Proven solutions that safely deliver reliable and accurate data
Our broad marine survey capabilities are based on a trusted combination of new and time-tested technology and processes. With over 30 years experience as a leading geotechnical contractor, we have a proven track of capturing reliable and responsible data, ensuring our clients have the best information to carry out their projects. Unique to CMS GeoScience is our ability to provide a high level of survey support, meaning that our dynamic team and bespoke equipment is available for global deployment exactly when our clients need it.

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.
