For Harley Marine Services, 麻豆传媒映画榞reen麻豆传媒映画� has always been the way to go. So it麻豆传媒映画檚 no surprise that this marine transportation company headquartered in Seattle, Washington, was the first to select a Caterpillar Marine engine solution that meets US Environmental Protection Agency (EPA) Tier 4 Final emissions standards.

麻豆传媒映画淭hey have a reputation for being very sustainable and forward-looking,麻豆传媒映画� said Brent Nelson, a Caterpillar Marine Territory Sales Manager who works closely with Harley Marine. 麻豆传媒映画淭hey want to run a clean, green fleet, and they麻豆传媒映画檙e setting a precedent by being the first to power a vessel with these engines.麻豆传媒映画�

Recognised in the maritime industry for leading the way in environmental stewardship, commitment and initiative, Harley Marine has received numerous national and regional environmental awards, as well as adherence to the ISO 14001 environmental standard since 2008. The company also uses an environmental management system across all its operational areas.

When Harley Marine decided to build a new line haul boat, the Earl W. Redd, for towing up and down the US Pacific Coast, the company wanted a proven power platform that would address the changing emissions requirements. Over the years, Harley Marine had successfully operated numerous line haul tugs powered by Cat 3500 Tier 1 and Tier 2 propulsion engines. Cat dealer Peterson Power suggested two 3516E engines 麻豆传媒映画攁 flexible power solution that addressed both Harley Marine麻豆传媒映画檚 need for power and the upcoming Tier 4 regulations.

To meet the more stringent Tier 4 Final emissions standards coming in 2016, each of the two continuous duty 3516E engines麻豆传媒映画攊ndividually rated with a 10% horsepower increase of 2682 hp at 1600 rpm麻豆传媒映画攊s paired with a selective catalytic reduction (SCR) aftertreatment system. SCR uses a urea-based solution to reduce the oxides of nitrogen (NOx) contained in diesel exhaust down to nitrogen and water vapor. Just as important, it does so efficiently.

麻豆传媒映画淗arley Marine should save over US$1 million across a 15-year lifecycle on total fluid consumption (diesel plus DEF) costs for this new build compared to an equivalent Tier 2 powered vessel. They are able to deliver an increased level of performance due to the higher power rating with increased efficiency,麻豆传媒映画� said Ryan Darnell of Caterpillar麻豆传媒映画檚 Large Power Systems division. 麻豆传媒映画淭hat麻豆传媒映画檚 a direct result of engine fuel efficiency improvements that our SCR technology allows us to make by reducing NOx downstream of the engine combustion process.麻豆传媒映画�

While that was a big reason Harley Marine chose Caterpillar for the Tier 4 Final engine solution, there were plenty of others as well. The company has a long-standing relationship with Caterpillar Marine, including parts and service support from dealers across the United States. In addition, Cat Financial has provided construction and ownership financing for multiple Harley Marine vessels麻豆传媒映画攊ncluding the Earl W. Redd.

For this particular vessel, that includes not just Harley Marine, but also Diversified Marine, Peterson Power, the naval architect and Cat engineers back at the factory. Currently, everything麻豆传媒映画檚 ready for the Cat engines to be delivered to the shipyard in April 2016, with vessel construction complete in October.
