... Abstract Top tension plays an important role in stability of riser system. Either excessive or insufficient value of it tends to cause negative effects on risers' proper function and then pose a threat on drilling operation. But there is no unified calculation method about the setting value...

... of a flexible riser. In addition, the reduced tension loads greatly decrease installation vessel requirements. The large buoyancy system not only reduces the top tension but also decouples the motion passing from the upper section to the lower section. As a result, high compression and over-bending issues near...
