Siemens introduces 38-MW aeroderivative gas turbine for oil and gas industry
• Evolved from trusted Industrial RB211 and Dresser-Rand legacies
• Up to 30 percent smaller footprint and lighter solution for offshore applications
• Highest power density in this class of turbines
The SGT-A35 RB variant introduces a lightweight free-power turbine derived from Rolls-Royce aerospace and marine Trent, as well as Siemens Industrial Trent 60. All rotating components are proven by millions of hours accumulated in flight, as well as industrial and marine service.
The SGT-A35 RB gas turbine is available in 34 and 38 MW variants to match a range of application requirements. Both ratings are available for mechanical drive and 60 Hertz or 50 Hertz electrical generation. In this configuration, the gas turbine can directly drive a 2-pole A/C generator without the need for a gearbox. The thermal efficiency of the gas turbine exceeds 40 percent at ISO conditions. The performance is ideal for hot climates and at 30 °C, the gas turbine retains more than 90 percent of its ISO power output.
The Dresser-Rand package uses fit-for-purpose packaging features and configurable options proven across oil and gas applications. Its modular design facilitates easy maintenance and reduces downtime to maximize availability and reduce clients’ operating expenditures. The package has also been designed to quickly exchange the complete gas turbine and power turbine. Over the years, the Dresser-Rand business has supplied more than 1,000 aeroderivative gas turbine packages to the oil and gas industry.
“With the highest power density in this class we help offshore operators with a significant challenge,” said Judy Marks, head of New Equipment Solutions for the Dresser-Rand business. “With gas turbines used as prime movers in offshore installations, project developers can simultaneously reduce capital investment and increase production capacity to achieve desired returns.”
