Swift and seamless geotechnical solutions for Germany’s offshore windfarm

UTEC, Acteon’s Geo-services business line, was contracted by TotalEnergies to deliver a comprehensive geotechnical site investigation in support of the wind farm development. The scope included shallow cone penetration testing (CPT), vibrocore sampling, and onboard laboratory testing across multiple locations. 

To meet the compressed schedule, the vessel M/V Vina was sourced, inspected, and approved for operations in less than two weeks, followed by successful mobilisation in just over two days. This included seabed equipment wet testing and a customer inspection. 

The survey was carried out using the Roson 100kN seabed CPT system and VKG-6 vibrocores. Lab testing onboard the vessel provided key soil data, such as thermal conductivity and electric resistivity, enabling early-stage design insights while reducing the need for immediate onshore testing. Target penetration depths and sample recoveries were achieved at every test site, allowing TotalEnergies to advance their development plans without delay. 

The project demonstrated the value of combining rapid mobilisation with integrated offshore testing capabilities. Our ability to conduct CPTs, sampling, and laboratory tests directly onboard the M/V Vina accelerated data delivery while maintaining high HSE standards. Efficient planning and execution reduced total time offshore, minimising fuel use and lowering the project’s environmental impact.
