Solution

Topographical and ground-penetrating radar surveys

UTEC, Acteon’s Geo-services business line, was commissioned by SSE Renewables to undertake topographical and ground-penetrating radar surveys for the cable landfall areas of the Seagreen Windfarm (now Berwick Bank) which is being established in the Firth of Forth.

Data accuracy and efficiency to beat the clock 

The work comprised two cable landfall areas by Torness Nuclear Power Station near Dunbar covering over 310 hectares of greenfield site, over 5 km of minor roads and a 1.5 km section of the A1 which required traffic management. 

The customer stipulated an extremely tight project timeline with multiple gates for deliverables. 

Our solution

Remote sensing laser technologies accelerate schedule 

The customer needed to capture accurate data quickly to optimise the planning and design for the new land-based infrastructure required to meet the needs of the wind farm output. 

To support this requirement, we deployed a combination of aerial and ground survey techniques. UAV Lidar technologies were coupled with GPS and underground survey to capture the data as efficiently as possible; they allowed for the creation of highly accurate point clouds representing the scanned area.  

We delivered insights and analysis based on the data and reviewed any subsequent assumptions. Our experienced personnel stayed fully engaged through the project cycle, improving understanding as the project progressed and reducing risk and expenditure throughout the operations. 

Innovations in action 

Using the latest UAV LIDAR technologies significantly reduced the time on site for this project. The UAV Survey provided aerial photographs of the site and a LIDAR point cloud of the ground surface. This was combined with survey data captured by Total Station and GPS sensors as well as the underground data set supplied by Ground Penetrating Radar (GPR) and Radio Detection techniques.

The result 

We delivered a plethora of data, on schedule. These insights were used by the customer to optimise the planning and design of cable-landfall infrastructure, crucial to the development of the offshore wind farm.

We are pleased to be working with UTEC, a local supplier. The combination of aerial and ground survey techniques will provide the Berwick Bank Wind Farm Project team with a wealth of data that will be used for optimising the planning and design for the new land-based infrastructure required to meet the needs of the wind farm output.
