Coal-burning Steamship RoRo Ferry: Great Lakes Future Uncertain

A coal-burning steamship ferry of some 400-feet in length, the car and passenger RoRo SS Badger, was amazingly still in commercial operation on Lake Michigan last summer after fifty-nine years, but whether she’ll make her sixtieth anniversary depends upon the US Environmental Protection Agency (EPA). SS Badger: Photo courtesy of Lake Michigan Carferry Service Presently the last coal-feed steamship in operation on the Great Lakes, the  Badger was honoured, amongst many organisations, by the American Society of Mechanical Engineers as a ‘Historic Mechanical Engineering Landmark’. The citation reads:‘The two 3,500-HP steeple compound unaflow steam engines powering SS Badger represent one of the last types of reciprocating marine steam engines. Built by the Skinner Engine Company, most unaflow engines are single expansion. These feature tandem high-and-low-pressure cylinders separated by a common head. The Badger’s four Foster-Wheeler Type D marine boiler... [More]

New Marine Diesel Engines From Cummins EPA Tier 3 Certified

New marine diesel engines by Cummins are now available in its Quantum series, Tier 3 certified by the  US Environmental Protection Agency (EPA). To sell an engine or vehicle within the United States manufacturers must demonstrate compliance with the Clean Air Act and all applicable EPA regulations. Hence Cummins has now upgraded its popular Tier 2 certified QSK19 and QSK60 engines to comply with the more stringent Tier 3 standard. Marine Diesel Engine: Cummins QSK19: Photo credit Cummins A Tier 3 engine requires 50% reduction in particulate matter and a 20% reduction in nitrogen oxides compared to Tier 2 standards, which Cummins achieved through the application of advanced combustion technology without any need for after-treatment of engine exhaust gas emissions.The Tier 3-certified QSK19 and QSK60 feature the same premium base engine hardware and footprint as the existing MCRS product. Furthermore, the lubrication, cooling, air handling, fuel and exhaust systems are the same de... [More]

Reducing particulates on older engines.

As emission requirements become stricter as the years pass, the question arises, what to do with older engines. The EPA Marine Engine Re manufacture Program introduces a law effective March 2008 to force operators of older ship engines to upgrade them to reduce emissions. The rules are rather limited, specifying that the improvement must reduce particulates (PM) by at least 25 per cent, that the engines concerned are commercial (not recreational) applications, manufactured after 1973, over 600kW, cylinder displacement under 30 liters and be a US flagged vessel. The upgrade only becomes compulsory if there is an EPA approved upgrade available and must be carried out at the next scheduled ‘re manufacturing event’ e.g. replacing cylinder liners. Changing many parts to effectively convert an old engine into a new model is usually not economic, nevertheless changing some parts can make a significant reduction in emissions. Although other ways to achieve the same end of reduced emissions are changing fuels, fuel additives or adopting an after treatment system.
