Leading the way in marine survey and site investigations

We provide the data that informs your projects

Because of this, we take the quality of our work and the accuracy of our data very seriously. 

Right from the outset, we support our clients and ensure that our core values of safety, accuracy and integrity run through every project. 

The sectors we serve

Renewable
Energy

We offer expert geotechnical and geophysical site investigations that are critical to the renewable energy transition. Such work is central to determining seabed integrity and composition at the design stage of offshore wind farm developments.

Ports &
Harbours

Our cost-effective and efficient solutions cover structural inspections, navigational channel and underwater terrain mapping, hazard identification, water depth, and seabed soil and sediment assessment.

Environmental
Research

Partnering with leading scientists, universities and academic institutions, we bring our survey and sampling expertise to directly help research into the coastal and marine habitats that surround us.

Civil
Engineering

We have an enviable track record working with our valued clients in the marine civil engineering industry. We consistently provide reliable and accurate data that informs the foundation for their successful projects.

Our Solutions

With a proven track record ensuring the safety of our team, clients and the environments we work in, CMS GeoScience is well positioned to meet your marine site investigation needs.

Geotechnical Survey

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.
