Good (and bad) Vibrations: Designing for Flow Induced Vibration with Simulation
Tuesday, February 16, 2016

Flow Induced Vibration (FIV) is a design concern for piping networks, such as jumpers and manifolds. When the piping is deployed subsea, obtaining an accurate understanding of FIV is imperative, since failure and subsequent remediation is costly at best, and likely infeasible. Simple methods, such as the Energy Institute (EI) guidelines, are used to assess the likelihood of FIV. However, these are highly conservative, potentially leading to unnecessary additional costs.

In recent years CFD tools have been used to predict the multiphase flow in the pipelines, forcing on the pipe, and the resulting forcing and fatigue. This allows them to accurately quantify the fatigue life, preventing costly failures or over-design.

This educational webcast features presentations from Oil & Gas engineering and management consultants Norton Straw and CD-adapco’s Oil & Gas technical specialist Alex Graham. They outline a typical FIV study: starting with the EI guidelines, followed by CFD and FEA simulations.
