Siemens: new core engines for gas turbines

With over 850 units sold and more than 88 million fleet operating hours, Siemens TB5000 industrial gas turbines are some of the most reliable and hard-working turbines in their class. In an effort to extend the lifecycle of these proven units even further, Siemens has developed new and improved TB core engines. The new core engines, of both TB4900 and TB5400 ratings, will adopt the latest technology designs and enhancements from Siemens' current small industrial gas turbine portfolio, including performance and efficiency improvements for low ambient operation.

First introduced for commercial application in 1970 and retired from the company's new product portfolio in 2002, the TB5000 product line offered high reliability and long life, characteristics associated with well-designed turbo machinery. Many of the units are operating in challenging climate conditions, such as in the deserts of the Middle East and in the low temperature environment of the Alaskan North Slope.

Based on the size and age of the operating fleet, Siemens recently determined the majority of these units could benefit from newly designed core engines and has set out to build and assemble the first 20 at the Siemens Service Product Centre of Competence in Aberdeen, Scotland. The modernised core engines and new control system upgrades will also provide customers the opportunity to lower overall costs by reducing the need to replace parts as frequently in the aging machines. Siemens has introduced a new blade and disc design for the compressor turbine section, eliminating the method of blade retention through material deformation. This new method simplifies the assembly process and draws on the proven technology of the modern gas turbine, underpinning the future of the long-proven TB product.

"Helping our customers extend the lifecycle of their investments with technology upgrades such as these new TB core engines underscores our commitment to the long-term support and improvement of our technologies and to our continued investment in R&D," said Thorbjörn Fors, CEO of Siemens Power Generation Services, Distributed Generation business unit.

Installation of the new core engines is set to begin in early 2016.
