ESOX+ for Complex Scenarios

As a project participant, you can do 80% of the analysis, which is needed in an offshore wind project, yourself. For the more challenging, niche simulation cases, Lautec’s specialists can analyze high-complexity scenarios for you.

Our specialists use the advanced ESOX+ tool to provide fully customizable and tailored-made simulation models for individual needs.

As a consultancy, Lautec has been using ESOX+ for the modelling of more than 5 GW of offshore wind capacity across North America, Europe, Asia, and Oceania.
