Abstract: In drilling from floating vessels, most operators and drilling contractors specify an allowable lower ball joint angle of 3–5 deg for drilling and 1–3 deg for running casing. Presently, no one ...

Abstract: The two-dimensional dynamics of an oil containment barrier, which was designed to have very low tensile loads due to current and waves, were simulated with a theoretical model. The model was ...

Abstract: This paper describes testing and analysis which demonstrates that collapse specimens tested in short testers with rigid end seals give artificially high collapse values. It also compares the API ...

Abstract: This paper describes a computer program for economically predicting the dynamic response of marine risers to lateral forces from waves (regular and random) and currents (vortex shedding). Present ...
