ABSTRACT

Deployment of jackups in clayey soils poses potential leg extraction challenges, which if not addressed in a planned manner, could result in additional rig move time, affect structural integrity of the unit and lead to higher spread costs due to unintended delays. Among other factors, delays in removing the legs can be attributed to the uncertain effectiveness of the typical water jetting system as well as the apparently lack of understanding on the impacts of certain leg pulling out procedures adopted in the field.
