Geotechnical Survey

We excel in providing CPT and vibrocore services and extracting sediment samples for geotechnical analysis. These techniques are vital for understanding sub-seafloor conditions, especially in sedimentary environments, and are essential for environmental impact assessments and marine resource studies.

Geotechnical Surveys

Geotechnical marine surveys provide essential information about the seabed before any offshore project goes ahead. Whether it’s for wind turbines, pipelines, cables, ports, infrastructure or environmental studies, our surveys reveal the type, strength, and stability of the ground below the seabed, information critical for designing safe and cost-effective foundations, avoiding hazards, and ensuring long-term stability.
