Create free custom weather window tables in seconds with ESOX Zander.
With the tool, you can customize your project parameters to generate month-to-month assessments of expected weather downtime, factoring in minimum weather window duration, time of day limitations, and persistence exceedance percentiles.
The results are delivered in an easy-to-read Excel sheet.
ESOX Excel provides free statistics-based analyses to predict downtime and duration for a wide assortment of offshore activities, enabling project members to independently carry out most of the necessary analysis for offshore campaigns.
Just like ESOX Zander, ESOX Excel is integrated into our global map and can be downloaded by clicking any blue ERA5 data point.
For simulations that require more personalization than our free service offers, we provide custom-built, paid versions of ESOX Excel based on individual client requests – a service which we call ESOX Excel Custom.

The capabilities of ESOX Excel and Excel Custom cover the needs of most offshore wind project projects.
However, for more challenging, niche simulation cases, LAUTEC’s specialists analyze high-complexity scenarios using our advanced, flexible in-house ESOX Python tool on a consulting basis.
We developed ESOX after a decade of experience working with planning, simulation, and execution of offshore wind projects.
We wanted a simpler way to answer questions like: How long will it take to complete the proposed foundation installation campaign? Which months are the best for blade repair? How much weather downtime did your contractor calculate into the lump-sum price?
Since 2015, the tools have been implemented for modeling transport, pre-assembly, load-out, transit, installation, commissioning, and operation activities for offshore wind projects across North America, Europe, Asia, and Oceania.
Our ESOX map is integrated with three decades worth of ERA5 reanalysis time series data from Copernicus. This includes the 9 metocean parameters of mean wind speed at 10m heights, mean wind speed at 100m heights, estimated wind speed at 150m heights, wind gust, significant wave height, peak wave period, relative humidity, total precipitation, and mean temperature at 2m. As a result, our embedded tools are able to provide detailed statistical weather impact modeling for your installation – without the hours of download time.
