GEOxyz has responded to the growing demands of its clients, for integrated geophysical and geological data acquisition. GEOxyz operates its own suite of geotechnical coring and sampling equipment. Seabed and subsoil sampling provides geological samples required for geotechnical testing for engineering design as well as to ground truth geophysical survey results. Soil sampling also provides material for geochemical analysis for both exploration and environmental purposes. GEOxyz successfully operates a number of seabed sampling and coring systems for shallow soil sampling. For deeper engineering we can provide geotechnical boreholes and deep CPT via a partner company DP2 drillship.
Cone Penetration Testing (CPT) determines sub-surface stratigraphy and characterizes the materials present. It provides geotechnical parameters and data for direct geotechnical engineering and design.
GEOxyz provides a range of marine seabed CPT's to deploy from our own vessels, from 50kN to 200kN and up to 40m sub seabed asset operators and have extensive experience in the hydrocarbons and renewables sectors. we also provide CPT and Composite deep push boreholes trough partner companies with dedicated geotechnical drillships.

GEOxyz uses a piston corer to take samples from soft, cohesive soils. Penetration of the sea-floor is achieved by gravity only. With a purpose-built trigger mechanism, the actual distance of free fall towards the seafloor can be adjusted.
GEOxyz box corers are designed to take undisturbed samples from the top layer of the seafloor.
These can be used for most types of sediment.
Operating the standard box corer is relatively straightforward. When the frame reaches the seafloor, a weight is taken off the hoist cable and the trigger mechanism releases the Cylinder-shaped core box. The box will then penetrate the seafloor to a maximum of 50 centimeters as a result of its own weight.
A full geotechnical examination includes surface and subsurface exploration, soil sampling, and boreholes provide the information about the composition of the seabed. It is a must for an offshore construction project.
In order to conduct the report, a drilling rig or hand operated augers will be used to extract soil samples that are sent to a geotechnical service testing lab to be analyzed.
GEOxyz provides a basic range of offshore testing, complemented by an onshore soils laboratory providing the full suite of geotechnical engineering testing and reporting. Our partner soils laboratories are accredited to internationally recognized standards.
The samples chain of custody established by GEOxyz guarantees the maintenance of the necessary conservation conditions for each sample type until its arrival to the laboratory.
GEOxyz data centre experts have extensive expertise in geotechnical data processing, data analysis and reporting, we guarantee a timely and thorough analysis of your data. In addition to the delivery of a concise and clear report, we can provide information during the commercial and operational phases of a project.
