Site Conditions Expertise
for Offshore Wind Excellence

Integrated survey, ground engineering, and metocean capability to de‑risk developments and enable smarter, safer design.

Complete Site Conditions Integration

At Wood Thilsted, we deliver a complete understanding of site conditions for offshore wind projects – from early‑stage feasibility to detailed design. Our integrated teams combine survey management, geotechnical and geophysical ground engineering, and industry‑leading metocean and climate analytics to give developers the clarity and confidence needed to make optimal decisions in complex offshore environments.

Integrated Expertise. Better Decisions. Lower Risk.

By uniting survey planning, ground engineering, and metocean intelligence into a single multidisciplinary team, we deliver:
  • Seamless data flow from seabed to structure
  • Early identification of risks and constraints
  • Fewer design iterations
  • Reduced installation uncertainty
  • Cost‑effective, buildable solutions
This end‑to‑end capability enables developers to move faster, reduce risk, and confidently progress through each phase of the offshore wind development.

Survey Management

World‑Class Survey Planning, Procurement & Oversight

Our survey specialists provide end‑to‑end management of geophysical, geotechnical, and environmental surveys. With extensive contractor‑side experience, we scope, tender, manage, and QA/QC survey campaigns to ensure data quality, cost efficiency, and safe offshore execution.

What We Deliver

  • Survey scoping and specification
  • Tendering and contractor evaluation
  • Offshore survey supervision and client representation
  • QA/QC and survey data validation
  • Integrated survey reporting aligned with design needs

Our deep understanding of how survey data feeds into engineering ensures every dataset is not only compliant, but genuinely useful for the next phase of project development.

Geophysical Ground Engineering

Market‑Leading Geophysical Interpretation

Our geophysical specialists form a centre of excellence in processing, interpreting, and integrating geophysical survey data for offshore wind. Many have direct survey‑contractor backgrounds, enabling efficient workflows and pragmatic, design‑focused outputs.

Capabilities

  • Geophysical data QC and interpretation
  • Seabed and shallow‑geology model development
  • Feature detection (geohazards, seabed obstructions, archaeology, cables, UXO)
  • Integrated ground models combining geophysics + geotechnics
  • Support for foundation, cable, and offshore substation design
By coupling geophysical insight with engineering need, we help clients reduce uncertainty and streamline later design phases.

Geotechnical Ground Engineering

Advanced Geotechnical Insight for Fixed‑Bottom, Deepwater and Floating Projects

Our geotechnical team specialises in interpreting ground conditions from seabed to bearing strata, using sophisticated soil–structure interaction (SSI) techniques to support foundation selection, feasibility, and detailed design.

Capabilities

  • Seabed & subsurface characterisation
  • Lab test evaluation & ground modelling
  • Soil–structure interaction modelling across all foundation types
  • Geohazard and georisk assessments
  • Seabed mobility, scour, and sediment transport analysis
Our work ensures developers understand geotechnical risks early and can progress with confidence through concept, FEED, and detailed design stages.

Metocean & Climate Analytics

Atmospheric and Oceanographic Intelligence That Powers Better Design

Our metocean and climate analytics team brings decades of industry experience and thousands of hours of atmospheric and ocean data analysis to every project. We generate accurate, high‑resolution environmental datasets to inform safe, reliable offshore wind design.

Capabilities

  • Metocean conditions assessment (waves, wind, currents, tides)
  • Extreme value analysis and long‑term climate statistics
  • Weather windows and operational downtime modelling
  • Climate trend analysis for long‑life assets
  • Environmental loading parameters for structural and cable design
These insights underpin everything from energy yield assessments to installation planning and detailed engineering.
