About our department


PulsimSuite software for API 618 / 674 pulsation and vibration studies, and root-cause analysis.


  • Pulsation and vibration control for process equipment, pipe systems, and rotating equipment (yearly three-day workshop in November, at the TNO office in Delft; also tailor-made courses available at customer location).
  • Flow assurance, focusing on number of topics such as multiphase flow assurance, control optimization, petroleum chemistry and well-reservoir interaction (bi-yearly three-day workshop in April, at the TNO office in Delft; also available at customer location).
