Subadra was commissioned to deliver a 120 metre deep borehole in North Yorkshire to support the installation of a new cathodic protection anode. The works formed part of a wider programme to protect critical buried infrastructure across the region.

The Challenge

The borehole was advanced through coal measures geology, a complex and potentially hazardous environment due to the presence of residual gases and combustible material. These conditions required careful planning and control measures to ensure safe drilling and to prevent ignition risks underground.

The Solution

Our drilling specialists employed a water flush system to suppress sparks and maintain stability during the drilling process. Continuous water circulation enabled precise monitoring of drilling parameters and groundwater conditions, ensuring that works were completed safely and efficiently.

The Outcome

The installation was successfully completed to specification, providing a durable anode system that will help extend the lifespan of key energy infrastructure assets across northern England.
As the final checks were completed, a rainbow appeared over the site, a fitting end to a technically challenging project completed safely and successfully.
