Geotechnical Survey

Overview

Enviros investigates ground conditions offshore, nearshore and on land. Borehole samples show which materials lie beneath a site, while field and laboratory tests establish how their properties change with depth. These findings provide engineers with essential ground information to support informed decisions during project planning, design and installation.

Our Geotechnical Survey Services

The type of structure, expected loads and proposed installation method guide where to investigate, how deep to sample and which soil properties to test.

Drilling & Soil Sampling

Recover soil samples at selected depths to identify the materials beneath a site.

In Situ Testing

Measure changes in soil resistance with depth using cone penetration testing (CPT).

Laboratory Soil Testing

Classify recovered samples and measure soil strength and compressibility.

Cable & Pipeline Burial Assessment

Identify soil conditions along a proposed route that may affect trenching and burial.

Our Approach

Investigation Planning

Review the proposed layout and available survey data to select test locations, sampling depths and equipment.

Field Data Collection

Drill boreholes, recover samples and carry out in situ tests to record ground conditions at each location.

Data Processing & Analysis

Compare laboratory results with field measurements to identify soil layers and determine the properties relevant to design.

Findings & Reporting

Present soil profiles, test results and engineering parameters, highlighting ground conditions that may affect construction or installation.

What We Use

Geotechnical drilling rigs recover soil samples from beneath the seabed, while cone penetration testing systems measure how soil resistance changes with depth. A central moonpool provides access for drilling and testing, and an onboard laboratory supports initial soil analysis.
