Retrofit Kit First Cat Dual Fuel Oil and Gas Product to Enter Market

Business Wire

HOUSTON -- December 06, 2012

Caterpillar Inc. today announced it has shipped the first unit of the Dynamic
Gas Blending retrofit kit to a Russian oil and gas company. The dual fuel
product is now available for order from the Cat dealer network. As announced
previously, the Dynamic Gas Blending kit allows customers to reduce fuel costs
and meet changing emissions regulations by utilizing a wide range of gaseous
fuels in their existing diesel generator sets. The kit also recently
successfully completed an extensive field test for Encana Oil & Gas (USA) Inc.

The Dynamic Gas Blending kit automatically adjusts to changes in incoming fuel
quality and pressure allowing engines to run on a wide variety of fuels, from
associated gas to vaporized LNG with no loss of performance integrity. It
maintains diesel performance levels with up to 70 percent replacement of
diesel with gas, accepts up to 55 percent inerts. No customer input or gas
analysis is needed during operation, and no recalibration is required when the
equipment is moved or the gas supply changes. No testing is required at rig
construction or rig up.

“This is a completely integrated solution that continually adjusts to varying
fuel quality and requires no adjustments or re-testing, allowing the engine to
run at maximum substitution while maintaining a high level of reliability and
durability,” said Sam Ternes, Caterpillar Global Petroleum engineering
specialist.

Designed for compatibility with existing land drilling rig controls and
production multi-generator set control systems, the gas blending kit provides
robust transient response and an integrated gas induction control which
maintains stable generator output. It is easily integrated with drilling and
production generators in the oil and gas industry.

The Dynamic Gas Blending kits include Caterpillar’s newest control system –
EMCP4.4, which easily integrates the engine, generator and the gas blending
system. Features of the EMCP4.4 include:

  * Plain text display of fault codes
  * Compatibility with customer inputs through MODBUS protocol and load
    sharing modules
  * Easy-to-view gas system parameters, simple daily walk-around inspections
  * Engine protection shutdown/startup ability with custom programmable alarms
  * Compatible with legacy direct rack control systems

“The fuel savings achieved with this system depends on a number of variables,
including the application, the quality of the gas, the pressure and available
volume,” said Russell Goss, Caterpillar Global Petroleum engineering
specialist.

The gas blending kit includes an emergency stop purge cycle, generator
temperature monitoring and air shut-off valves. If fault codes are detected in
the gas system, it will be shut down and the system will seamlessly revert to
full diesel operations. To learn more about the DGB solution, please visit the
