Siemens Presents New Lightweight Aero-Derivative Gas Turbine for Oil and Gas Industry

Siemens RB211-GT30 gas turbine optimized for oil and gas industry

Siemens (NYSE: SI) has unveiled a new lightweight aero-derivative gas turbine optimized for offshore applications of the oil and gas industry.

Based on the Industrial RB211 from the former Rolls-Royce Energy portfolio, which has accumulated more than 34 million hours in service, the RB211-GT30 gas turbine features a package design that is 30 percent smaller and lighter than previous technologies.

Among the turbine's features, a three-point base mount and torque tube design.  The turbine drives a two-pole AC generator at either 60 Hz or 50 Hz with no need for a gearbox, with savings in weight and footprint.  The package is optimized for offshore duty to facilitate safe maintenance and reduce downtown, and it can be removed from either side of the package and exchanged in less than a day.

The auxiliary systems are functionally unchanged but have been optimized to improve maintenance access and maximize online maintenance while the unit is running.

The RB211-GT30 is the first new product to emerge from the union of Rolls-Royce Energy and Dresser-Rand, which together previously supplied a significant share of 20- to 40-MW offshore power generation on floating production storage and offloading vessels (FPSOs) worldwide.
