Leaders in global offshore engineering
Wood Thilsted is different from other engineering consultancies. We have brought together leading offshore engineers with structural, geotechnical, geophysical, survey management, energy and climate analytics experts – all in one organisation.
Efficient foundation design
Managing project costs is always of the upmost importance but in a highly volatile steel market this is more important than ever before. Wood Thilsted’s foundation design engineering stands out in terms of speed, safety and savings:
Pioneering Software
Our in-house software and data analysis are industry leading and not available with any other design firm.
Unmatched Expertise
Our teams are the best engineers, having worked on most of the offshore wind projects in the world. We have decades of experience in our teams.
Agility and Speed
Our project teams are agile and fast. We can handle design changes in hours instead of weeks, producing the most steel efficient designs at the fast speeds.

Primary Structure Design Expertise
At Wood Thilsted, our approach to primary structure design for offshore wind is second to none.
We lead the industry in monopile design, complemented by extensive expertise in jacket structures and a pivotal role in advancing floating foundation solutions.
From early screening to detailed design or full lifecycle support, we deliver solutions that save time and reduce costs without compromising quality.
Our integrated in-house load assessment capability combines aero-elastic analysis with hydrodynamic loading and seismic effects, providing a fully comprehensive approach at the earliest stages of a project. For later phases, we cover all structural forms – from monopiles to gravity bases – and develop novel solutions from first principles when required.
Whatever your challenge, wherever you are in the world, talk to us. We thrive on solving complex problems.

Innovation for Safer, Smarter Offshore Structures
At Wood Thilsted, innovation isn’t just about efficiency in foundation design — it’s about driving cost savings and improving health and safety across secondary offshore structures.
We’ve developed pioneering solutions for work platforms, ladders, boat landings, and more, making access, egress, and work tasks safer and faster.
Our approach combines cutting-edge 3D modelling with close integration across teams and technologies, ensuring every design is practical, efficient, and built for real-world conditions.
When expertise and collaboration come together, the results are extraordinary.

Geotechnical Engineering & Design
Geotechnical Expertise for Optimised Foundation Design
At Wood Thilsted, our geotechnical interpretation and state-of-the-art soil–structure interaction techniques ensure highly optimised foundation designs for offshore wind projects.
In the early stages of project development, our geotechnical team provides a full suite of services to assess the feasibility of fixed-bottom or floating foundations. For long-term partnerships, we deliver advanced seabed interaction analysis, including seabed mobility assessment, scour assessment and protection design, cable route engineering, jack-up feasibility, and leg penetration studies. These services integrate seamlessly with our primary steels team to deliver efficient, tailored designs for every foundation type.
Whatever stage your project is at, you can rely on our geotechnical expertise to put you ahead of the rest.

Geophysical Expertise for Offshore Wind Development
Our team of geophysical specialists forms a market-leading centre of technical excellence for scoping, tendering, managing, and evaluating all geophysical surveys required for offshore wind farm development.
Many of our experts have years of experience working directly with survey contractors. Combined with our solutions-focused approach to ground modelling and seabed interpretation, this ensures efficient, high-quality support for clients and seamless integration with our in-house foundation design teams.
We also provide advanced GIS and data management services, delivering user-friendly spatial mapping that helps identify opportunities and constraints quickly and effectively.
With Wood Thilsted, you gain geophysical insight that drives smarter decisions and optimised designs.

Transport & Installation
Transport & Installation Expertise
At Wood Thilsted, our integrated in-house expertise, combined with global and local experience, ensures every design we deliver can be installed efficiently and effectively.
If you already have a design and need to make it happen, we work with you to ensure transport and installation is as cost-effective and seamless as possible. We’re contractor-agnostic, so whoever you choose, we can collaborate to optimise precise locations, adjust boundaries, or fine-tune proposed methodologies.
Looking ahead? So are we. Our team also analyses and designs floating structures, using Orcaflex combined with our own technologies to support the energy transition.
Whatever your challenge, wherever you are, talk to us – we make complex installations happen.

Climate Analytics & Loads
Climate Analytics & Loads Expertise
The Climate Analytics and Loads department at Wood Thilsted brings together wind and metocean expertise in a truly integrated way.
Our energy specialists come from world-leading wind consultancies for both onshore and offshore environments, working hand in hand with experts from established metocean analysis outfits. This unique combination creates one of the most innovative teams in the industry, with decades of experience and thousands of years of atmospheric and oceanographic data analyses under their collective belt.
This expertise underpins high-quality Energy Production Assessments and Site Conditions Assessments, as well as studies that depend on detailed climatic knowledge, such as Weather Window Analysis and Measurement Campaign Specification.
Simply put, whether you need an accurate estimate of an onshore or offshore wind farm’s future energy production or the most efficient analysis for the detailed design of every foundation, we’re here to help you succeed.

Survey Management
Survey Management & Site Development Strategy
Every site is different, and from the outset, our team establishes a clear site development strategy designed to manage time and cost effectively.
This means survey management scopes tailored to the needs of each project stage – never a one-size-fits-all approach. We can step away after defining the scope or take full responsibility for running tenders and managing the process.
The choice is yours – and we’re here to make it seamless.

Project Delivery
Offshore wind projects are highly complex, which is why Wood Thilsted’s Project Delivery division brings together experienced project directors to ensure robust governance and a relentless focus on risk reduction – delivering projects on time and on budget.
Unlike many consultancies, our directors play an active role in delivery and decision-making, guided by the principle of constructive support. This means:
- Leveraging our exceptional offshore wind experience to assist and guide clients through any challenge.
- Proactively managing risks ahead of time to keep priorities on track.
- Using smart tools to provide clients with the management information they need, when they need it, in the systems they prefer.
In short, we look out for you so you never end up in uncharted waters. And if the unexpected does happen, we’re ready to help – just ask our clients about the positive feedback we’ve earned.
