For compressors below 750 RPM the study is conducted per API 618 requirements, the pulsation and vibration standard for slow speed compressors.
For higher speed compressors, the GMRC High-Speed Compressor Guideline and API RP 688 are used to define the vibration requirements. The GMRC guideline is based on the API standards but has been augmented for the unique requirements of higher-speed compressors.
