Publication Title
Solving challenges of operational areas for renewable energy infrastructure

Abstract
The renewable energy sector requires new infrastructure for development, prefabrication, storage, installation and operation. Most often, the subsoil conditions of the construction facilities, roads and working platforms are characterised by weak clay, organic soil or sand deposals of low density or a combination thereof. The size of loads from e.g. turbine parts, foundation- or tower segments or cranes for installation are challenging. Resulting loads from e.g. low motion vehicles and crane hardstandings are characterised by high deviator-stresses. Anyhow, only limited differential settlements are accepted. To scope with these issues, a wide range of foundation techniques are used as e.g. floating platforms, dynamic compaction, vertical bearing elements or piling. For all techniques, special attention has to be paid on local bearing capacity on the surface, in combination with total and differential settlement. The paper presents a major project on the example of a large nacelle factory, and addressing requirements on working platforms, making use of the combination of different foundation techniques. The geotechnical design by combining analytic models and numerical analysis are presented and discussed.
