MS5002E Gas Turbines
PERFORMANCE
The most recent addition to the GE family of gas turbines is the MS5002E which delivers high
efficiency, low environmental impact and high reliability. This dual-shaft gas turbine has proven its
capability for use in power generation and mechanical drive applications.
The MS5002E uses GE’s state-of-the-art combustion technology (DLN2.5H) which has accumulated
more than 14 million firing hours in the “F/FA” Class GE Frame gas turbine. This model was designed to
maintain or exceed the availability and reliability of previous Frame5 models. To maximize hot parts life
duration, the firing temperature was kept approximately 100°C lower than that of the “F/FA” Class.
Superior efficiency was achieved through the use of advanced design tools to optimize airfoils (for both
axial compressor and turbine sections), clearances, leakages and the distribution of cooling flows.
Compared to the MS5002C and D or MS5001, the efficiency gain of the MS5002E results in a reduction
in emissions of over 20,000 tons of CO2 per year, equivalent to the amount of C02 absorbed by 20 sq
km of forest in a year. In addition, the MS5002E NOx emission level is down to 18 ppm. These
achievements make the environmental impact of the MS5002E the lowest in its class.
The design of the MS5002E was thoroughly validated through an extensive test program that included
a full scale test of the axial compressor, and full scale rotordynamic testing and full load testing of the
gas turbine system in both mechanical and generator string tests.
The MS5002E is ready for the Oil & Gas market and will provide customers with the benefits of a long
lasting and reliable machine combined with low environmental impact and low operating
costs. The first requisition unit will start at the customer’s site in September of ‘07.

POWER TURBINE
Package
- Completely mounted on a single base plate
- The enclosure is integral with the base plate
providing maximum accessibility for maintenance
of the gas turbine and auxiliaries
The PGT25 power turbine components were designed taking into account many years of
experience gained in the field by heavy duty gas turbines and axial/centrifugal compressors. The
aerodynamic blading was designed with the main objective of obtaining very high efficiency at
both design and reduced speeds.
The 6500 RPM design speed means the turbine can have two stages with a moderate
aerodynamic load and a high expansion efficiency. The two expansion stages are of the high
energy, three-dimensional design type.
The investment casting superalloy selected for the blading assembly has a cobalt base for the
nozzles and a nickel base for the rotor blading (i.e., the same materials used on heavy-duty gas
turbines). A large creep and fatigue (LCF-HCF) safety margin on blade life is ensured by a
moderate gas temperature at the power turbine inlet. The two-stage rotor is overhung and the
shaft is supported by two tilting pad bearings contained in a cylindrical cartridge. The system
can be easily dismantled with a simple translation of the gas generator within the package
space thus reducing the time required for a major overhaul of the power turbine to a few days.
Engineering simplicity and advanced materials yield long time between overhauls and reduced
maintenance costs.
The turbine is assembled on a light but rigid base plate with extensive use of prefabricated
standard components preassembled and tested in the shop to minimize on-site assembly time.

GE Gas Turbines
Main Components
Heavy Duty Axial Compressor
The compressor rotor is made of separately forged wheels (all models except part of the GE10
which has a solid forged rotor). Each individual wheel undergoes inspection and is X-rayed for
material flaws. In addition, each wheel is balanced individually and the rotor is balanced on three
planes. Rabbet fits are used to ensure concentricity and multiple through-bolts secure the wheels
to form a correctly pre-stressed assembly. The blades are held in the compressor rotor and
stator rings by dovetail platforms. The stainless steel blades provide excellent corrosion
resistance and good internal damping characteristics. The large chord, broad-blade compressor
blades have low stresses and the unique ability to withstand damage by small foreign objects as
well as to maintain high performance in spite of normal wear and contamination. The stator
casing is horizontally split for ease of assembly, maintenance and inspection. Iron castings give
dimensional and thermal stability to maintain good radial tip clearances for maximum power and
efficiency. Several compressor designs are available covering pressure ratios from 8:1 to 17:1 and
air flows from 20 to 400 Kg/sec with 11-17 stage configurations. The GE10 and MS5002E
compressors have variable geometry, implemented by means of adjustable vanes (inlet guide
vanes and first stage stator vanes), in order to provide flow control within the operating range.

GE Gas Turbines
Heavy Duty Turbine First Stage Nozzle
The complete first stage nozzle assembly consists of airfoil-shaped vanes which are contained
between an inner and an outer sidewall. The design of the nozzle assembly and the arrangement
for its support within the turbine shell accommodate the effects of thermal expansion caused by
the hot gases and keep the assembly properly aligned in the gas path. Seals in the turbine
shell prevent leakage of combustion gases around the nozzle from the inlet to the
exhaust. Compressor discharge air is fed to these sealing rings through orifices in
the shell. A key feature of the first-stage nozzle is the air-cooled partition which
increases nozzle life substantially. Cooling air from the compressor discharge is
directed through the body of the individual nozzle partitions, exiting through
holes near the trailing edge. This not only cools the metal, but blankets the
trailing edge with a film of air. Additionally, relatively thick nozzle partition
trailing edges provide increased strength and oxidation resistance, again
providing longer nozzle life.
Heavy Duty Turbine Buckets and Wheels
The long shank bucket design lowers the turbine wheel rim a substantial distance below the hot
gas path. The high thermal resistance of the shank results in a considerable temperature drop
between the hot bucket vane and the wheel dovetail slot, thus reducing temperature levels and
gradients in the turbine wheel and the dovetail area where rotating stresses are high. Further
wheel protection is provided by radial seals on the first-stage bucket shanks that restrict hot gas
leaks into the wheel cavities. Compressor bleed air is used to cool the wheels and maintain
relatively low temperature levels.

Gas Turbine Operability
Large Operability Window
A variety of innovative design solutions are offered to maximize the operability window of the Oil
& Gas heavy duty gas turbine fleet. In addition to variable stator vanes and blow-off valves, the
design solutions include:
- variable turbine nozzle guide vanes
- a variable bypass combustion chamber
- a high turn-down capability combustion chamber
- corrected parameter control logic
The various combinations of design solutions are specifically adapted to the demands of the
marketplace for each gas turbine model.
For example: The GE10-2 DLN (Dry Low NOx) model utilizes a variable bypass
combustion chamber to maintain the optimum flame temperature for low emissions
all the way down to 50% load, and the variable nozzle guide vanes of the free power
turbine to ensure that the gas generator shaft speed is always at the design value,
thereby ensuring maximum output.
The MS5002D instead uses variable nozzle guide vanes to maintain maximum
output on the standard model, and to maintain the optimum flame temperature
for low emissions down to 50% load on the DLN model. They are also used in
regenerative cycle applications to maximize the efficiency of the regenerator and
hence, to maximize fuel economy.
The MS5002E makes use of the DLN2 combustion design used in GE’s
F-Class machines to ensure low emissions over a range of flame temperatures,
thereby delaying the opening of the bleed valves at part load while maintaining
the highest possible efficiency at base-load.
Note that the flexibility given by each of these solutions delivers a further
performance advantage on cold days with respect to other engines that are forced
to open bleed valves (to meet environmental emissions laws) even at base-load.

CPC Logic
One of the enhancements recently introduced is the Corrected Parameter Control logic (CPC).
This type of control philosophy applies principally to mechanical drive units, and consists of an
exhaust temperature control curve that self adjusts according to the condition of the inlet filters
and actual power turbine speed. This allows the engine to be operated at optimum conditions
not only at the nominal point, but over the entire operating envelop of inlet conditions and
power turbine speeds. The results of this improvement have already been proven in the field,
and are shown in the following figure (relating to the test of a GE10-2 unit at various free power
turbine speeds). Through the application of CPC logic it has been possible to significantly
increase the maximum output without compromising the safe operation of the unit by simply
optimizing its operation in real-time.
The variable free power turbine speed element of the CPC logic is a standard feature of MS5002D
DLN and MS5002E models, and all new GE10-2 units. The retrofit of existing gas turbine models
with this solution is also offered.

Gas compression is a critical operation in the Oil & Gas production chain. Therefore, reliability is a
key factor in the design of our natural gas compressors.
We have delivered over 200 compressor trains for gas re-injection and gas storage applications.
Of the more than 380 casings supplied, 105 have a design pressure higher than 7,200 psia (500
bar a). Our many years of experience in designing, manufacturing, installing and servicing these
machines has validated GE designs and production processes. Reliability of this rotating
equipment is directly related to rotor stability and impeller integrity throughout the entire
envelope of operating conditions and our machinery has been successfully proven by long years
of service under the challenging conditions found in the Oil & Gas Industry.
The high level of power involved in these compression applications requires gas turbines as
drivers. GE provides a complete range of mechanical drive gas turbines that are ideally matched
to Oil & Gas applications. The extensive use of the GE MS6001 and MS7001EA single shaft gas
turbine technology for LNG mechanical drive applications is a result of our plant integration
services and the ability to optimize the design of both the gas turbine and the compressor for
these applications. The result is flawless performance of turbocompressors that have
accumulated more than 100,000 hours of operation in the largest LNG plants in the world.
Our ability to integrate, test and deliver the entire turbocompressor train is a great advantage to
the Customer in terms of the optimization of system performance and delivery time, as well as
the efficiency of working with a single supplier.
