Are you sure that the condition of your natural gas assets is such that the dynamic effects of pulsations and vibrations cannot damage your pipework or affect the mechanical integrity and safety of your gas manifolds? And do you know how pulsations and vibrations can affect your metering and control systems? Do you have plans to start operating your gas pipe systems beyond operational design ranges? Find out how to design and operate your gas stations to minimise integrity and safety risks. Learn how to use simple design tools for new gas assets or judge whether your existing gas assets can still be operated safely in conditions beyond original design.DNV GL offers this one day course to improve awareness about the risk of pulsations and vibrations and to identify the parameters and aspects which are necessary to control this risk and bring it to an acceptable level.
This course provides a good general overview of gas flow acoustic and vibration principles and practices. Participants will become aware of possible problems in the design and operation of gas piping systems. Moreover, practical tips and tricks on vibration and pulsations prevention will be shared.
For more information and for registration, please refer to the leaflet.
We also provide training on gas, gas flow and gas metering principles.
On request, DNV GL can also provide an in-house training course in English or Dutch. Content, location and duration of the course can be adapted to your specific wishes. Please contact us for more information.

Those responsible for the operation and maintenance of gas assets, such as compressor stations, pressure regulating stations and other gas assets with piping manifolds (gas asset managers, mechanical and electrical engineers, design engineers, station operators, service staff and inspectors). The course can also benefit anyone involved in the design, engineering and troubleshooting of pulsation and vibration in gas stations or those wishing to extend the operation beyond design conditions.
Participants should possess certain basic knowledge of gas flow and gas transmission systems.
