This technical session explores leading approaches to offshore wind site characterization, crucial for maximizing project efficiency and minimizing risks across various water depths. Presentations will discuss multiple topics, including: 1. High-resolution seabed mapping using multibeam echosounders and sub-bottom profilers 2. Metocean data collection and analysis, including LiDAR and floating measurement platforms 3. Technological Advancements for environmental impact assessments and marine ecosystem surveys 4. Integration of multi-source data for comprehensive site modeling 5. Unique challenges of deepwater floating offshore wind site characterization Attendees will gain insights into the latest technologies, methodologies, and best practices for thorough offshore wind site assessment, with a special focus on the transition from fixed to floating installations in deeper waters.
