Geotech & Marine Construction
from Land to Sea
The implementation of expansive offshore wind initiatives on a global scale represents the most significant shift in energy production in generations.
Seas Geosciences was created to support this clean-energy expansion – and more – by integrating decades of specialized expertise in geotechnical solutions and marine construction.
Understanding the nature and mechanics of soil is one of the most critical elements of offshore development. Geotechnical and geophysical site characterization for foundations, mooring and cable routes are the first and most important priority for every project.
An increasing number of projects will be approved in more remote and difficult locations, using both floating and fixed technology. Our innovations and experience are geared towards addressing unique challenges such as environmental restrictions, marine life preservation, challenging bathymetries and soils, and deeper waters.

Geophysical

We specialize in providing comprehensive geological and geophysical solutions for both onshore and offshore projects. With a rich history and expertise in the field, our company offers a wide range of testing services to clients across various industries.
Our onshore geophysical testing services use a variety of methods to assess subsurface conditions. We employ cutting-edge technologies and advanced equipment to conduct seismic surveys, electromagnetic surveys, ground penetrating radar (GPR), resistivity surveys, and more. These services help our clients gain valuable insights into geological structures, identify potential hazards and optimize resource exploration.
For offshore projects, our company excels in providing geophysical testing services specifically tailored for the marine environment. We utilize state-of-the-art marine geophysical surveying techniques, such as multibeam and sidescan sonar, sub-bottom profiling, magnetometry, and bathymetry, to map and characterize the seafloor and sub-seafloor conditions. Our offshore services assist clients in locating valuable resources, planning and engineering offshore structures, and assessing potential risks and environmental impacts.
We continuously invest in research and development, ensuring we stay at the forefront of technological advancements in the field of geophysics.
