The State-of-the-Art of Marine Risers and Pipelines

Dear Colleagues,

Marine risers and pipelines are critical components in marine resource utilization, transporting oil, gas, natural gas hydrate or mineral particles. Risers connect the subsea wellhead or manifold to the surface platform, experiencing the combined action of internal conveyed fluids and external wave and current. Subsea pipelines laid on uneven seafloor undergo a complicated soil–pipe interaction. In addition, the suspended pipe spans subjected to sheared current possibly bear the vortex-induced vibration as well as the pipe–seabed collision. Moreover, the boundary constraints affect the dynamic behavior of marine risers and pipelines. The associated factors include the movement of the platform, the configuration of the riser, the arrangement of buoyancy modules, the pipe–seabed gap, etc. Due to the potential fatigue damage caused by flow-induced vibration, a further understanding of marine risers and pipelines in such complicated conditions is important in predicting service life and conducting operation optimism. Extensive investigations into this topic have been carried out. Therefore, this Special Issue focuses on the state of the art of marine risers and pipelines. We seek contributions from authors that include, but are not limited to, the following areas:

(1) Multiphase flow-induced vibration of marine risers;

(2) Vortex-induced vibration of risers;

(3) Multiphase flow-induced vibration of marine pipelines;

(4) Vortex-induced vibration of pipelines;

(5) Soil–pipeline interaction;

(6) Flow control and vibration suppression of risers and pipelines;

(7) Hydrodynamic analysis;

(8) Fatigue life prediction;

(9) Optimize layout of risers;

(10) Intelligent monitoring and maintenance.
