Caterpillar Marine has launched the Cat C9.3 ACERT Marine platform, a EPA Tier 3 compliant addition to the manufacturer’s commercial market portfolio. The engines and generators are MCS approved commercial solutions available with optional alarm and protection systems supporting all global marine markets. Ratings are available meeting EPA Tier 3, EU/CCNR Stage II and IMOII regulations.
The following is the full range of ratings associated with propulsion, auxiliary and generator sets:
375bhp at 1,800rpm (280bkW)
416bhp at 2,100rpm (310bkW)
476bhp at 2,300rpm (355bkW)
369bhp & 436bhp at 1,800 rpm (275bkW- 325bkW)
292bhp & 362bhp at 1,500 rpm (218bkW- 270bkW)
224ekW- 300ekW at 60Hz
185ekW- 250ekW at 50Hz
The C9.3 ACERT is a six cylinder, 9.3 liter engine derived from the existing platform within the Cat engine family. “Marine customers were looking for a true commercial application with the need for higher load factor capabilities,” Luke Zito, Caterpillar Large Power Systems Division marine value engineer said. "The C9.3 ACERT now strengthens the lower power range of our commercial portfolio, while serving various marine markets."
Caterpillar noted that the engine has been designed with extensive customer input coupled with the company’s integration experience. Gathering and understanding customer feedback has also led to a larger variety of vessel specific solutions offered directly from the factory. “An array of optional attachments are now available because of the feedback received from the field,” Zito stated. “An example of this input is the C1 certified variable speed auxiliary rating that will be able to drive items such as deck cranes, winches and pumps.
