Abstract
Summary
The design and installation of offshore infrastructure such as WTG foundations requires a sound knowledge of the geological character of the sub-seafloor. The layout changes undertaken after the geotechnical campaign require the assessment of the geotechnical properties on not directly investigated locations within the windfarm area. In this study, we developed a flow to interpolate the quantitative interpretation from the 1D geotechnical data into a 3D volume. We apply synthetic seismograms calculated from available and interpolated geotechnical information and seismic wavelet derived from the seismic data to quantify the interpolation quality.
