Power then is transferred from the torque shaft to the propulsion disconnect quill mounted Wichita ATD- 248 clutch. A Wichita ATD-242 brake for stopping the propeller shaft is located at the forward side of the reduction gear housing. The rotating parts of the brake are connected to an extension of the forward end of the quill pinion, via a splined tooth arrangement. The reduction gears' lube oil system is self-contained ex­ cept for ship's supply of cooling water and necessary electrical connections. The reduction gear and its lube oil system is instrumented so as to qualify for ABS certified automatic, requiring surveillance by only one engineer. The actual connection between the 121-foot by 90- foot catamaran tug and the 588-foot barge is a gather­ ing type wedge bit in the extension from the barge that is tapered. The barge has a molded breadth of 95 feet and an operating draft of 37 feet. Its 18 cargo tanks have a capacity of 13,544,775 gallons of fluid. With gasoline in her tanks, the Challenger's cargo is worth $8.2 million. For a car that averages 16 miles per gallon, the Challenger's cargo of gasoline could provide for 217 million miles of driving, or two and one-third trips to the sun. The unique feature of Catug lies in its design to give it more stability and speed than a conventional tug/barge combination. Although it functions as a tanker ship underway, its construction price was less than for a ship of comparable capacity. LUFKIN is proud to be a part of the team that makes the Seabulk Challenger a new and highly economical mode of transportation for petroleum products.
