Skirted foundations have proved to be a boon to the offshore industry on account of their cost-effectiveness and easy installation process in comparison to other offshore foundations. Skirted ring foundations are a kind of circular skirted foundations with an annular region. These foundations are inspired by shallow ring foundations that offer similar bearing capacity to circular foundations but with reduced material usage, lowering costs and carbon emissions. Their optimized design enhances load distribution while promoting sustainability through decreased concrete consumption. The present analysis uses a pseudo-static limit equilibrium approach to determine the static and seismic lateral and vertical load capacity of the skirted ring foundation in sand overlying clayey soil. A three-dimensional (3D) finite element analysis (FEA) is conducted using the ABAQUS Cae computer program to evaluate the influence of key parameters, including skirt length (L), and seismic acceleration coefficients (kh and kv), on the seismic lateral and vertical load capacity of the skirted ring foundation. An increase in length augmented both lateral and vertical capacity, whereas a higher seismic acceleration coefficient diminished their effectiveness. A detailed comparison is provided between the current results and available static and pseudo-static analyses, with an emphasis on the underlying assumptions of each method.
