M.A.N.-B&W Turbochargers Reduce Fuel Consumption

—Literature Available During the past year, the Polish engine manufacturer ZGODA tested an NA 34/T M.A.N.-B&W high-efficiency turbocharger on the test bed of a 6 ZL 40 engine. After successful tests, an identical engine from the four-engine plant of the ferry Pomerania was equipped with an NA 34T. Because of excellent results achieved during a 2,000-hour period of operation, the vessel's owner, Polish Baltic Shipping Company, decided to equip the other three engines with M.A.N.-B&W turbochargers.

Polish Baltic reports the following advantages with the new turbochargers: • A reduction in the rate of fuel consumption by 4.5-6.0 grams per kilowatt hour, depending on engine load. For each engine this results in fuel savings of up to $7,000 per year.

• Following the installation of the improved turbocharging system, all engines may now be operated at full load without thermal overload. Consequently, the ferry can be operated at higher speeds during the busy season.

• Technical improvements allow one or two main engines to be shut down sooner than was previously possible when operating at lower speeds during the slow season.
