Geophysical Survey

Our geophysical survey team is highly experienced in providing geophysical services from client or UTEC vessels, using the most advanced sensors and data recording systems.

Additionally, we undertake pre-engineering surveys from high-precision autonomous underwater vehicles (AUV). As your partner, we analyze the data from carefully crafted, comprehensive reports and together we determine the safest, smartest, most environmentally friendly route for your pipeline and subsea installations. Design engineers also look to UTEC to supplement legacy or incomplete seabed and subsurface data.

As offshore installations are planned in increasingly challenging subsea environments UTEC employs a variety of marine geophysical surveying services tailored to meet client requirements. We are able to perform in both shallow and deep-water environments (1000+ meters). Our key services include Lease Hazard Risk Analysis, Hydrographic and Geophysical Surveys, Rig and Platform Site Surveys, Seabed Mapping Services, Shallow Geotechnical Survey Services, and Environmental Impact Assessment.

UTEC also offers a complete range of hydrographic survey services, including desktop studies (DTS), topographic landing surveys, shallow-water (including diver swim) surveys, IHO bathymetry, pre and post dredge, submarine cable and pipeline route surveys, covering the whole route from landing site, near shore to full ocean depths.

UTEC’s submarine telecommunication and power cable route survey expertise runs deep, from desktop study (DTS) and topographic landing to diver swim surveys, from landing, near shore to full ocean depth. We conduct cable burial assessments (BAS) down to 3000 meters water depth, employing cone penetration technology (CPT) coupled to conventional physical sampling with gravity, piston and grab sampling systems.
