Initial data gathering using bathymetry (echo sounder), side-scan sonar, and seismic profiling to map seabed features. Geotechnical Investigation (Drilling & Sampling):
Potential hazards include landslides, mudslides, pockmarks, and liquefaction. 2. Offshore Site Investigation (SI) Offshore Geotechnical Engineering
Foundation design is tailored to the structure type and water depth. and liquefaction. 2.
Offshore geotechnical engineering is a specialized branch of civil engineering concerned with the behavior of seabed soils and the design, construction, and maintenance of foundations for human-made structures in the marine environment. It plays a critical role in the oil and gas sector and is essential for the rapid expansion of offshore wind farms. 1. The Marine Environment and Soil Behavior Offshore Geotechnical Engineering
Geotechnical engineers also design the interactions between subsea pipelines/cables and the seabed.
Drag anchors and vertical load anchors designed to secure floating oil/gas platforms and floating wind turbines. 4. Pipeline and Cable Geotechnics
Utilizing in-situ testing tools like Piezocone Penetration Testing (CPTU) directly from the seabed.
