BOSpulse Foundations: Pulsation Analysis

About The Course

This course equips engineers with fundamental knowledge of pulsations in piping systems and demonstrates how to assess them according to API 618 and API 674 codes. It is designed for professionals engaged in acoustic and mechanical design for piping related to reciprocating equipment. Participants gain a solid theoretical foundation in pulsation analysis and become adept at conducting code-compliant assessments using BOSpulse.

The course delves into effective mitigation techniques for excessive pressure pulsations, providing detailed guidance on analyzing these mitigations with BOSpulse.

Participants will gain a thorough understanding of dampener configurations, bottles, and other pressure suppression methods using BOSpulse.

Upon completing this course, you will be a confident BOSpulse user with expertise in sound design practices and the analysis of water hammer phenomena in piping systems.

The course is available in multiple formats. For individual learning, you can choose to follow the course online at your own pace. For teams there are also instructor led training course options, which can either be followed online or through a 2-day class-room training.
