Assessment of seismic cone penetration tests: equipment set up, processing and interpretation workflows. Field test study
The seismic cone penetration test (SCPT) is a key in situ method for determining small strain shear modulus (Gmax), essential for optimizing offshore wind turbine foundation design. However, SCPT data from different systems often show significant scatter, which increases design uncertainty preventing optimal design. This study compares SCPT data from three contractors at two offshore sites to identify the most effective system configurations, data processing, and interpretation workflows. Results highlight the limitations of existing standards in ensuring reproducibility and consistency. Recommendations are provided to improve SCPT acquisition, data processing, and interpretation, aiming to enhance the reliability of Gmax estimations for geotechnical applications.
