Desktop studies

With significant geological experience we tailor the desktop study to follow your requirements. We offer to build a local stratigraphic framework for a specific site on the basis of available data and published regional studies. This includes a review of all relevant background information such as seismic data, logs, geotechnical data, bathymetry as well as risk assessments regarding geo hazards such as peat, boulders, active and inactive gas- and oil fields, shallow gas and existing pipelines. We will evaluate the quality of available data and offer recommendations for further data acquisition and analysis. The aim of the desktop study is to pinpoint relevant key features and obstacles of the subsurface as a primer for planning seismic and geotechnical surveys.

Ground modelling

The ground model integrates geotechnical and geophysical data in a 3D model. We apply a geological approach with focus on knowledge of the basin setting when integrating data. This results in a coherent ground model that is based on units and properties that are in compliance with the general geological understanding of the area. The resulting ground model will efficiently capture 3D distribution of geotechnical properties relevant for design and planning of installations as well as an assessment of geo-hazards.

Foundation design

From the measured and inferred geotechnical properties, we can design wind turbine and support infrastructure foundations such as transformer platforms, energy islands and jack-ups. We have implemented parametric workflows for axial pile capacity analysis, lateral pile response analysis, shallow foundation capacity, suction caisson installation behavior and pile drivability. Depending on the project stage, we offer to either determine indicative dimensions of several foundation options (to provide input for foundation cost models) or provide a detailed design for all locations in a wind farm. Sensitivity studies can be conducted to determine which geological units or soil parameters lead to the greatest uncertainty on the geotechnical foundation behavior. Based on the outcome, we will evaluate if additional geotechnical characterization is recommended in order to further de-risk your project.
