Gas Turbine Compressor / Generator package Integration

Turbo-generator and centrifugal compressors are key packages on any offshore plant. Because of their size, weight and cost, their integration on the deck is carefully studied.

The question of vibration risk is inevitably raised: what is really at stake, and what is the good approach to minimize the risk for workers, the package itself, and the neighboring equipment? Having been involved in dozens of projects over the 3 last decades, VibraTec will share this experience and present its methodology to study these packages and minimize risks at minimal cost.

Key topics that will be covered during this webinar on Thursday December 9th at 8:30 am CET:

  • Vibration risks for 3 types of package:
    Turbine driven compressors
    Turbine driven generators
    Centrifugal compressors driven by electric motors
  • Recommended analyses
  • Gimbals vs AVM supports

The webinar will end with a live Q&A session.

Railway R&D: VibraTec develops new methods to speed up acoustic certification

VibraTec and MicrodB actively contribute to railway R&D: In the TRANSIT project – part of EU-funded Shift2Rail Joint Undertaking (grant no. 881771) – we work on cost-effective acoustic certification.

Recently, we carried out a measurement campaign in Alstom’s laboratory in order to characterize the acoustic performance of a power converter. We used a Simcenter HD Acoustic Camera and a Simcenter Sound Camera developed by MicrodB in collaboration with Siemens to determine simultaneously and with high spatial resolution the sound power and location of the acoustic sources of the converter. In a next step we integrated the measured data into a full vehicle model in order to simulate the sound pressure received at ISO 3095 standard positions.

This approach makes it possible to assess a rolling stock’s acoustic performance during its design phase and thus to speed up certification procedures while reducing risks.

For more information contact Martin Rissmann or Lucille Lamotte and check out the TRANSIT website.

E-Silence: reducing e-powertrain NVH behavior without deteriorating performance or increasing cost

The E-Silence R&D project is developing optimization methodologies and solutions to tackle NVH issues, starting at the early design phase and going up to the prototype phase. Our optimization algorithms are able to test several thousands of motor topologies in a short period, ensuring a noise minimization which is robust regarding manufacturing tolerances.

We have already used these methods on several industrial applications: noise reduction is more than 10 dB, without any deterioration of the other global machine performances (torque, efficiency, etc), and without increasing mass and cost.

We also optimize stator potting material in order to reduce noise by 10 to 20 dB.

VibraTec is proud to coordinate the project with its partners Altair, Moving Magnet Technologies and research laboratories FEMTO-ST and L2EP.

VibraTec will present the E-Silence project at the CARA cluster’s online Automotive Techdays on June 1st: feel free to stop by our booth to talk with us about the project !

This project was partially financed by the European Union through the ERDF.

Indirect rail acoustic roughness measurements using an onboard system

Indirect rail roughness measurement makes it possible to estimate the acoustic quality of a railway infrastructure without space or time constraints. Several indirect measurement systems for rail acoustic roughness exist, based on different vibro-acoustic sensors. However, these systems present a number of limitations that VibraTec has overcome with its unique hybrid numerical/experimental approach.

Numerical simulations serve to select the best set of sensors (type, number and position), making it possible to overcome any potential frequency limitations. Numerical simulation also takes the influence of track dynamics into account. Experimental calibration completes the roughness measurement methodology.

This work was developed in the framework of the French project MEEQUAI (on-board MEasurement of railway Infrastructure Acoustic QUality). The project involved a partnership with the Joint Research Unit in Environmental Acoustics at the Université Gustave Eiffel (UMRAE) and the French national railway company SNCF.

Listen to Anna-Rita TUFANO’s presentation at the e-Forum Acusticum in December 2020.

Acoustic transparency of Alberich coatings under high water pressure: coupled simulation method

This innovative simulation method estimates the acoustic behavior of elastomeric coatings taking into account the influence of temperature and pressure conditions. The implemented procedure is based on the coupling between a nonlinear static simulation (taking into account the hyperelastic nature of the involved materials) and a linear acoustic simulation (taking into account the viscoelasticity of the materials).

This type of method is used for optimizing underwater coatings; VibraTec is an innovative player in the field.

The method is applicable to estimate the acoustic performance of any system incorporating elastomers under stress (seals, absorbent coatings, etc).

Fatigue Design 2017 Conference in Senlis (France) from the 29th to the 30th of November will be the occasion for VibraTec to present its work on AIV fatigue methodology.

Acoustic Induced Vibration (AIV) refers to the high acoustic energy generated by pressure-reducing devices that excite pipe shell vibration modes, producing excessive dynamic stress. Analysis of this risk is an important part of Asset Integrity Management systems as AIV can cause catastrophic piping failure. Existing guidelines address this risk through an analytical assessment. However, these methodologies are limited.

The proposed approach for identifying AIV damage is based on a dynamic stress evaluation at pipe discontinuities (welded connections and supports). This evaluation is performed through a fluid-structure coupling Finite Element Analysis. Pressure fluctuations inside the pipe are predicted and coupled with a pipe structural analysis. This methodology is provided with its validation through measurement on an actual AIV field case, corresponding to a crack initiation due to AIV.

AIV – FIV: VibraTec’s your one-stop piping expert !

Piping vibration can lead to severe damage to main lines & auxiliary systems (small bore, thermowells etc.): vibration can induce cracks & leaks, leading to heavy maintenance and even installation shutdown. Proper understanding of the phenomena at stake is essential to prevent and mitigate these risks. VibraTec is a world-class expert that can help you keep your major piping vibration issues under control.

This year’s SPE/IATMI Asia Pacific Oil & Gas Conference and Exhibition in Jakarta (and not Bali as initally planned) from the 17th to the 19th of October will be the occasion for VibraTec Asia Pacific’s Hafiz KARIM to present two papers based on case studies respectively in AIV diagnosis & mitigation (a cracked FPSO flare network tail pipe), as well as in discontinuity-related FIV issues in pipe system design.

The perfect time to come learn more !

VibraTec’s R&D is in the pipeline !

Singularities in industrial pipelines (such as section or direction changes) are often responsible for vibrations caused by continuous internal flow. To understand and model the complex fluid source, VibraTec has been conducting innovative research combining experimental methods, instationary fluid mechanic computations and statistic tools applied to reduced-scale models.

We are proud to be sharing an overview of current results at the « Congrès Français de Mécanique » in Lille from August 28th through September 1st. 2 presentations – a great occasion to meet you and discuss these issues.
