UHRS Inversion Techniques at Different Stages of Offshore Wind Farm Development

To meet the global targets for wind power deployment by 2030—estimated to require over 2,000 GW of total installed capacity to stay on track for net-zero emissions by 2050 (IEA, 2023)—the industry must rapidly scale up the development of wind farms in a cost-effective and timely manner. A critical factor in achieving this is a robust understanding of subsurface conditions, including geotechnical parameters and design-relevant behaviors.

A key enabler in this process is the quantitative joint interpretation of ultra-high-resolution seismic (UHRS) data and geotechnical investigations, which can significantly enhance subsurface mapping accuracy and reduce uncertainties. This, in turn, supports better decision-making throughout the project lifecycle.

In this presentation, we will examine three recent and diverse offshore wind projects, illustrating the role of integrated ground modeling in various project phases:

• Early-phase projects with sparse, low-quality data
• Mid-to-late-stage developments characterized by dense, high-quality datasets Each case presents unique challenges and opportunities, shaped by data availability, project maturity, and decision timelines.

We will demonstrate how effective, quantitative ground modeling can support:

• Early and mid-stage design and planning of geotechnical campaigns
• Later-stage design processes, including robust uncertainty analysis and risk mitigation
