This technical session explores innovative approaches and challenges in offshore geotechnical engineering. It includes discussions on the use of finned suction piles in Brazil’s deepwater clay soils, data-driven techniques for 3D soil characterization, and skirt pile foundations in shallow waters. Additionally, it covers the roadmap for handling large diameter driven piles, experimental investigations of cyclic tensile loads, empirical correlations from offshore CPT data, and the stability prediction of submarine slopes with natural gas hydrates using machine learning.
