Offshore Wind Installation Vessel Cost & Weather Downtime Tool

Estimate wind-turbine installation vessel days, weather downtime, marine spread cost, fuel, support-vessel expense and cost per turbine or installed megawatt. Advanced mode separates foundation and turbine installation phases, multiple WTIVs and an editable support-vessel fleet.

Installation Schedule
Productive installation time adjusted for weather operability
Marine Spread Cost
WTIV, support vessels, fuel, port logistics and contingency
Unit Economics
Cost per turbine, cost per MW and weather-delay exposure

Installation Vessel Cost Results

Simple WTIV and support-vessel estimate

Enter project data
Enter turbine count, productive installation time and weather operability to estimate schedule and marine installation cost.
Planning estimate only. Actual offshore wind installation cost depends on turbine and foundation design, water depth, soil and seabed conditions, jack-up capability, crane capacity, feeder strategy, port layout, lift plans, metocean conditions, vessel availability, contract structure, marine coordination, regulatory requirements and project sequencing. Weather operability is a simplified planning input and does not replace a metocean accessibility study, installation simulation or vessel-specific engineering analysis.
