Site investigation systems


Ashtead Technology have an extensive array of packaged solutions covering a range of site investigation applications.

Knowing what is on and under the seabed is vital for planning cable installation routes and structure foundations. It’s essential that all seabed and subsurface hazards are accurately and reliably identified as this information will be used to plan mitigation and avoidance measures. Of equal importance is the composition of seabed soil, to ensure construction assets can operate safely and loaded structure foundations remain stable throughout the asset lifecycle.

We have extensive experience in the optimisation and integration of vessel mounted, towed and ROV deployed equipment solutions including sonars for bathymetric, side-scan, sub-bottom and swath surveys, magnetometers, pipeline/umbilical detection systems and geotechnical equipment. As specialists in providing multi-sensor multiplexed data solutions, we can integrate many sensors over a single optical fibre or copper link allowing sophisticated applications to be rapidly and reliably configured.

As part of our service, we offer technical advice, system integration and mobilisation along with trained and experienced offshore technicians to operate, collect data and maintain the systems throughout the survey project.
