BY CHAD ELMORE
Cummins has launched a new generator set for marine appli- cations that is also among the
first in a line of new products coming out
of the Commercial Marine and Offshore
Oil and Gas Center of Excellence in
Houston. Engineered specifically for
marine applications, the new Cummins
QSM11-CP marine generator sets are
available in ratings of 300 kW at 1800
rpm and 60 Hz or 250 k W at 1500 rpm
and 50 Hz, and are suitable for prime or
auxiliary power service.
“The launch of the QSM11-CP
allows us to fill a gap in the 200 to
300 kWe range while meeting the
latest emissions requirements for
marine equipment,” said Donald Ho,

marine-grade alternator. The 12-wire,
three-phase alternator provides a
broad range of reconnectable outputs, the company said, and carries
an IP23 enclosure rating.
In addition to the engine and alternator, nearly all of the major components of Cummins C Power gen-sets are designed and manufactured
by divisions of Cummins, which the
company said ensures all systems
operate in harmony.
The engine’s Cummins Celect fuel
system is designed to offer precise
fuel injection for reduced smoke and
responsive performance, said the
company. The standard capacity of
the lubrication system is 34 L, and
spin-on Cummins Filtration filters can
be mounted remotely for flexibility in
installation. Skid-mounted duplex oil
filters are also available.

The QSM11-CP gen-set was designed and are assembled at the
Houston facility, which serves as
one of two global marine Centers of
Excellence, with the other in Singapore.
“The opening of the Commercial
Marine Center of Excellence enables
us to expand this product line beyond
the current offering by consolidat-
ing design, testing, integration and
support resources that exist across
the Cummins factory and distribution
channel,” said Jenny Bush, general
