Abstract This study focuses on enhancing our understanding of key factors influencing the construction of floating offshore wind farms along the west coast of the United States. It explores geophysical, geological, and geotechnical aspects, specifically aiming to predict and address key considerations for cable and anchor installation. The study examines various factors, such as seismic activities including earthquakes and tsunamis, liquefaction potential, submarine landslide potential, and steep seabed gradients, which are critical in shaping engineering approaches. Also, the identification of hard grounds, paleochannels, soft and organic soils, fluid expulsion features and shallow gas pockets are explored for their influence on design and construction. The research also emphasizes the importance of recognizing sensitive marine habitats and understanding existing ocean usage and anthropogenic features for environmentally conscious and safe project planning. By proactively engaging with these factors, this study aims to provide insightful recommendations and strategies for the successful development of floating offshore wind farms in this region. It underscores the importance of comprehensive risk assessment and customized engineering solutions to ensure the long-term viability and sustainability of these renewable energy projects.
