GE Vernova offers a choice of various modular construction options that provide the degree of prefabrication that best fits your specific project site requirements. GE Vernova provides four basic options of prefabricated pressure parts modules:
Harp Bundle
Limited infrastructure
Limited large crane availability
Low site labor costs
Modules
Suitable for most sites
Fewer transportation restrictions
Large crane availability
Medium site labor costs
C-Frame
Sites with good water access
Large crane availability
High site labor costs
Fully assembled
Sites with excellent water access and specialized transport
High site labor costs
Horizontal Once Through (OT)
The Horizontal Once Through has the same basic arrangement as the Horizontal Drum, but eliminates the High Pressure Drum while using GE Vernova’s in-house OT technology to increase flexibility, efficiency and daily cycling capabilities.
Proven experience with over 2.5 million operating hours
Superior off design engineering and part load performance due to the ability to vary feedwater flow resulting in increased combined-cycle efficiency compared to drum type
Increased combined-cycle efficiency due to the ability to operate at higher HP steam pressures
Stable operation from low load to baseload with superior cyclic operation and flexibility compared to others
