Dresser-Rand Group, Inc. ("Dresser-Rand") (NYSE:DRC), a global supplier of rotating equipment and aftermarket parts and services, announced that it will supply a VECTRA 40G generator package to Siemens Oil and Gas Offshore/Sevmorneftegaz for its Prirazlomnaya Project.

This is the third VECTRA generator package to be delivered to this platform since the fall of 2005. Once installed, all three packages will run together to meet increasing offshore power demand.

The Dresser-Rand VECTRA 40 power turbine was developed to be compatible with the GE LM2500+ gas generator. Together they offer the most effective power package available for high-speed operation. As part of a complete package with the GE LM2500+, the VECTRA turbine has an ISO rating of 40,200 horsepower (30 megawatts). Thermal efficiency is 39.9 percent at full load, with a corresponding mass flow to 180 pounds per second. The VECTRA 40 has a maximum continuous operating speed of 6,500 RPM -- the highest for a power turbine that is available for use with the GE LM2500+.

The VECTRA 40 power turbine's modular design improves serviceability while reducing downtime. It can be installed and removed as a unit, either separate from, or with the gas generator. Such design advantages can produce significant operational savings to clients during the extended life cycle of the units.

"The VECTRA power turbine provides a cost-effective solution for clients," says Dan Lowry, vice president, Client Services for Dresser-Rand. "It requires a reduced maintenance area and is far lighter than earlier power turbine designs, so platforms can be designed to be smaller and lighter. Furthermore, the power turbine module is not required at the time of platform construction. The module can arrive on site just before commissioning without affecting the overall project schedule."
