Abstract
Summary
This abstract discusses the development of geological and geotechnical ground models through examples from Denmark and South Korea. The integrated ground model developed in the European offshore wind market reflects the markets higher maturity compared to the South Korean more early-stage market with pilot-scale installed capacity and rapid expansion for ambitious targets. For both countries lean and tailored ground model development is key to support the business cases for the offshore wind farm projects and thereby the renewable transition.
In this study we show case ground model development for a typical South Korean Yellow Sea project concerned with establishing the depth to bedrock within foundation depth. Data interpretation is hindered by gas-blanking and lack of data quality. In comparison we show results from a ground model developed in the North Sea, Denmark, with high quality data imaging high strength soils found prevailing in foundation depth. Here soft clays in channels are in focus toward derisking the ground conditions. The study shows that even with lower quality data and challenges from extensive gas-blanking results can be obtained from a tailored and lean ground model development in Korea.
