Foundation performance of neat-supported jackup rigs in soft clays

Mat-supported jackup rigs often experience mat penetrations approaching the thickness of the mat in soft soil areas. Data obtained with an electronic bottom sensor show that actual mat penetrations differ from divers' observations because of a soil mound that forms near the mat's edge. This paper compares the mat penetration data with various bearing capacity procedures and strength data to help assess which procedure gives the most accurate prediction. It describes geologic features and soil properties that may influence the foundation performance of these rigs. The paper concludes by recommending types of geophysical and geotechnical studies to be performed to evaluate the expected foundation performance of mat-supported rigs more thoroughly.
