CCPGE has been awarded a project for API 618 pulsation (acoustical), mechanical, torsional vibration and skid structure analysis of COOEC Lingshui 17-2 reciprocating compressor packages. The Lingshui 17-2 project includes a two-stage compressor skid and a three-stage compressor skid, where two different types of Ariel compressors are deployed. The success bid of this project indicates that the cooperation between CCPGE and CNOOC has entered a steady development stage.
