The performance of spudcan foundations for jack-up platforms in intermediate soils is evaluated with a combination of experimental and numerical techniques. Given the possibility for these foundations to experience variable periods of load hold, attention is drawn to the effects of consolidation on spudcan installation and subsequently its combined capacity under multi-directional loading. The implementation of a hypoplastic constitutive model for structured clays underpins the numerical analyses, with outcomes validated by an extensive geotechnical centrifuge testing campaign. The results reveal a general increase in the spudcan mono and multi-directional capacity, due to strengthening and stiffening of the soil.
