... fracture in piping, support structure and at welds. There are multiple physical mechanisms through which internal flow in subsea production systems may induce a vibrating response of the structure and fatigue issues. One of these mechanisms involve multiphase flow induced excitations, where variations...

Since the model is new and prediction of the slug length is notoriously difficult, we set a modest target of predicting...
