ABSTRACT
The seismic cone penetration test (SCPT) is one of the most frequently used in situ testing methods for deriving the small strain shear modulus. Offshore SCPT results often present large scatter, in particular when data are obtained with different operational setups. No standard or industry consensus exist in terms of requirements to system key characteristics, operational testing procedures, interpretation and the numerical quality control of the traces obtained. Seismic sources currently deployed as part of the offshore industry practice have been developed individually by the various suppliers. This paper presents the findings of an onshore experimental study with the objective to increase the understanding of the influence of the offshore seismic source setup on SCPT results under controlled operational procedures. Accuracy and precision of the SCPT are investigated as part of the study.
