Free Weather Downtime Simulation

We are proud to announce the market launch of ESOX, our new tool for the simulation of offshore operations. Run weather downtime simulations across offshore sites worldwide – easy and free. ESOX has been developed after a decade of project planning and execution in the offshore wind industry.

How long does it take to install a typical offshore wind foundation? Which months are the best for blade repair? How does a project site in the North Sea compare to one in the Atlantic Ocean or the Sea of Japan? ESOX enables everyone to answer these and many more questions.

Two Functions in One

ESOX is a combination of sequential downtime modelling and a global data map, providing high-quality reanalysis metocean data. ESOX’s metocean dataset includes 30 years of global ERA5 data, provided by the European Centre for Medium-Range Weather Forecasts.

In order to increase industry transparency for offshore wind at a global level, it is essential that ESOX is accessible for everyone. Not only for industry specialists but also for the public. ESOX allows corporations, NGOs, students and governments to do their own analysis and benchmark between sites, technologies and projects.

ESOX+ for Complex Modelling

ESOX enables project participants to do most of the analysis, which is needed in an offshore wind project, themselves. For the more challenging, niche simulation cases, we provide assistance using the advanced and flexible ESOX+ modelling tool on a consulting basis.

Since 2015, our specialists have undertaken modelling using ESOX and ESOX+ for more than 5 GW of offshore wind capacity across North America, Europe, Asia and Oceania.
