Energy
The Bałtyk I offshore wind farm is one of three projects jointly developed by Equinor and Polenergia. Together, Bałtyk I, Bałtyk II and Bałtyk III will provide up to 3 GW of installed capacity, enough to supply green energy to more than four million Polish households. Bałtyk I (at up to 1,560 MW) will be the largest offshore wind farm under construction in the Baltic Sea and a cornerstone of Poland’s energy transition. However, the project area presented significant geotechnical challenges, with highly variable and complex seabed conditions requiring careful investigation and interpretation.
RINA acted as geotechnical and geophysical integration expert, supporting the client in the execution and interpretation of the offshore site investigation campaign. Leveraging long-standing expertise in complex offshore environments, RINA applied advanced methodologies for soil characterization, data integration and ground model development, ensuring consistency across geophysical surveys, boreholes and laboratory testing through a rigorous and experience-based interpretative approach.
RINA supported Equinor throughout the geotechnical survey phase, including soil characterization and the integration of geophysical and geotechnical datasets across the wind farm area and export cable corridors. Drawing on extensive experience in the North Sea gained since the 1990s, RINA delivered a detailed and reliable assessment of the site, fully accounting for heterogeneity and geotechnical hazards. The combined interpretation of geophysical and geotechnical data enabled the identification of soil provinces and units, providing a step change in the understanding of this complex geo-environment and supporting a more targeted and robust engineering design.
