Aeroderivatives in the Spotlight

Published on: 

Aeroderivative gas turbines (GTs) are one of the growth areas in the turbomachinery sector. They are expected to grow in sales by 5% per year for the rest of the decade at least. Their flexibility, small footprint and reliability have made them popular in LNG, as peakers and as immediately available power on grids with a heavy concentration of renewables. So it is about time we gave them more attention.

Our cover story features a review of the many aeroderivatives available from GE, Siemens and Pratt & Whitney Power Systems (PWPS). Each of their models is described in detail. In addition, we cover the aeroderivative aftermarket. Vendors such as MTU Maintenance, EthosEnergy, RWG and Sulzer provide tips on how to maintain these machines and the various services they offer.

Beyond that, the issue includes plenty of worthwhile material. There is a feature on steam turbine maintenance, a look at a novel design for a combined cycle power plant, how 3D printing must evolve to serve the oil & gas sector, and where remanufacturing may be of value in turbomachinery. Moreover, our Myth Busters tackle the problem of rickety foundations, and Turbo Tips takes a look at hydraulic systems.


By the time you read this, two major shows will be upon us. The PowerGen show in Las Vegas and the Turbomachinery and Pump Symposium in Houston. We look foward to seeing you at one or both of these shows
