About the course

This course teaches you fundamental knowledge and understanding of pressure pulsations in piping due to reciprocating compressors in the context of API 618 analyses.

By means of several real-life case studies you are thought the details of how pulsations are caused by compressors and what their consequences can be. Associated assessment methods such as pulsation analysis using software are discussed by the instructor as well as conformity checks for the pulsations and resulting vibrations. Possible mitigation measures and good design practices are provided.

Discussions and analyses will be illustrated using the software BOSpulse. No knowledge of this software is required.
