Inland Insights New Towboat Built on Old Hull Stewart & Stevenson Services, Inc., based in Harvey, La., has delivered a towboat, Espiritu Paraguayo, to Asun- cion, Paraguay to Navegacion Paraguaya Americana S.A., a company affiliated with the South American barge line ventures of Allen Mott. This is the third towboat purchased by Mott from Stewart & Stevenson, and the fourth towboat powered by Electro- Motive Division of General Motors (EMD) engines by S&S for Mott and Mott's affiliates. Espiritu Paraguayo was completed using the hull of Senator Eastland, pre- viously owned by Brent Towing Co., Inc., Greenville, Miss., which burned in 1989 on the Arkansas River. After the fire, the vessel was towed to Superior Boat Works, Inc., in Greenville, and the machinery and deck- house was removed and the hull was painted and stored. In 1997, S&S pur- chased the hull, along with new rudders and propeller shafts, as well as the old propellers. S&S commissioned Design Associates, Inc., to do a powering study of the vessel, which concluded it could be rebuilt and repowered as a 5,400 hp towboat. S&S subcontracted with Halter Marine, Inc., to do the detailed design and to repair the hull, then complete the boat in an "all new" condition. The hull was towed to Halter Gulf Repair in New Orleans, and drydocked. Audio gauge readings of the hull revealed the hull was in "like-new" condition. Gridcooler boxes were changed, and some added, and the channel coolers for the genera- tors were lengthened. Sea chests for the special firefighting equipment and watermaker were added. New, larger strut barrels were installed. All new bearings were installed in the rudder and flanking rudder trunks. New bearings were installed in the strut bar- rels and stern tubes, new Johnson Air Seal packing glands were installed and new Cooper split bearings were installed on the intermediate shafts. Additionally, a new pair of Bollinger 102 x 98 in. stainless steel four-blade propellers, with 90 percent developed area ratio was installed. New rudders were installed, as were new Fernstrum gridcoolers, and the hull was sandblast- ed and painted. The hull was refloated and towed to Halter Marine, Inc., in Lockport, La. When the hull arrived, the interior was prepared for some changes and the machinery was installed. A pair of Lufkin Model RHS 3020 reverse-reduc- tion gears, with 3.75:1 ratios were installed, and then a pair of remanufac- July, 1999 tured EMD 16-645EC turbocharged engines to produce 2,720 hp each at 800 rpm. Finally, two Detroit Diesel 8V71N, 115 kW generator sets were installed. After installation of the machinery and major piping, the deckhouses were installed on the hull, and outfitting began. An entirely new steering system was installed, with all new tillers, jockey bars, pins and hydraulic equipment designed by Skipper Hydraulics, Inc., of Harvey, La. fa MACHINE & FABRICATORS,.,.
