BOSpulse Foundations

Pulsation Analysis

About the course

This course teaches you the fundamentals of pulsations in piping systems and a how to assess these pulsations based on the API 618 and API 674 codes.
The course is intended for engineers involved in the acoustic and/or mechanical design of the piping upstream or downstream of a reciprocating equipment. You will be introduced to the theoretical background of pulsation analysis, and will become acquainted with conducting a code conformance analysis for reciprocating equipment using BOSpulse.
Effective mitigation methods are covered for excessive pressure pulsations and the analysis of these mitigative actions using BOSpulse. Detailed explanation of the effects of dampener configurations, bottles, and other pressure suppression methods are provided using BOSpulse.
After this course you are a confident user of BOSpulse which understands good design practices and analysis methods for water hammer phenomena in piping systems.
