Propulsion Updates Earlier this year, ABB Turbo Systems of Baden, Switzerland started deliv-ering the latest new product from its well-regarded TPL turbocharger fam-ily, the TPL..-B turbocharger. The TPL..-B turbocharger is designed for two-stroke diesel engines as a robust and reliable platform for engine applications ranging from 5,000 to 25,000 kW per turbocharger. The unit is designed for simplicity as much as technical excellence, and the modular design boasts fewer parts than any generation before it, a trait which is designed to equal less and easier service and maintenance, as well as lower life-cycle costs. This concept is plainly evident in the fact that ABB's special TPL inboard plain bearings are designed for 35,000 operation hours, effectively doubling the lifetime of turbocharger bearings. In addition to the new bearing design, the TPL series of turbochargers have no water cooling, and feature inte-grated turbine and compressor clean-ing devices, all factors devised to minimize downtime. As is the hall-mark of all ABB products, however, service and support are available around the world, 24-hours per day, in the event of a product breakdown. Since the market introduction, 70 units have been sold in the past six months, equaling supercharging of a total engine power of nearly 1.4 mil-lion hp. Circle 24 on Reader Service Card #4 unit was installed on the cooling water pumps suction line of each of the vessel's EMD engines. In July of 1999, after 80 months of operation aboard Gulf Fleet 61, the cWc conditioners and several cooling water pipes were removed, and all inspected piping was free of scale, the water sam-ples clear and of a neutral pH level. The cWc cooling water conditioner works because, when circulating cooling water flows through the unit, water mol-ecules and minerals in the water become polarized and realign, staying in suspen-sion and thus not sticking to surfaces. The charged particles in passing make contact with mineral deposits that also become polarized, and are lifted from surfaces and are carried in the cooling water unit flushed from the system.
