Vibration Xodus Group engineers produce robust engineered solutions before expensive failures occur. Vibration induced failures in process systems can cause major safety, reliability and operational problems. The Vibration Engineering service from Xodus aims to prevent these failures. Using a combination of physical measurement, analysis and modelling tools to identify vibration and fatigue problems, our engineers help our clients meet exact design requirements and avoid problems arising, or solve any that arise during design, construction, commissioning and operational phases Our experts support safety and asset management strategies from the initial stages of plant design through to final plant life extension programmes and we have been closely involved with the development of risk-based assessment methodologies, including the industry-standard Energy Institute Guidelines. Expertise and technologyDuring the design phase we use our knowledge of field operating conditions together with modelling of dynamic systems to quantify the fatigue threat posed by dynamic response. We then assess the effect of potential process and / or structural modifications to ultimately eliminate potential vibration related problems before construction starts. Our structural and pipework vibration engineering team offers vibration risk assessments on existing assets, using industry-standard vibration criteria combined with site visits to identify at-risk components. In field measurement, we provide a range of instrumentation and data logging solutions to record, characterise and understand intermittent problems or long-term plant performance issues. Our engineers can also help train clients’ staff so that they gain an understanding of vibration threats to help strengthen internal asset management skills. Project experienceOur experience encompasses offshore, including topsides and subsea, and onshore gas treatment, Liquefied Natural Gas (LNG) and refining facilities in Europe, North America, the Middle East, Asia and Australasia.
