Topic: From Data to Design: Integrated Seismic and Geotechnical Quantitative Ground Models for Offshore Wind

Speaker: Esben Dalgaard, Managing Director and co-founder of SolidGround

Abstract

A critical factor in scaling up the development of wind farms in a cost-effective and timely manner, 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 recent and diverse offshore wind projects, illustrating the role of quantitative 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

Speaker Biography

Esben Dalgaard is Managing Director and co-founder of SolidGround, with over 10 years of experience in advanced seismic reservoir characterization, integrating geophysics and geology. He specializes in UHRS seismic for wind farm and geohazard site investigations and has developed seismic inversion methods applied across offshore wind, geothermal, and hydrocarbon projects. Esben has extensive experience integrating geophysical and geotechnical data to support quantitative ground modeling across diverse global sites for offshore foundations projects, including wind farms and energy islands.

This meeting is organised by the Geophysics SIG committee.
