We build a relationship with you. We know how important it is to have seamless communication directly with your dedicated RWG project engineer, who knows your equipment inside out.

SGT-A35
With more than 700 in service today, the industrial aero-derivative SGT-A35 gas turbine continues to play an integral role in powering offshore installations and power plants around the world. It was introduced to the market by Rolls-Royce in the 1970s, has a modular design for more efficient maintenance, and produces around 33 megawatts of power.
Weighing in at two and a half metric tonnes, and measuring just under three metres in length, it is considered one of the most reliable gas turbines available for both power generation and offshore applications.
The Dry Low Emissions (DLE) version of the Industrial RB211 entered the marketplace in 2004, with all the power capacity of the original version, but a much improved environmental performance, producing reduced NOx and CO emissions in operation.
“All work was executed on time and to a high level of professionalism. It was a pleasure working with RWG on the overhaul and I look forward to the next one.”International Gas Transmission Company

Component repair is our specialty and our in-house technology is second to none. We offer a comprehensive suite of repairs and processes that enhance the service life of your gas generator components.
We can meet all of your SGT-A35 spare parts and inventory management requirements for mature engines and the latest models alike.

Gas generator advance exchange
We provide an advance exchange option for operators who don’t have the luxury of time or rotable assets within their fleet. Typically, this service requires assembly and configuration of an exchange gas generator in advance of a planned maintenance event.
We’ll ship the replacement engine to you ready for immediate exchange and matched to your site specific configuration. Our service option can include installation and commissioning to minimise plant downtime and let you resume business operations with minimal disruption.
