GT13D Turbine and Compressor Upgrades BOOST PLANT AVAILABILITY AND REVENUE


Since its introduction in 1975, GE has continued to invest in the GT13D fleet. We now offer a comprehensive product portfolio to sustain its competitiveness.


The GT13DC compressor upgrade was designed specifically for the GT13D original turbine to increase the performance and improve the surge margin under severe ambient conditions, making it particularly beneficial for plants in hot countries. With this upgrade you retain the GT13D’s excellent mantainability while gaining the ability to apply further modular upgrades (GT13DMC). Additional benefits include:


• Increased gas turbine performance by up to 7%


• Improved gas turbine efficiency by as much as 0.9% (multiplicative)


• Improved surge margin (approximately 10° C) • Increased availability and reliability


Sustain the future competitiveness of your GT13D turbine A-Visual

with the modular GT13DMC turbine and compressor upgrade package. Thanks to two different operation modes, one for more power output and efficiency (P-mode) and the other for longer inspection intervals (L-mode), the upgrade provides an additional performance and availability boost. Key advantages include:


• Increased gas turbine performance by up to 19 MW (P-mode)


• Improved gas turbine efficiency by as much as 2.2% (P-mode)


• Enhanced flexibility due to switchable operating modes for enhanced extended lifetime or extra power output and efficiency


• Reduced maintenance costs due to extended C-inspection intervals of 32,000 EOH (L-mode)
