- ADVACT can provide complete and detailed field exploration work including the geological structure and layer details and geotechnical soil properties at the proposed off-shore sites, utilizing ample knowledge and experience of in-house engineers and technicians who specialize in soil mechanics and foundation engineering.
Seabed-seated Cone Penetration Tests
- For the optimum design of off-shore foundations, ADVACT utilizes a special cone penetrometer that sits on top of the seafloor surface. This is one and only such type of cone penetrometer available in Korea and capable of obtaining complete and highly reliable details on geotechnical data even at mid- to deep water locations.
Advantages of the Seabed-seated CPT
- Detailed geotechnical investigation of the seafloor at mid- to deep water locations
- Cost effective, specially at deep water locations
- Can increase the penetration thrust using a suction pile as penetrometer casing
