Siemens presents new lightweight aero-derivative gas turbine

Siemens has introduced a new gas turbine, the Industrial RB211-GT30, to the market that is optimised for the needs of the oil and gas industry, and its offshore applications in particular. The machine is based on the proven Industrial RB211 gas turbine from the former Rolls-Royce Energy portfolio.

Previously, Rolls-Royce Energy and Dresser-Rand groups have supplied a significant share of the 20 to 40 MW offshore power generation on FPSOs worldwide. Now Siemens will use this combined expertise to offer compelling solutions for the offshore market. The Industrial RB211-GT30 is the first new product to emerge from this union of experience and expertise.

The Industrial RB211 has accumulated over 34 million hours in service, and its features include:

• The Industrial RB211-GT30 gas 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 has a new lightweight construction that is 30% smaller and lighter than its predecessor. It is designed specifically for offshore duty, with a three-point base mount and torque tube design.
• The package has been optimised to facilitate safe maintenance and reduce down time, even in challenging offshore conditions. The complete gas turbine can be removed from either side of the package and exchanged in less than 24 hours, thanks to an innovative rail system built into the package itself.
• The auxiliary systems are functionally unchanged, but have been optimised to improve maintenance access and maximise online maintenance while the unit is running.

“With our Industrial RB211-GT30, we’re introducing a new benchmark in power generation solutions for the global oil and gas industry, especially for FPSOs,” stated Thomas Flommersfeld, Head of Strategy and Portfolio Management in the Distributed Generation Business Unit of Siemens. “Joining forces with Dresser-Rand to ensure maximum proximity to our customers, we’re offering the latest evolution of the trusted Industrial RB211 aero-derivative technology, enhanced to set new standards of power density, reduced down time, and easy maintenance.”
