Reducing Space in Offshore applications for Centrifugal compressors

Banchi, Nicola

High Pressure Ratio Compressor (HPRC), it is a new type of compressor architecture that aims to increase the compression station compactness by reducing the number of compressor bodies, in particular for offshore markets provides a great benefits reducing weight, minimizing footprint and installation time. GE’s HPRC technology is based on an innovative architecture that combines unshrouded and shrouded impellers on a single high-speed shaft to achieve pressure ratios and efficiency levels higher than other available technologies. As result of the increased head per stage, HPRC units have a shorter bearing span that reduces the number of casings required. Applications that would typically require multiple compressor bodies will only need one with HPRC. Individual HPRC units are already
