Geophysical Surveys

Geophysical Surveys

Remote Sensing is Essential for Comprehensive Site Understanding

Accurate and timely seabed geophysical surveys are essential to the cost-effective design of marine structures and subsea installations. Benthic provides complete end-to-end support for accurate and timely geophysical surveys, including survey design, execution and data interpretation.

At Benthic, we provide complete end-to-end support for accurate and timely geophysical surveys, including survey design, execution and data interpretation. Working with our selected specialist partners, we draw on a full range of survey techniques, from multibeam bathymetry to side-scan sonar and sub-bottom profiling, depending on your project requirements. Then we support you with expert data interpretation and reporting, identifying geohazards and profiling geological features for optimal pipeline routing and the location of subsea structures.

Interpretation & Reporting

Reporting for Site Investigations to Comply with Regulations

In order to accelerate project development and reduce risk, Benthic provides a comprehensive picture of the seafloor environment. The initial site investigation requirements are met by integrating legacy geophysical data with 3D seismic data, geotechnical data, and site-specific information. As the project progresses, additional in situ data is gathered and integrated into the project plan. A final comprehensive engineering study is developed using the data of the facility studies.

Environmental Surveys

Environmental Surveys

Know Your Baseline

Environmental surveys are a key phase of any offshore development. By establishing the baseline levels of marine flora and fauna, water quality, salinity, heavy metals and other key compounds, a project can establish the right controls to protect the environment early in its life cycle. Environmental monitoring can then be conducted at desired intervals to ensure those controls are effective.

Benthic is able to supply a range of environmental services combined with the associated Factual and Interpretive Reporting, including:

  • Marine Mammal Observation
  • Benthic Survey
  • Sediment Sampling
  • Water Sampling & Testing
  • Geochemical Testing

Field Data Acquisitions

Compression Wave and Shear Wave Geophysical Data

Reflection data are gathered from survey vessels, remote vehicles and seabed systems. Areal data is gathered from vessels, towed/autonomous vehicles and seabed systems. Detailed interval data in the seabed is gathered using penetrometer/seabed source systems.

  • Multibeam
  • Magnetometer
  • Sonar
  • Towed seismic
