Double-Skin Fuel Barge Delivered By Riverway Yard

Riverway Shipyard Company, Grafton, 111., recently completed construction of a new double-skin, raked tank barge for Waterways Winona, Inc. of Winona, Minn. It will be used as a midstreaming fuel barge for service in Winona. The double-skin raked barge measures 130 feet by 30 feet by 9% feet. The hull is %-inch plate and has 5/16- inch bulkheads. The headlog and corners are %-inch plate. Continuous %-inch rub-bars are located top and bottom on both sides.

The corners have %-inch corner wrapper plates.

The barge has four fuel oil tanks and three dirty oil tanks built in the hull. Located on the deck are two lube oil tanks and two potable water tanks. Fuel oil capacity is 136,212 gallons; dirty oil capacity is 11,018 gallons; lube oil capacity is 3,000 gallons; and potable water capacity is 20,000 gallons.

The fuel oil is unloaded by way of a Byron- Jackson deep well pump at the rate of 500 gallons per minute powered by a GM Detroit Diesel 4-71 engine. The total off-loading time is approximately 4y2 hours. A dirty oil/water separator designed by National Marine Service processes dirty oil at 10 gallons per minute.

Three dirty oil tanks in the bow rake allow processing of dirty oil while the barge is in operation.

Two lube oil pumps, one potable water pump as well as the towing lights and dirty oil/water separator are electrically operated from power received from the towboat pushing the barge.

The barge is certified by the United States Coast Guard for the carriage of Grade "D" products and below. Riverway Shipyard Company is a wholly owned division of Riverway Towing Company, Minneapolis, Minn.

The shipyard is concerned primarily with marine repairs and the design, engineering and construction of deck barges, liquid tank barges, drydocks, barge covers, and towboats.
