ESOX
Offshore Weather Downtime Modeling Made Simple
Use our ESOX Zander and Excel tools to run weather downtime simulations across global offshore sites – free and easy.
The tools provide fast, advanced statistical calculations to help reduce delays and improve project build-out time. Integrated into our ESOX map containing a powerful ERA5 reanalysis database, you can download the metocean data in seconds instead of hours.
Free & User-Friendly
Paid & Customizable
ESOX Zander
Find your ideal weather window
in seconds
ESOX Excel
Simulate and analyze weather downtime for most offshore installation activities
ESOX Excel Custom
Get a tailor-made ESOX Excel download based on your exact project needs
ESOX Python
Get consulting-based Python simulations for high complexity scenarios
ESOX ZANDER
On-The-Fly Weather Window Calculations
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 downtime, factoring in minimum weather window duration, time of day limitations, and persistence exceedance percentiles.
Access the feature in our ESOX map by clicking any blue ERA5 dot. The results are delivered in an easy-to-read Excel sheet.
ESOX Excel
Downtime Modeling For Most Installation Scenarios
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.
ESOX Python
High Complexity Modeling
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.
Developed by Experts. Used by Everyone.
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.
Full Access to 30 Years of Global Wind and Wave Data
Integrated with three decades worth of ERA5 reanalysis time series data from Copernicus, including the 4 metocean parameters of mean wind speed at 10m heights, mean wind speed at 100m heights, significant wave height, and peak wave period, our ESOX map ensures that our embedded tools provide detailed statistical weather impact modeling for your installation – without the hours of download time.
