Load Calculations & Continued Operation

Identify reserves. Support decisions.

Using generic servo-aeroelastic models, reconstructed design loads and site-specific simulations, we provide a robust assessment of the actual loads acting on a wind turbine.

The objective

Identify reserves. Support decisions.

Load calculations link aerodynamics, structures and control. Comparing the original design with the actual site reveals available reserves, limiting components and measures that support safe and economical operation.

Scope of services

Turning complexity into clarity.

We combine the modules to suit the project phase, from a focused individual assessment to an integrated analysis.

Generic Turbine Models

Parametric servo-aeroelastic models couple aerodynamics, structural behaviour and control.

Design Load Reconstruction

Reconstruction of the original load assumptions and design limits as a reliable reference.

Site Loads

Calculation of actual loads under the project's wind, turbulence, wake and operating conditions.

Component Assessment

Component-specific analysis of rotor blades, hub, tower and other relevant structures.

Continued Operation 20+

Identification of load reserves and limiting components as the analytical part of a continued-operation assessment.

Operational Optimisation

Assessment of operating modes and shutdown strategies with a view to reducing loads while maintaining availability and yield.

Project process

A structured path from data to results.

  • Build the Model Base

    Turbine geometry, structural parameters and controller behaviour are transferred into a robust calculation model.

  • Reproduce the Design

    We reconstruct the design conditions and establish a consistent reference for the load comparison.

  • Simulate the Site

    Relevant load cases are calculated using project-specific wind and operating conditions.

  • Assess Components

    Design and site loads are compared component by component, documented and technically evaluated.

What you receive

Results you can put to work.

  • Structured comparison of design and site loads
  • Component-specific identification of reserves and exceedances
  • Analytical basis for continued operation and structural integrity
  • Starting points for operational and controller optimisation
Input data

What we need to get started

  • Turbine type, configuration and relevant documentation
  • Site coordinates, wind-farm layout and operating data
  • Wind and turbulence parameters from the site analysis
  • Objective: suitability, continued operation, neighbouring-turbine effects or optimisation

Missing data is not an obstacle. We identify gaps early and agree appropriate substitute assumptions or additions with you.

Frequently asked questions

Brief answers.

Why is a generic service-life assumption insufficient?

Two identical turbines can experience very different loads due to site conditions, turbulence, wake effects and operation. The individual load history is decisive.

When should continued operation be assessed?

Ideally before the end of the twentieth year of operation. This leaves time to supplement data, carry out repairs, coordinate partner inspections and plan the commercial case.

How is the practical inspection covered?

IDASWIND works with independent accredited or certified partners. The analytical work and practical inspection are combined to form a consistent overall assessment.
