SITE COMPLIANCE Module
Ensure Site Suitability with Confidence
SITE COMPLIANCE calculates the main checks required in site suitability assessments according to the IEC61400-1 standard, ed. 4 (2019), ed. 3 (2010) or ed. 2 (1999). For each main check the module evaluates if a wind turbine class (e.g. IIA) is suitable for the actual site and layout conditions.
Run reliable IEC-compliant assessments of wind turbine suitability — and reduce project risks from the start.
Comprehensive IEC Compliance Checks
The SITE COMPLIANCE module performs all the key evaluations required by the IEC 61400-1 standard (Editions 2, 3, and 4). It assesses whether selected wind turbine classes (e.g. IIA, IIIA) are suitable for your project site — helping you flag risks early and design compliant, cost-effective layouts.
Key assessments include:
- Terrain complexity
- Extreme wind
- Effective and extreme turbulence
- Wind distribution and shear
- Flow inclination
- Air density
- Seismic hazard and lightning risk
- Temperature extremes
All checks are calculated per turbine and easily compared across methods to test sensitivity and ensure the best-fitting model approach.
Support for Load Calculations
If any IEC checks are exceeded, the standard requires load calculations. Combine SITE COMPLIANCE with the LOAD RESPONSE module to validate turbine suitability through fast and precise response surface-based load assessments — delivering clear, per-component load indices.
Flexible Input Options
Whether you're working with:
- One or more on-site met masts (Meteo Objects)
- Calibrated wind statistics
- Full flow models
- Or no on-site measurements at all
SITE COMPLIANCE supports multiple input configurations — from simple offshore sites to complex terrain with advanced modeling.
Advanced Flow Model Integration
SITE COMPLIANCE integrates seamlessly with:
- WAsP
- WAsP Engineering
- WAsP-CFD
- External CFD tools via FLOWRES format
These models define wind field variations (wind speed, turbulence, inclination), allowing accurate calculation of site-specific conditions.
Users can also assign individual IEC design classes or apply flexible custom "Class S" models to each turbine in the layout.
User-Friendly with Deep Control
Designed for ease of use, the module allows quick setup of IEC assessments. At the same time, advanced users can tweak assumptions and model setups to run sensitivity analyses, test alternatives, and validate results with confidence.
Clear Reports that Highlight Risks
The output includes a detailed report summarizing:
- Compliance results for each turbine
- Key assumptions made
- Areas of risk or exceedance
Everything is laid out clearly to support engineering reviews and manufacturer collaboration.
Start Site Suitability Assessments with Confidence
Whether you’re validating turbine layouts or ensuring full IEC compliance, SITE COMPLIANCE is your go-to module for fast, reliable, and customisable assessments.
