Large concrete or steel structures that sit on the seabed, relying on their weight to resist loads.
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). Offshore Geotechnical Engineering
Calculating penetration depths, breakout resistance, and thermal expansion effects. 5. Advanced Design Challenges and Trends Offshore Geotechnical Engineering (CVEN90071) Large concrete or steel structures that sit on
Foundation design is tailored to the structure type and water depth. carbonate sediments (Australia)
Potential hazards include landslides, mudslides, pockmarks, and liquefaction. 2. Offshore Site Investigation (SI)
Utilizing in-situ testing tools like Piezocone Penetration Testing (CPTU) directly from the seabed.
Used for fixed steel platforms (jackets) and monopiles for wind turbines, driven into the soil to transfer loads to deeper strata.
