LIFETIME EXTENSION
FOR LONG-TERM PROFITABILITY OF YOUR WIND TURBINES
An LTE (Lifetime Extension) study calculates the specific remaining lifetime of an operational wind farm. This service is essential because wind turbines have a certified lifetime of 20 years, calculated for ‘typical’ and not “specific” sites.
LIFETIME EXTENSION
OUR OBJECTIVES
Develop an operating strategy beyond the initial 20-year limit.
Define the maximum operating date for current machines.
Allow sufficient time for repowering studies and administrative approvals.
Plan for the replacement of structural components.
Calculate a margin for extending the operational life, which can be set between 23 and 40 years.
HOW WE WORK
DETAILED DESCRIPTION
Fatigue analysis
Reassessment of fatigue loads on critical components (blades, mast, nacelle, gearbox, generator) based on actual wind conditions at the site.
Operational data analysis
Use of SCADA data to understand actual wind patterns, production, shutdowns and operational constraints.
Structural integrity assessment
Verification of compliance with current standards and structural resilience to actual environmental conditions.
Maintenance history
Consideration of repair history and quality of maintenance performed.
