  1. Cable Route Surveys: Our highly skilled and experienced team specializes in conducting offshore cable route surveys for offshore wind farm projects. We utilize advanced seabed and vibrocore technology and equipment to assess the shallow soil conditions, identify thermal properties, and ensure the optimal placement of power cables. Our comprehensive surveys consider environmental factors while maintaining adherence to industry standards and regulations.

  2. HDD Cable landfalls: We have experience on the East Coast of the US with drilling deeper borings and conducting combination drilling & CPT to evaluate 30-40m of seabed soils for HDD landing sites.

  3. Offshore and Onshore Substations: Our company specializes in the geotechnical investigations for both offshore and onshore substations focusing on the unique requirements of offshore wind farm projects. Our team of experts collaborates closely with clients to develop customized solutions that integrate the latest technologies and industry best practices to deliver the best geotechnical site investigation.

  4. Transmission Upgrades: Gregg Drilling is poised at the forefront of transmission upgrades, offering innovative solutions to access difficult sites via heliportable equipment or steel track off-road capable drill rigs.
