Veridian VS

Vibration screening can now be done quickly and efficiently with significant cost savings for operators.

Veridian VS is a free, web-based screening tool used by owners, operators and engineering consulting firms to identify high-risk locations in process piping systems. This stand-alone tool is used to improve the design of piping systems, to support inspection and measurement activities, and for vibration integrity programs.

Risks evaluated by Veridian VS

Veridian VS identifies and evaluates potential excitation mechanisms that can result in piping vibration fatigue failures, such as:

  • Flow-induced turbulence (FIT), including multiphase excitation
  • Mechanical excitation from connected or nearby machinery such as reciprocating compressors or centrifugal pumps
  • Pulsations caused by reciprocating pumps and compressors
  • Pulsations caused by centrifugal compressor rotating stall
  • Flow-induced pulsations caused by deadlegs in the piping system (deadleg pulsations, FIP, or FIE)
  • High-frequency acoustic energy created by pressure reducing devices (AIV, AIE)
  • Transient-caused valve operation (surge, water hammer, relief valve reaction forces)
  • Cavitation and flashing of liquids




Other features include:

  •  Full qualitative and quantitative approaches
  •  Tabular output and standard reports
  •  Built-in design recommendations
  •  Scalable: from small to large facilities, and for multiple sites
  •  Supports subsea applications and meets the pending release of the Energy Institute  AVIFF subsea guidelines
  •  Pipe material and library
  •  Project archiving and document control
  •  Team-based access for better collaboration
  • Nexus IC integration and LOF syncing
  • Links to anomaly management module (Veridian AM)
    Easily identify and evaluate all potential excitation mechanisms

Why screen for vibration risks?

Industry research confirms that vibration-induced fatigue failures are a major source of fluid release in hydrocarbon facilities1. These failures are costly in terms of safety, environmental damage, corporate liability, extended downtime and financial losses.

API integrity management standards (API 570,571, 574 and 584) consider vibration as an important damage mechanism that requires proactive management for all small-bore connections (SBCs) and piping.

2019 new features and improvements

New features and improvements in Veridian 1.3 include:

Void fractions are only used if you select the EI Guidelines 2020 (which is not yet available).

  • Linked vibration screening and anomaly management modules
    You can now link vibration screening assessments to an anomaly in Veridian AM
  • AIV improvements and more save options for AIV models
    • Add comments to each save (visible in revision history) or lock a model to prevent further edits
    • Enter a value for a low noise trim on a PSV or source
    • Notes field on items
    • Improved copy/paste
    • Menu bar clean-up
    • Improved scrolling through results

  • Nexus integration – sync LOFs to Nexus Integrity Centre
  • Void fraction for vibration screening
    You can now enter either phase or a void fraction in the VS Streams section. If you enter dry gas/wet gas/multiphase/liquid it will guess the void fraction.
    • Gas has now been changed to “wet gas” with a void fraction of 0.96.
    • Multiphase assumes a void fraction of 0.80
    • Liquid assumes a void fraction of 0.02
    • Dry gas assumes a void fraction of 0.99
  • New bulk import options and spreadsheet for anomaly manager
    The bulk importer now makes it much easier to enter multi-dimensional data, and you can import anomalies, surveys, measurements and recommendations separately. Talk to us to find out more about this.
