Pulsations And Vibrations: Reciprocating Compressors

About The Course

This course imparts fundamental knowledge of pressure pulsations in piping, particularly in the context of API 618 analyses related to reciprocating compressors. Through real-life case studies, you will gain insights into the origins and potential implications of pulsations caused by compressors.

The instructor will cover assessment techniques, including pulsation analysis using software, and guide you through conformity checks for pulsations and resulting vibrations. Additionally, the course addresses possible mitigation measures and best design practices.

Practical discussions and analyses will be demonstrated using BOSpulse software, with no prior knowledge of the software required.

This course is self-paced and is not subject to specific dates. The course contains 4 modules with a total of 2.5 hours of content which can be performed at your own pace. A personal certificate will be provided to you if you finish the course within the first month after purchase. This incentive aims to motivate you to perform the course on time, thereby improving your learning curve.


This course is scheduled over a 1 work day. The dates of the course are organized upon inquiry.

This course is available in self-paced, and classroom formats.

Prerequisites and level

  • Basic understanding of piping systems. 
  • Discussions and analyses will be illustrated using the software BOSpulse.
  • No knowledge of this software is required.
  • Level: Intermediate

Intended For

This course is designed for:

  • Anyone working piping systems connected to reciprocating compressors.
  • Those involved with piping systems prone to vibrations.
  • Engineers working with the API 618.

Access to the self-paced course

After your purchase is confirmed you receive an account to the EngineeringTrainer online learning portal, where you can find the course in your dashboard. After opening the course you will be guided step-by-step through the different modules. You receive 1-year unlimited access to the course, allowing for the repetition of modules as desired.

Learn by doing

The course is mainly based on video content: video lectures and video software demonstrations. English subtitles are available and videos can be viewed as many times as desired. The video lectures help you to grasp the important technical concepts and in the video demonstrations the instructor uses the software and discusses all the steps and actions. You are recommended to follow the steps of the instructor in the software to optimize your learning curve.

The classroom course is performed in person either on-site or in the Dynaflow Research Group office located in Rijswijk, The Netherlands. This course enables you to be face-to-face with the instructors with live examples provided. This course also provides all participants with a 1-year access to the self-paced course.

Exercises are available in the form of multiple-choice quizzes to help you grasp technical concepts and in the form of .pdf files with instructions to build and analyze different models and answer related questions. Video demonstrations of the exercises are available.

Participants of the self-paced course receive a personal digital certificate if they meet the following requirements:

  • Completion of each course module
  • Filling in the course evaluation survey

Participants of the classroom course receive a personal physical certificate upon the completion of the course.

Example certificate:
