Generally composed of recent sediments, which can include highly plastic soft clays (e.g., West Africa), carbonate sediments (Australia), or highly overconsolidated clays and dense sands (North Sea).
Geotechnical engineers also design the interactions between subsea pipelines/cables and the seabed. Offshore Geotechnical Engineering
Inverted bucket foundations that use suction to embed into the seabed, ideal for floating structures. Generally composed of recent sediments, which can include
Initial data gathering using bathymetry (echo sounder), side-scan sonar, and seismic profiling to map seabed features. Geotechnical Investigation (Drilling & Sampling): Generally composed of recent sediments
Used for fixed steel platforms (jackets) and monopiles for wind turbines, driven into the soil to transfer loads to deeper strata.
