O&M Optimization

O&M Optimization
Maximized Performance and Structural Cost Control
Optimizing operations and maintenance for wind farms requires a deep technical understanding of the actual structural and operational behavior of wind turbines. Our approach transforms reactive maintenance models into predictive, risk-based strategies tailored to the specific conditions of each site and technology, with the goal of maximizing availability, extending asset life, and reducing total lifecycle costs.
This methodology integrates advanced structural analysis, type–site conditions, SCADA and CMS data, specialized inspections (including NDT), and historical maintenance review to adjust failure probabilities and prioritize interventions. The result is an optimized O&M model aligned with the wind farm’s technical risk profile, designed to enhance reliability, financial predictability, and residual value.
O&M Protocol Review
For Wind Assets
Standard maintenance programs are often based on generic assumptions and predefined schedules that do not accurately reflect the specific site conditions or the actual operational behavior of the wind farm. This approach can lead to significant deviations in technical risk management and O&M efficiency.
In particular, three structural limitations are commonly observed:
- Lack of adaptation to actual operational conditions, especially at sites with demanding type–site conditions.
- Homogeneous maintenance without prioritization based on structural criticality or failure probability.
- Disconnect between the maintenance strategy, real conditions (wind, operation, extreme events), and the accumulated degradation of components.
When decisions are made solely based on time intervals rather than actual condition or structural exposure, technical risk can be underestimated and O&M resources may be allocated suboptimally.
Maintenance strategy based on the asset’s actual condition
Our review of O&M protocols is based on a comprehensive technical assessment that combines structural load evaluation, operational data analysis (SCADA/CMS), specialized inspections (including NDT) and a detailed review of maintenance history. This approach allows us to characterize the actual condition of components and their accumulated exposure to risk.
Building on this technical foundation, we develop a site- and technology-specific assessment, redefining maintenance protocols according to the asset’s structural and operational profile. The objective is to optimize aging management, prioritize critical interventions, and bring component condition closer to its optimal structural state within its remaining service life.
The process consists of:
Technical evaluation of the current protocols
Critical analysis of the current strategy, identifying deviations between the maintenance schedule, actual operating conditions, and structural exposure.
Quantified identification of improvement opportunities
Prioritization of components and activities based on criticality, probability of failure, and operational and economic impact.
Development of risk-based protocols (FMECA)
Definition of medium- and long-term maintenance strategies through failure mode, effects, and criticality analysis, aligning O&M with the asset’s technical risk profile.
Final outcome
A clear and quantified understanding of the current structural condition, expected remaining life, and maintenance priorities, enabling improved reliability, availability, and economic efficiency.
Site condition–based maintenance protocol
Stepwise intervention model based on the asset’s real condition
Diagnostic Assessment and Technical Prioritization
Comprehensive characterization of structural and operational condition through load analysis, SCADA/CMS data, specialized inspections, and historical maintenance review. Includes FMECA analysis to classify components by probability of failure and impact, establishing objective intervention priorities.
Optimized Preventive / Life Extension
Condition- and structural-exposure-based interventions aimed at maximizing remaining service life without significantly increasing CAPEX Includes adjustments to inspection protocols, targeted reinforcements, and optimization of the O&M model based on criticality and accumulated damage.
Strategic Corrective / Preventive Transition
Actions targeting components with advanced degradation or high risk. Combines corrective repair with selective preventive redesign to reduce recurrence, stabilize the risk profile, and ensure medium-term operational continuity.
Comprehensive Structural Refurbishment
Major interventions when remaining service life is limited or structural risk is critical. May include replacement of major components, significant structural reinforcements, or redefinition of the asset’s operational model within a life-extension or fleet repositioning strategy.
