 series is the only totally new medium-speed diesel engine in the 2,000-6,000 class hp," said Pete Gibson, Whayne's ma- rine specialist. "These engines are among the most fuel efficient and durable in their power and speed class, 720-1,000 rpm." Delivery of the first Ashland boat is expected in April 1987, followed by the other two by the end of that year. The vessels will replace three veterans of the Ashland fleet. The new vessels will measure 150 feet by 45 feet by 11 feet. Built on a St. Louis Ship design with three decks and pilothouse, each vessel will also include guest quarters. Whayne will also supply two CAT 3306-powered 155-kw generator packages and two Falk MR2440 re- duction gears for each vessel. "The boats will be classed by ABS for inland river service and will operate primarily on the Ohio and the Mississippi Rivers, pushing Ashland tows," said John W. Joeckel, manager of fleet opera- tions for Ashland Petroleum, one of Kentucky's largest employers. Ash- land also operates Great Lakes and oceangoing fleets. Quality Shipyards, Inc. has worked with Caterpillar engines in the past, repowering the Mid-South Towing Company M/V Julia Woods with three Caterpillar 3608 engines earlier this year. Whayne has ordered the new en- gines from Caterpillar's new engine plant at Lafayette, Ind. They will be serviced by Whayne's parts and ser- vice facilities on the Ohio River at Paducah, Evansville, Louisville and Ashland.

These vessels will have the Colt Industries' newly developed diesel engines, the largest engine manufactured in the U.S. Two of these heavy duty 10- cylinder marine diesel engines will provide 32,000 hp to drive the Navy's new fleet oiler vessels which will fuel and supply the fleet at sea. Initial construction of these ships is underway at Avondale Shipyard (New Orleans, La.) and Pennsylva- nia Shipbuilding Company (Ches- ter, Pa.). A total of nine ships out of a planned fleet of 20 are under con- struction at these two shipyards. WABCO, a division of American Standard Inc., will provide three shipsets of electro/pneumatic en- gine propulsion controls to Penn Ship and two sets to Avondale for five of these ships. Each shipset of WABCO controls consists of: two engine control pan- els; two clutch control panels; two engine slow turning panels; and two engine turbo water-wash panels. This equipment will be manufac- tured in Lexington, Ky., under con- tract from Colt Industries and deliv- ered directly to the respective ship- yards.
