Core Capabilities

Delivering data for critical infrastructure.

Bathymetry Survey

A bathymetric survey is the process of mapping the seafloor.

Geophysical Survey

Geophysical surveys are a vital tool for locating and mapping objects and features buried underground or underwater without the need for excavation.

Offshore Platform Site & Pipeline Route Surveys

Offshore platform and pipeline surveys are critical for the planning, design, and safe installation of subsea infrastructure.

Submarine Cable Route Surveys

Submarine cable route surveys are essential for the successful deployment and long-term operation of underwater communication and power cables.

Topographic Survey

A topographic survey is a detailed map of the physical features of a piece of land.

Gradiometer Surveys for UXO Search

Gradiometer surveys are a vital geophysical technique used to detect Unexploded Ordnance (UXO).

Shallow & Deep Water Oceanography

Shallow Water Oceanography, also known as coastal oceanography, focuses on the ocean environment from the shoreline to the edge of the continental shelf, typically to a depth of about 200 meters.

Weather Forecasting Services

Weather forecasting services use a combination of science, technology, and observation to predict the state of the atmosphere at a future time.

Wide Area Positioning Services

Wide Area Positioning Services (WAPS) are a type of augmentation system that provides improved accuracy for standard satellite navigation systems.
