Siemens introduces SGT-A35 RB Gas Turbine for Oil and Gas Industry

Siemens introduces SGT-A35 RB, an aeroderivative gas turbine which can generate up to 38 MW meeting the need of more cost-effective solutions for the offshore oil and gas industry by increasing the power density of the topside power generating equipment and integrated into a compact, lightweight Dresser-Rand package, which is up to 30 percent smaller and lighter than Industrial RB211 predecessors.

The SGT-A35 RB gas turbine is based on the proven pedigree of the Industrial RB211 and Industrial Trent 60 gas turbines, built with Rolls-Royce Aero Engine technology. 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.

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.

Judy Marks, head of New Equipment Solutions for the Dresser-Rand business said that With the highest power density in this class they help offshore operators with a significant challenge. 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.
