4. Enhancing Offshore Wind Farm Development Through Advanced 3D Ground Modelling

The rapid growth of the offshore wind industry in the global energy market requires reliable ground modelling to optimise project timelines and costs, with one key aspect being data visualisation. Displaying site conditions using 3D ground models is becoming more common and the use of a GIS-based method facilitates their development and implementation without the need for additional specialist software. The 3D environment allows for a comprehensive presentation of seabed and sub-seabed data, including outputs from geophysical, geotechnical, and environmental surveys, facilitating decision-making during the planning and installation phases. The model should be accessible to project stakeholders, ideally with minimum software requirements. 3D model data representation engages both technical and nontechnical stakeholders and broadens the understanding of the ground conditions and geohazards present at the site. In addition to providing a visualisation tool, the GIS model acts as a data repository reflecting project updates and allowing stakeholders to follow project progress. A central data repository ensures that all project team members have access to the most current and accurate information. This paper explores the implementation of a GIS-based 3D modelling technique and showcases it in a case study of a recent offshore wind farm project. The applications of 3D ground models for offshore wind farm development are also discussed
