Vibration control of a viscoelastic flexible marine riser with vessel dynamics
Mathematical Modelling and Analysis, 2018 In this work, we investigate the asymptotic behavior of solutions of a viscoelastic flexible marine riser with vessel dynamics. Under a suitable control applied at the top end of the riser, we establish explicit decay rates for a large class of ...

Distributed Fiber Optic Sensing for Real-Time Monitoring of Gas in Riser during Offshore Drilling
Sensors, 2020 Effective well control depends on the drilling teams’ knowledge of wellbore flow dynamics and their ability to predict and control influx. Unfortunately, detection of a gas influx in an offshore environment is particularly challenging, and there ...
