... pipe, unlike casing, is used repetitively under high torque applications from one rig to the next. Drill pipe connections are typically subjected to cyclical fatigue, high torsional loads, and multiple make-ups and breakouts. Most of the time, drill pipe is tested per customer requirements or per API...

... in the abovewater portion of the plat- form. With Xi denoting the average deflection of level i, the Flexibility Parameter depicted in Fig. I is defined as: X2 - X3t, '" ( 1) Xo - Xl Three such parameters, one for each direction of sway and one for torsion, are determined for each bay. The corresponding three...
