How We Came Up with ESOX

We have developed the weather downtime simulatation tool ESOX after a decade of experience working with planning, simulation and execution of offshore wind projects. The tool is mainly used for the analysis of transport, pre-assembly, load-out, transit, installation, commissioning and operation activities.

Identify Critical Activities
ESOX DATA EXAMPLE

Identify Critical Activities

Identify the most cost-effective installation setup by exploring what activities are causing the most downtime and by analyzing how changes in operational constraints impact downtime.

Identify Critical Weather Parameters
ESOX DATA EXAMPLE

Identify Critical Weather Variables

Identify critical weather variables for each installation scenario by using the breakdown of how individual weather variables contribute to the total downtime.

Generate Weather Calendars for Time Scheduling
ESOX DATA EXAMPLE

Generate Weather Calendars for Time Scheduling

Generate monthly weather calendars for Primavera P6 and Microsoft Project.

Evaluate Seasonal Downtime
ESOX DATA EXAMPLE

Evaluate Seasonal Downtime

Quantify seasonal variations in weather downtime to identify the preferred installation periods.

Forecast Milestone Dates
ESOX DATA EXAMPLE

Forecast Milestones Dates

Estimate completion dates for each position for any confidence (percentile) value. Example displays forecasted completion dates for a construction campaign with 70 positions, starting January 1st.

ESOX Python for Advanced Modeling

The capabilities of ESOX cover the needs of most offshore wind project projects. However, for more challenging, niche simulation cases, LAUTEC’s specialists analyze high-complexity scenarios using the advanced ESOX Python tool on a consulting basis. 

ESOX and ESOX Python has been used for offshore wind projects across North America, Europe, Asia and Oceania, reaching 5GW of installed capacity.
