To investigate the effect of a multiphase internal flow with hydrate phase transition on the
vortex-induced vibration (VIV) of a marine riser, a numerical model is established that first …

A path integration method is used to discuss the stochastic response of a marine riser
excited parametrically and externally by correlated Gaussian white noises. On the basis of …

Natural gas hydrate (NGH) is a kind of clean energy which has attracted more and more
attention. At present, deepwater drilling engineering is an effective way to develop the NGH …

When the surface casing hole section is accomplished, the surface casing will be installed
into the hole by the landing string for cementing operation in deepwater drilling. During this …

Marine risers are the main transportation channels of offshore oil and gas from the
wellheads to the floating platforms. In mixed oil and gas transportation, natural gas hydrates …

In order to study the dynamic response of a drill pipe under the motion of the float platform,
