Survey specialist EGS said it has just completed two geotechnical campaigns for international offshore wind farm developers in Taiwan.
EGS mobilized a DP2 vessel with a purpose-built 40 tons SWL heave compensated deployment system over the centerline moonpool for a 200kN seabed CPT unit.
The geotechnical campaign acquired in excess of 4000m of deep seabed CPT data to depths in excess of 40m bsb, and around 700m of vibrocore samples.
Laboratory testing of soil samples and final processing of CPT data were done onboard the vessel.
In addition, EGS said it deployed the world’s first combined Thermal Conductivity and CPT system. The system provided valuable in-situ and real-time thermal conductivity data along the inter-array and export cables enabling cable engineers to work from a robust dataset to reduce manufacturing and installation costs of the power cables.
The company is now preparing for the next survey season by strengthening its core geotechnical team as well as developing new technical solutions and final digital products.
