... preventer (BOP) and conductor system natural frequency and result in fatigue damage accumulation in the conductor system below the mudline. A substantial consumption of the conductor system fatigue capacity as a consequence of VIV during drilling operations may leave insufficient fatigue margin...

... that the internal casing strings do not cause buckling of the integrated system. By utilization of these design methods the conductor system will become more slender compared with previous designs and thereby more vulnerable to dynamic excitations. The dynamic behaviour of the well conductor can be divided into two...
