Complete in-house capabilities
For a 2019 offshore platform project in the North Sea involving seven of our single shaft, high-speed moto-compressors with active magnetic bearings (AMB), we also delivered two AMB expander compressors with dry gas seals (DGS). Service is characterized by high H2S content not compatible with magnetic bearings. Hence, the DGS solution was the only way to enable oil-free configuration in sour service. Assembled and tested in-house, our turboexpander compressors leverage our internal capability for magnetic-bearing tuning and testing resulting from the agreement with SKF.
