... Improving the accuracy of oil and gas well design is critical to reducing the risk of structural failure over the well's life cycle, particularly for production and injection column components. The friction effect resists tubing movement and results in a redistribution of axial loads. This work...

... is the estimated conductor axial displacement; u e and u p denote the axial displacement of the conductor under purely elastic and purely plastic (i.e., the conductor approaches failing axially), respectively; P c is the axial load on the conductor; A is the cross-section area of the conductor; E...

The FPSO motion performance is calibrated by offshore field measurements and improved RAOs for the global analysis are provided based on the measured motions. Finally, the allowable axial load from the local analysis...

... straight and subject to an axial load, it does not twist or generate any torque. However, if chain is twisted while carrying axial load, or subjected to axial load when in a pre-twisted condition, it behaves in a highly non- linear manner, with the magnitude of the torque dependent upon the level of twist...
