Introduction
The Berwick Bank project aims to install 4.1 GW of offshore wind capacity in the North Sea off the coast of Dundee, Scotland within an area of 1,010 km2. Over a two‑year engagement (2024–2025), GeoIntel has supported Phase A by overseeing the geotechnical laboratory campaign, delivering a comprehensive laboratory testing strategy report and providing the input parameters for advanced laboratory testing.

Laboratory Program Review & Audit
GeoIntel joined during Phase A to critically review existing documentation, including laboratory test method statements. We provided detailed comments to confirm that selected test methods aligned with the site’s unique soil conditions. Shortly thereafter, we conducted on‑site audits of UK laboratories to verify best practices and, where required, specified procedural enhancements. These enhancements introduced more advanced test methods that yielded higher‑quality, in situ‑representative data and significantly reduced sample damage during preparation. In parallel, we provided the input parameters for advanced laboratory testing and offered practical recommendations for site investigation protocols to improve sample preservation and transport. Together, these measures ensured accurate site characterization and delivered the parameters essential for foundation design.
Data Interpretation & Testing Strategy
Our team reprocessed and interpreted raw high‑pressure dilatometer (HPD) data alongside cone penetration test (CPT) profiles. Integrating these findings with previous laboratory results, we derived the most representative design profiles for overconsolidation ratio (OCR) and lateral earth pressure at rest (K₀), leveraging both commercial and in‑house software tools. Following completion of these analyses, we authored a ‘Laboratory Testing Strategy Report’. This document delineates required test types, their objectives, and the derivation methods for boundary conditions. Where advanced testing was needed, we provided full method statements. The report unified the project team’s approach across all phases, ensuring consistency and alignment.
Tender Document Preparation for Phase B
In preparation for Phase B, GeoIntel performed an exhaustive review of the scope of work and site investigation plans, proposing refinements to maximize both the volume and quality of collected data. We assessed and enhanced the technical specifications for in situ measurements and sample recovery to guarantee robust field performance. Our team then developed detailed technical specifications for laboratory testing procedures and defined laboratory operational requirements to uphold rigorous quality standards. Finally, we compiled a comprehensive bill of quantities tailored for the tendering process, ensuring clear cost definitions and facilitating competitive bidding.
Client Commendation
Working on the Berwick Bank project has been immensely rewarding for everyone at GeoIntel. The collaboration with the project team and contractors has not only challenged us technically but has also fostered a shared commitment to excellence. As the package manager remarked, “We sincerely appreciate your expert input into the project and your involvement has certainly raised the standards within our team and improved our contractor delivery.”
