Randomized trial shows improved soil characterization using numerical CPTs in offshore sites, suggesting enhanced design confidence.
Key Points
This research aims to evaluate the effectiveness of numerical cone penetration tests (CPTs) for geotechnical soil characterization in offshore environments.
Utilized large deformation finite element analysis with an Arbitrary Lagrangian-Eulerian formulation.
Calibrated the numerical model using laboratory CPTs conducted in dense sand.
Applied the model to replicate CPT tests in the Italian offshore, examining the impact of cone size variation.
The model successfully reproduced on-site cone resistance profiles, considering local soil density variations.
Identified new parameters for soil modeling based on existing CPT data, enhancing the reliability of empirical correlations.
Demonstrated the utility of historical geotechnical data for the design of new offshore structures, facilitating knowledge transfer to renewable energy projects.
