Caterpillar Marine Power Systems will unveil its United States EPA Tier 4 power solutions for vessels using engines over 2,000 kW at the 2013 International Workboat Show
The first engine platforms to be rolled out as Tier 4 solutions are two legendary performers in the commercial marine industry: the Cat 3516C marine engine as well as the Cat 280 marine engine. The C280 engine will be available as Tier 4 certified in both the 8 and 12 cylinder configurations.
The Cat 3516C Tier 4 certified engine as well as the Cat C280-8 Tier 4 certified engine and Cat C280-12 Tier 4 certified engine are now all available for customers to order through the global Cat dealer network.
The Cat 3516C Tier 4 certified engine will be available in ratings of 2,240 bkW and 2350 bkW at 1,800 rpm. An auxiliary or diesel electric propulsion solution is available in a 2,250 ekW (2368 bkW) rating. The Cat C280-8 Tier 4 certified marine propulsion engines will be available in ratings of 2,460 bkW and 2,710 bkW at 1,000 rpm with the auxiliary engines and diesel electric propulsion generator set available of 2,185ekW and 2,400ekW at 900 rpm. The Cat C280-12 Tier 4 certified marine propulsion engines will be available in ratings of 3,700bkW and 4,060bkW at 1,000 rpm with the auxiliary engines and diesel electric propulsion generator set available ratings of 3,320kW and 3,640ekW at 900 rpm.
Caterpillar Tier 4 marine technology utilizes aftertreatment combined with a fuel efficiency optimized engine to meet the low NOx regulations. Both the C280 and 3516C Tier 4 certified solutions employ selective catalyst reduction (SCR) technology, which will provide customers with the lowest possible owning and operating costs. The SCR module was designed with the engine room in mind with compact dimensions.
Additionally the inclusion of SCR technology enables customer to leverage shared components as well as a similar engine footprint to EPA Tier 2 and Tier 3 engines. Mark Harrison, Caterpillar engineering manager noted, "We designed our Tier 4 solutions with one goal in mind: to provide the lowest overall owning and operating costs for our customers. We are aware of the impact the regulations have on our customers' bottom line and wanted to ensure our Tier 4 solutions minimized the costs of adopting this new technology."
The Cat 3516C and C280 Tier 4 certified marine power solutions are best suited for customers in the tug and salvage and offshore industries. Cat said additional Tier 4 compliant platforms will be launched in the near future.
