The Fourth International Symposium on Frontiers in Offshore Geotechnics (ISFOG) follows the previous symposiums in Oslo, Norway (2015) and Perth, Australia (2010 and 2005). DFI and Geo-Institute of ASCE are managing the event under the auspices of ISSMGE Technical Committee 309 on Offshore Geotechnics. The symposium features the fifth McClelland Lecture and strives to continue providing a specialist forum for practitioners and academics to share solutions and new ideas that address the dynamic challenges of working in offshore design and installation. ISFOG 2020 will highlight emerging technologies related to data science and emphasizes the recent surges in offshore renewables development in the United States and globally. Join us at the University of Texas at Austin in August 2020.
