Simulation and Analysis of Pulsations

BOSpulse is a professional software solution to perform a pulsation analysis of reciprocating equipment. BOSpulse makes it possible to model custom or predefined reciprocating equipment and the attached piping, perform a pulsation analysis and check the results against the allowable pulsations prescribed by the API standards (i.e. 618/674). BOSpulse can also export the periodic forces resulting from acoustic resonance to perform a mechanical response analysis using a pipe stress program like Caesar II.


“BOSpulse provides a complete solution for engineers looking for tool to solve their acoustic and mechanical response problems for their reciprocating equipment.”

Software Capabilities

With BOSpulse engineers can perform a pulsation analysis for reciprocating compressors according to the API 618 standard or for reciprocating pumps according to the API 674 standard. The API standards specify the allowable pulsation levels on a per frequency basis, so each harmonic component of pressure profile must be evaluated separately. Using BOSpulse the pressure profile can be decomposed into multiple harmonics of the machine base frequency for a quick and easy assessment of the results.


  • API 618 allowable pulsation check
  • API 674 allowable pulsation check
  • Predefined reciprocating compressors
  • Predefined reciprocating pumps
  • Valves, check valves, surge vessels
  • Harmonic decomposition of pressure signals

Already built your model in another (stress) package?


BOSpulse can import CII files (CAESARII neutral files) thereby preserving the original node numbering. This allows stress engineers to use models built in any software packageCAESAR II
that supports the CII format in order to calculate the unbalanced forces induced by water hammer or reciprocating equipment for example. The calculated results can easily be transferred back to evaluate the mechanical effect on the piping structure.

Licensing, Support and Training

BOSpulse is available in two license types; a Standalone license and a Network license.  To provide you with flexibility, the license can either be purchased or leased. For a price quotation please fill out the Information Request Form. To experience BOSpulse immediately, please fill out the Demo Request Form and a link to download our free demo version will be sent to you.


Every purchase of BOSpulse includes support which covers installation and basic software questions. If any issues are encountered during the installation procedure or the use of BOSpulse, contact us by phone during business hours (Monday to Friday, 9:00AM to 5:00PM [GMT+1]) or by e-mail. When submitting a support request via e-mail, we highly recommend you to include your model file along with your support request. This will give our support team the best chance of providing a thorough and quick response.


DRG has a profound knowledge of pulsation projects, with a team of engineers who use BOSpulse on a regular basis. In case you are interested in additional modeling support or the construction and/or analysis of a complete piping model by DRG. Contact us for information by e-mail.


For future and existing users of BOSpulse we also offer a 2-day training course. The training course is intended for engineers involved with pulsation analysis in piping systems. Participants will be introduced to the theoretical background of pressure pulsations due to reciprocating equipment and API regulations and will be shown how to perform pulsation analyses using BOSpulse. Please visit our Training Courses webpage or contact us by email for more information.
