The Green Volt project is pleased to share that earlier this month, we completed our seismic ground surveys at the St Fergus South landfall site, located just north of Peterhead. This marks a key milestone in preparing for the installation of our offshore export cables using Horizontal Directional Drilling (HDD).
What is a Seismic survey?
It’s a non-intrusive method for understanding what lies beneath the surface of the ground at a given inspection site. By discharging blank charges into the ground, we generate seismic waves that reflect off subsurface layers. These echoes help us map out soil conditions, rock types, and any geological features that could impact future work associated with drilling. It’s a crucial step in designing a safe, efficient HDD route – long before the first drill bit hits the ground.
Why Do We Conduct Seismic Surveys for HDD Cable Installation?
Understanding the geology beneath the landfall point is vital to:
- Design a safe and efficient drill path for the cable
- Avoid hard rock or unstable ground
- Protect sensitive environments by reducing the need for open excavation
These surveys ensure our approach is both technically sound and environmentally responsible, aligning with Green Volt’s commitment to sustainability and best practice in engineering.
