On June 1, 2001, the Billie H picked up a loaded barge from another tug and towed it at nine knots to check the results. They were excellent: Exhaust temperatures were down to well below 900 °F — a reduction of 20 percent. One week later the tug was back at work, towing freight barges between Seattle and Ketchikan. The following year, in March, Lt. Don Miller with the Naval Engineering Support Unit of the Coast Guard in Seattle called ABB with the same problem: The USCG was experiencing high exhaust tempera- tures on the Alco V16 main propulsion engines and the Alco V8 SSDGs on its Polar Class icebreakers. ABB recounted the case of the Billie H and visits to the tug were arranged. Intrigued with the results, the Coast Guard invited ABB to bid replacement turbochargers on a one time trial basis. ABB's offer was accepted and a VTC304 and VTC254 turbocharger were purchased for the V16 and V8 engine, respectively. The units were to be installed by NESU Seattle, with technical assistance provided by ABB. In September 2002 the original turbochargers were removed and the two ABB units were rigged into engine room no.2 on the USCG icebreaker Polar Sea. Within two weeks both units had been installed and testing could commence. Better Data The Coast Guard contracted the U.S. Navy's Fleet Technical Support Center, Atlantic (FTSCLANT) out of Norfolk, Va., to conduct the trials. The tests, which took place at the dock in Seattle, compared main engine I A, fitted with an original Alco turbocharger, with main engine 3A, which had been fitted with the ABB VTC 304 turbocharger. The Polar Sea's No. 2 SSDG with an original factory turbocharger was com- pared with No. 1 SSDG which had had the ABB VTC254 turbocharger fitted. Am Rest-Air Quality, LLC, of Peston, Wash., set up the measuring equipment on the stacks.
