Marine Tug Boat
Cat Tier 3 Power Solutions Deliver Superior
Performance on John Quigg
Caterpillar
Marine Power Systems is pleased to announce Harley
Marine Services is participating in a field follow study of
the Cat® 3500 United States EPA Tier 3 compliant marine
propulsion engines scheduled for completion in May 2012. 2x
Cat 3512C HD engines are installed on the John Quigg, a
4,500 horsepower tractor tugboat positioned in Long Beach,
California. Each 3512C HD engine provides 1678 bkw (2250
bhp) at 1800 rpm. By installing the 3500 Tier
3 engines, the John Quigg will reduce NOx emissions while
operating in the Port of Los Angeles and Long Beach.
Since installation of the engines in late 2011, the
John Quigg's 3512C Tier 3 engines have operated smoothly
without any disruption to service. "We are
happy with the performance thus far, and the partnership
with Caterpillar Marine Power Systems has been superb,"
reported Doug Houghton Harley Marine Services general
manager. "Our local engineering team has
adapted to the new engines and has been happy with the
results."
In January 2012, the legendary Cat 3500C marine
engines entered full production meeting United States EPA
Tier 3 regulations. Cat 3500C Tier 3 compliant offerings
include propulsion, auxiliary and diesel electric
propulsion (DEP) engines. 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 the engines.
The 3512C Tier 3 is a vee-12 cylinder engine with a
170 millimeter bore by 215 millimeter stroke and 58.6 liter
displacement. The 3516C Tier 3 is a vee-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 1,000 and 2,525 bkw designed for
various applications and duty cycles with added design
enhancements to increase durability.
"Harley Marine Service is a respected industry leader
in the tug and salvage market and we're pleased they are
partnering with Caterpillar to deliver more sustainable
solutions to customers," said Grant Hughes Caterpillar
Marine Power Systems sales manager.

transportation company providing quality services along the
