existing MaK 7 M 43 C on the 16,000 dwt chemical tanker Fure West to LEE standard during a scheduled vessel stopover in the port of Rostock, Germany. During a four-day stopover in October 2007, a service crew from Pon Power A/S, Caterpillar’s MaK dealer for Scandinavia, supported by engineers from Caterpillar Motoren facilities in Kiel and Rostock, completed retrofitting, including Marine Classification Society (MCS) approval. Similar to the retrofitting of Fure West, all existing MaK M 20 C, M 25 C, M 32 C and M 43 C series marine engines afloat can be converted to MaK LEE standard—at about only 15-25% of the cost of a new IMO II-compliant engine. Building upon proven technology residing inside the engine, MaK LEE bears many advantages for vessel owners and operators. Following the retrofit, the Fure West is the world’s first known IMO II-compliant medium-speed HFO-fueled marine engine afloat. Commenting on the results of the Fure West’s sea trial, Dr. Udo SchlemmerKelling, manager of Research at Cater- pillar Motoren in Kiel, said: “With NOx emissions down to 8.3 g/kWh, or 36% below current IMO regulations, and soot emissions reduced to less than 0.5 FSN (Filter Smoke Number) over the whole load range, our MaK LEE technology clearly deserves the name Low Emission Engine.” In the next months, more MaK Low Emission Engines will be delivered to customers. Among them are two ship sets comprising 3x 12 M 43 C and 3x 16 M 43 C each for Norwegian Cruise Line’s “F3” newbuildings under construction at Aker Yards in France. These engines will supply 950 kW per cylinder, enabling DNV Clean Design compliance and a fuel consumption of 176 g/kWh—which is actually one gram under the 1,000 kW per cylinder IMO I rating of the M 43 C. By 2010, about half of all MaK M 20 C, M 25 C, M 32 C and M 43 C marine engines built will be of LEE design. Once IMO II emission regulations take effect, every medium-speed marine engine produced at Caterpillar Motoren facilities in Kiel, Rostock or Guangdong, China will be a MaK Low Emission Engine. ML ABB extends compact turbocharger family Turbochargers are a critical component in allowing engine builders to generate high power, while reducing fuel consumption and emissions. ABB Turbocharging, Baden, Switzerland, has just extended its successful TPS F family turbochargers with the addition of the TPS44-F for small mediumand high-speed engines rated below 500 kW. Beginning with the market introduction of the TPS F33 series with compressor pressure ratios of up to 4.7 in 2000, ABB Turbocharging has added, at two-year intervals, the TPS F32 and TPS F31 series for full load pressure ratios of up to 5.0 and 5.2, respectively. The compressors developed for the TPS F family also allow a 15% better flow rate than the TPS E turbocharger for a given frame size. To date, ABB has offered four TPS F frame sizes for small mediumspeed diesel engines, large high-speed diesel engines and gas engines in the power range of 500 to 3,300 kW. With the launch of the TPS44-F, ABB has extended the application area of the TPS F family to the lowest rated HFO burning mediumspeed engines and meets the specific requirements of smaller high-speed diesel and gas engines now coming onto the market. Three radial compressor stages support engine operators’ efforts to reduce emissions and fuel consumption while providing the high power necessary to compete successfully in the marketplace. The first of these new smallest turbochargers to be launched are the TPS44F31 and TPS44-F32, offering users full-load pressure ratios of up to 4.8. The TPS44-F33 version with enlarged volume flow is scheduled for release later this year. www.marinelog.com MARH 2008 MARINE LOG 25 http://www.jokell.com http://www.jokell.com http://www.marinelog.com
