Caterpillar to Offer 3500C Tier 3 Marine Power Solutions
Starting in January 2012, Caterpillar Marine Power Systems
marine engines will enter full production meeting U.S. EPA Tier 3 regulations.
Cat 3500C Tier 3 compliant offerings will include propulsion, auxiliary and
diesel electric propulsion engines, the company says.
Consequently, Caterpillar says, all Cat 3500C offerings will
not require after treatment modules to meet Tier 3 regulations as a result of
incorporating innovative fuel and air system modifications into the design of
“We’re pleased to offer our customers impacted by the United
States EPA regulations a timely, comprehensive power solution that doesn’t
require after treatment or sacrifice performance,” Bob Hallengren, Caterpillar
Marine Power Systems product and application manager, said in a company press
release. “We’re offering a wide range of power ratings to the market and were
also able to incorporate several new standard features into the design.”
The 3512C Tier 3 is a V-12 cylinder engine with a 170
millimeter bore by 215 millimeter stroke and 58.6 liter displacement. The 3516C
Tier 3 is a V-16 cylinder with a 170 millimeter bore by 215 millimeter stroke
and 78.08 liter displacement. Both engine series include a broad spectrum of
1,600 and 1,800 rpm options with power ratings ranging between 1,341 and 3,386
bhp designed for various applications and duty cycles with added design
enhancements to increase durability.
“We installed the 3516C EPA Tier 3 engines on the Ocean
Titan, a 120-foot Z-drive tug boat and have been very pleased with the powerful
performance delivered by the Tier 3 engines,” noted Bob Shrewsbury, co-owner of
Western Towboats based in Seattle. “It is imperative for our operations to
incorporate sustainable, efficient power solutions into our vessels and we know
we can always rely on Caterpillar for innovative product offerings that help us
get the job done.”
For customers operating in IMO-II regulated waters and
non-EPA regulated territories, the Cat 3500C Tier 2 compliant engines can still
be ordered in 2012. Those customers operating within EPA regulated waters will
be able to order the Tier 3 compliant 3512C and 3516C engines from their local
Cat dealers starting in fourth quarter 2011.
