Abstract
The reinstallation of jack-up rigs near an existing footprint has been identified as one of the key challenges in the offshore oil and gas industry. This study introduces the effect of spudcan shapes to minimise spudcan-footprint interaction. A series of 3D large-deformation finite-element (LDFE) analyses and centrifuge tests have been carried out varying combination of spudcan shape factors: (a) underside profile; (b) skirt length; and (c) number of holes. The results from this study indicate that subtle changes in spudcan shape can ease the spudcan-footprint interaction issues.
