Vibration-induced fatigue management (Offshore Magazine)

How web tools enable effective piping vibration management

In the field of asset integrity management, it is corrosion and erosion that attracts the lion’s share of management time, resources and analysis. The majority of plants usually have a full-time corrosion or integrity engineer whose principal responsibility is identifying, preventing or mitigating possible corrosion or erosion damage events. This is because corrosion or erosion is almost inevitable, with potentially catastrophic consequences.

In contrast, vibration and its consequences attract significantly less attention and management activity. But inadequately managing the threat of vibration can be equally catastrophic – and, in fact, accounts for a relatively high percentage of reported failures, notably in harsh environments.

However, the approach to vibration management is changing, becoming more proactive, more preventative and more global. This has been driven by three factors:

  1. Demand from operators with an international perspective
  2. Wider dissemination of existing standards and industry guidance
  3. Supply of enabling technologies that bring vibration to the heart of asset integrity management
