CMS GeoScience
Leading the way in geotechnical marine 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.
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.
Geophysical Site Investigation
Our comprehensive suite of solutions for geophysical and hydrographic surveys and site investigations comes from decades of in-house expertise. We integrate a vast range of state-of-the-art technology to deliver precise geophysical information to de-risk, minimise delays and reduce costs in the design and engineering of your project.
Benthic & Environmental
We own, operate and hire an extensive range of benthic and environmental equipment. This includes the Hamon Grab, Mini Hamon Grab, Single Day Grab, Double Day Grab, Single Van Veen Grab, Double Van Veen Grab, Beam Trawl, Box Corer, and Hydraulic Clam Shell. All are available to support and enhance your marine projects.
Core Analysis & Storage
We partner with accredited labs for MMO and Marine Scotland certified testing, delivering comprehensive analysis for your marine projects. Our secure, on-site core storage, controlled for temperature and humidity, safeguards samples and facilitates efficient access for current and future analysis.
Vessel Charter
Our 24m proven multi-purpose, versatile survey vessel, MV FlatHolm, is certified by the UK Maritime & Coastguard Authority to work up to 60nm offshore, providing accommodation for 12 persons including a crew of four. She is available for crewed charter as is or can be supplied with qualified surveyors to carry out works around the UK, Ireland and Europe.
Equipment Rentals
We provide a comprehensive range of geotechnical equipment for hire. All our equipment is routinely serviced, well-maintained and fully certified for operational use. Before each rental, our equipment undergoes thorough checks to guarantee safety, reliability, and optimal performance on your site.
Our Projects

CMS GeoScience successfully carried out site investigation surveys for RWE Renewables UK at their proposed offshore wind farm site on Bray Bank and Kish Bank off the coast of Dublin, Ireland.
We performed a suite of geotechnical tests to gather data to inform the development of the site.
When complete, the Dublin Array will comprise of between 39 and 50 wind turbines, power over 770,000 Irish homes and reduce Ireland’s carbon emissions by ~1.5 million tonnes annually.
CMS GeoScience completed the project on time, meeting all the key milestones and avoided any health & safety issues and technical downtime.

CMS GeoScience partnered with the Blue Marine Foundation, the University of Exeter and Jersey Marine Resources on The Convex Seascape Survey.
This exciting initiative is a pioneering collaboration of world-leading scientists, working to quantify and understand blue carbon stored in the coastal ocean floor and the effects of marine life upon it.
The role of our specialised geotechnical team was to collect 55 vibrocores and 8 multicores across various locations in the waters around Jersey.
Demanding environmental, geological and weather factors presented a specific challenge to the team, with rocky outcrops exposed by the high tidal range. Extensive planning using tidal and weather forecasts, as well as water depths, enabled the team to maximise working windows and complete work safely.
We are proud to have played our part in helping researchers highlight the need to preserve integral marine habitats.
The Convex Seascape Survey

CMS GeoScience operates far and wide, but this was a great opportunity to work on an exciting maritime development much closer to home here in Falmouth.
Working in conjunction with A&P Falmouth, part of the APCL Group, and Geotechnical Engineering Ltd, CMS GeoScience carried out a successful geotechnical survey within Falmouth Docks as part of the initial stages of a regeneration project. Our experienced geotechnical team were able to collect 26 vibrocores for archaeological and MMO analysis.
The challenges associated with this project were demanding but proved to be an opportunity to put our robust and proven geotechnical systems to the test, resulting in a productive campaign for all involved.
