Site investigation survey systems

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

Ashtead Technology have extensive knowledge and experience in the selection, application and integration of all types of hydrographic, geophysical and geotechnical sensor systems and can engineer solutions, which deliver maximum commercial and technical benefits.

Site investigation involves many aspects of data collection requiring the integration of data from multiple diverse sensors to deliver accurate results.

Understanding how to integrate sensors, whilst maximising the speed of data collection is critical to any site investigation. This approach delivers significant cost reductions, minimal vessel time, and high quality results.

Integrated solutions

Discover how Ashtead Technology incorporates market-leading technologies and innovative life of field services to help clients deliver complex projects.

As a market-leading supplier of subsea equipment, we have a firm understanding of advanced hydrographic sensors, and how they can be adapted to meet the requirements of a wide range of survey platforms. We can ensure maximum performance from equipment and data acquisition systems, eliminating downtime and increasing survey efficiency.

The integration of critical data with a survey platform is a key issue that is often misunderstood or overlooked and if not managed properly, it can result in low quality results, increased time and cost.

By delivering a complete one-stop-shop, from the supply of sensor systems to the provision of trained and qualified offshore technicians, we can support your hydrographic system integration applications.

Our expert team has an established and proven track record in providing integrated geophysical survey packages and support services to our clients across the globe. We have the knowledge and experience to ensure every survey project works as a system, delivering the highest quality data with reduced vessel time.

Identifying and quantifying subsurface geo-hazards is a vital task which requires a high level of care as the consequences of missing important information such as shallow gas or unstable foundations can be critical.

We can support you in selecting the correct sensor suite including shallow seismic, low frequency acoustic profiling systems and magnetometers integrated with deployment, data collection and processing systems on a range of towed and powered survey platforms.

Geotechnical information is an essential component in the engineering of structure foundations, assessment of jack-up rig stability, pipeline engineering and deciding upon flowline, umbilical and cable installation methods.

Along with taking physical samples, information on how, where and to what depth and orientation the sample information has been taken is crucial. This helps to simplify and reduce the cost of deploying sampling and sensing systems.

At Ashtead Technology, we can deliver significant cost savings to clients and add value through the integration of sensors, sampling systems, and complete geotechnical suites, which can be deployed by winch, ROV or vessel.

Proud to add value to every project, we apply our in-depth knowledge to determine which sensors to use and how to deploy and integrate systems, without cross-interference. We can package and integrate systems on to a range of towed and ROV platforms, ensuring instrument cross-compatibility whilst removing the risk of data corruption and down time.

Seabed and subsurface hazards present challenges that need to be overcome. This requires potential issues to be located and identified using sophisticated remote sensing techniques and multiple sensitive sensor technologies.

Unexploded ordnance presents additional specific hazards which have to be either removed or avoided during subsea installation.

Included in our capability is the provision of highly competent and trained offshore support services, providing system integration and dedicated technical support throughout the operation.
