Rolls-Royce launches gas turbine upgrade

Global power systems company, Rolls-Royce has launched RB211-Gzero, a retrofit upgrade product that provides many existing users of industrial RB211 aeroderivative gas turbine engines with increased power of ten per cent depending on ambient temperature and engine type.
“The RB211 is the most reliable and easily maintained industrial gas turbine available in its class today. The new RB211-Gzero delivers an additional ten per cent more power that will be critical to boosting performance and profitability for our customers in the global power generation and oil & gas sectors,” said Scott DeWolfe, Rolls-Royce, RB211 Product Director, Energy.

The RB211-Gzero product is specifically designed to benefit operators of the 440-plus worldwide installed fleet of RB211-C and RB211–G variant gas generators that feature RT-56 or RT-62 power turbines.
By retrofitting applicable RB211 units with a modular package that increases the flow of air through the engine, thereby increasing power availability at ISO conditions by 10 per cent for the RB211-G, and up to 31 per cent for the RB211-C, depending on existing package configuration. This simple retrofit approach requires minimal modification to the existing gas turbine and also ensures that oil & gas production and power generation facility down-time is kept to a minimum.
With over 700 units sold, recording over 30 million operating hours, the industrial RB211 gas turbine is available in a power range of 29 to 44 megawatts and provides an ideal solution for onshore and offshore oil & gas and power generation applications.
