Ν Shell Chemical's Integrated Tow

Four barges and a pusher-type river boat Have arrived at a Chicago termi­nal o n the first leg of a 22-day round trip. In the first integrated petro­chemical tow o n the Mississippi Water­ways System, says Shell Chemical, the barges carried glycerol, hexylene gly­col, and other products from the com­pany's Houston plant. Three of the Dravo-built barges have nickel-lined steel compartments like the one on the left, a design which permits marine shipment for chemicals which usually travel in specially lined tank cars. The tow r>oat, built by St. Louis Shipbuild­ing & Steel, has two diesel engines, a retractable pilot house for clearing low bridges, and is equipped to steam heat the glycerol compartments
