完整的内部功能

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 bearing. Hence, the DGS solution was the only way to enable oil-free configuration in sour service. The turboexpanders and moto-compressors were completely assembled and tested in-house, leveraging our internal capability for magnetic-bearing tuning and testing resulting from the agreement with SKF.
