U.S. for power plants with the reliability
and flexibility to meet peak power
requirements. An example is a new
peaking duty power plant in Emporia,
Kansas, U.S.A., that Westar Energy is
building, in the wake of record-setting
peak power demands in Kansas last
summer. GE will supply four LM6000
aeroderivative gas turbines and three
Frame 7FA gas turbines for the project.
Plant Upgrades
During 2006, GE completed seven
gas turbine uprates at the Seoinchon
combined-cycle power plant in Inchon
City, Korea. An earlier upgrade on the
first of eight units at the plant led to significantly improved performance, and
paved the way for the upgrade of the
other seven gas turbines.
The project enabled the power plant,
owned by Korea Western Power Co. Ltd.,
to increase its total output by 180 MW.
One of the largest gas turbine uprate contracts ever awarded to GE, the project
demonstrates how innovative technology
and world-class service execution can
boost power plant performance.
Under an agreement with the Eurofo
International Group, a Chinese company, GE is modifying the combustion and
fuel systems of two Frame 6B gas turbines, enabling the machines to burn
purified coke oven gas (COG) for power
generation.
The two Frame 6B machines have
been operating on heavy fuel at a power
plant in Dalian, Liaoning Province,
China. Following the GE modifications,
the two units will be installed at a new
Eurofo combined-cycle plant in Shanxi
Province. This project illustrates how
gas turbine solutions can help cogeneration plants and steel mills improve
efficiencies, while reducing energy costs
and environmental impacts. a

Gas Turbine Development
GE Marine continues as a leading
provider of marine aeroderivative gas
turbines, showcasing its engines in several unique commercial and military
applications.
In the past year, GE completed a
major milestone in the three-year
marine development and type-testing
program for the LM2500+G4 — the
newest addition to its LM aeroderivative
product line and the fourth generation
of GE’s LM2500 technology. The testing
program included a high-power
demonstration to 110% of rated power,
and a 500-hour endurance test at simulated rating point conditions is under
way. GE is seeking simultaneous marine
type approval for the LM2500+G4 with
Bureau Veritas, Registro Italiano Navale
and the American Bureau of Shipping.
The launch marine application for the
LM2500+G4 will be for the joint French
and Italian Navy Frigate European
Multi-Mission (FREMM) program.
Military Applications
In its first military marine application, GE’s LM2500+ powers the U.S.
Navy’s Makin Island (LHD 8) amphibious assault ship. The Makin Island,
christened in August 2006, will be
commissioned and home ported in San
Diego, California, U.S.A. Built by
Northrop Grumman Ship Systems in
Pascagoula, Mississippi, U.S.A., the
vessel will be delivered to the U.S. Navy
in May 2008.
In 2006, GE delivered the first two
LM2500 modules for the U.S. Navy’s
newest Littoral Combat Ship (LCS).
Austal USA is building the ship at its
Mobile, Alabama, U.S.A., facility as part
of the LCS team helmed by Bath Iron
Works, Bath, Maine, U.S.A., a subsidiary of General Dynamics. The
team’s trimaran will feature two
LM2500s and two diesel engines in a
combined diesel and gas turbine
(CODAG) arrangement. In 2007, GE
will deliver two additional LM2500
modules for the second Bath Iron
Works/Austal LCS.
The Canadian Navy recently renewed a comprehensive maintenance
and logistics support agreement for the
LM2500-powered fleet of Halifax-class
patrol frigates. This agreement includes dedicated field service technicians and local parts support, and is
backed by GE’s extensive service and
depot network, providing on-site technical support.
In international markets, one
LM2500 in a CODAG arrangement will
power the Polish Navy’s next generation Type 621 corvette, to be named
Gawron. The new corvette will be built
by Poland’s Gdynia Shipyard, Warsaw,
Poland. Installation of the gas turbine
module is slated for June 2008.
In the Asia/Pacific region, GE-supplied LM500 gas turbine kits were
assembled and tested by Samsung
Techwin in the Republic of Korea (ROK).
The gas turbines, in a CODAG arrangement, will power a fleet of PK(X) class
patrol boats. The gas turbine modules
were installed in the first PK(X) vessel in
May 2007; sea trials are planned for
September 2007, with commissioning by
the ROK Navy slated for the end of 2007.
Commercial Applications
In the commercial marine sector, 26
GE marine gas turbines have logged
500 000 hours providing propulsion
and onboard service on 17 cruise ships.
The gas turbines are configured in two
different types of arrangements: 16
LM2500+ gas turbines are the basis for
