Geophysical and Geotechnical Assessment

Geophysical and geotechnical assessments are used to collect and analyse data to better understand seabed and subsurface conditions. These surveys help engineers determine potential engineering constraints and identify safety hazards by collecting information on the nature and mechanical properties of the seabed. Geophysical and geotechnical assessments ensure project success and operational efficiency by providing valuable information during the pre-planning stage of projects while optimising engineering solutions throughout operations. Some geophysical surveys used to collect information and data include bathymetry surveys, side-scan sonar surveys, echo sounder surveys, acoustic sub-bottom profile surveys, magnetometer surveys and camera surveys. Geotechnical surveys allow companies to obtain sediment samples as well as conduct core and cone penetration testing. The risk of weather downtime during surveys can be minimised with our metocean services.
 
Intertek offers integrated geophysical and geotechnical assessments to clients in a variety of offshore industries such as renewables (e.g. wind, wave and tidal ), oil and gas, utilities (e.g. subsea cables and pipelines), water, ports and harbours  and construction (e.g. river and coastal). We provide Total Quality Assurance support throughout a project’s lifecycle from feasibility and design to operation and decommissioning.
 
Intertek provides you with geophysical and geotechnical assessments that allow you to better understand seabed and subsurface conditions around potential infrastructure locations. We help our clients determine what survey techniques are best designed to collect the data needed for their specific project. Our assessments help clients detect risks located at potential infrastructure sites prior to installation. These risks could include Unexploded Ordnance (UXO), over pressured zones, seafloor debris, shallow gas fields, mobile sediments, ship wrecks and manmade infrastructure. Geophysical and geotechnical assessments also help determine the mechanical property of the sea bed. This provides you with valuable information about the seabed including stratigraphy, strength, and hardness which allows you to better understand potential difficulties of installing infrastructure at that location.
 
Other engineering constraints our geotechnical and geophysical assessments help identify include obstructions on the seabed such as pipelines, boulders and other debris as well as bathymetric features like steep slopes. When your geotechnical and geophysical assessments are completed the data can be stored in our Geographic Information System (GIS) software  to give you a more coherent picture of the surveys and allow you to easily compare the state of the seabed prior to, during and after operations. Our advanced techniques and services maximise your understanding of the seabed and subsurface conditions to lower overall cost and reduce project risks.
