Laker repower earns Clean Diesel award
Repowering efforts by the Interlake Steamship Company have brought it the Midwest Clean Diesel Initiative (MCDI) Leadership Award. Interlake President Mark W. Barker accepted the award at a ceremony in Chicago last month..
Interlake Steamship received the award "for demonstrating outstanding leadership by making significant measurable improvements in air quality through the development and implementation of clean diesel actions."
During the 2009-2010 winter, Interlake repowered the main propulsion engines of MV Paul R. Tregurtha, the largest bulk carrier on the Great Lakes, with a per trip capacity of 70,000 tons. The new engines and energy efficiency improvements will significantly reduce the ship's emissions of nitrogen oxides, particulate matter, and carbon dioxide.
The Tregurtha's two original 16-cylinder Pielstick diesels were replaced with two (2) medium-speed, 6-cylinder MAK model 6M43C diesel engines, each producing 6000 bkW, or 8040 bhp, for a total installed horsepower of 16,080 bhp. The ship returned to service in April 2010.
"We are appreciative of this recognition of our efforts to repower and re-engine our fleet. These projects, of which the Tregurtha repowering was the third, reduce our fleet's emissions and increase our fleet's reliability so that we can maintain dependable service for our customers," said Mr. Barker. "We are pleased that organizations such as MCDI are taking note of the many ongoing efforts by Great Lakes vessel operators to reduce emissions."
Formed in October 2007, the Midwest Clean Diesel Initiative is a collaboration of federal, state and local agencies, along with communities, non-profit organizations and private companies working together to reduce diesel emissions in US EPA Region 5. It assists in voluntary efforts to reduce emissions from existing diesel engines that are not covered by US EPA's stringent standards for cleaner fuels and new, cleaner engines. MCDI estimates that more than 3 million diesel engines in the Midwest would benefit from use of diesel retrofit technologies, repowers, replacement, cleaner fuels, idle-reduction and other clean-diesel strategies. The MCDI Leadership Group says that the public-private partnership already has affected 985,000 of those engines.
