Geomeasure

Introduction

Offshore wind energy is a renewable source of energy that is constructed increasingly in the future. Baltic Sea sediments mostly consist of soft thick layers of clay though the seabed construction conditions are largely unknown. Project Geomeasure – Foundations for green offshore energy production in Finland: from marine investigations to the numerical estimation of undrained shear strength of the seabed deposit layers under cyclic loading investigates geological and geotechnical properties of the seabed in the Baltic Sea focusing to the variation of undrained shear strength in different deposition environments. Undrained shear strength is measured by Free Fall Cone Penetrometer (FF-CPT) and the results are compared to results from samples analysed in the laboratory including, e.g., triaxial tests among others. In addition, the project includes numerical modelling of static and cyclic loading due to wind, wave and ice actions that cause decrease of strength in the sediment.

This project has received funding from the European Union – NextGenerationEU instrument and is funded by the Academy of Finland under grant number 347603.
