CCPGE was awarded a contract for API 618 pulsation (acoustical), mechanical, torsional vibration, skid and offshore platform /FPSO supporting structure analysis of COOEC Liuhua 16-2 and Lvda 16-3 reciprocating compressor packages. The Liuhua 16-2 compressor packages are mounted on the FPSO in South China Sea, where the roll, pitch and heave of FPSO are considered in the vibration analysis. The Lvda 16-3 compressor packages are mounted on an offshore platform in Bohai oilfield, the platform supporting structures are included in the vibration analysis. The purpose of this vibration analysis project is aimed at eliminating the potential pulsation and vibration problems of compressor packages and optimizing skid and platform/FPSO supporting structure design.
