Technical Assessment

The foundation and the tower form the backbone of a wind turbine. Our experts examine the concrete tower, investigate damage and its causes, and test the concrete for stability. They give comprehensive advice on necessary measures. We also keep an eye on the wind farm's infrastructures and crane pads.

Our services include:

• Assessment of components
• Damage assessment
• Recommendations for renovations
• Coordination and supervision of the renovations including bidding and billing

Gearbox damages are the main cause for prolonged downtime in the life of a wind turbine. We offer bespoke condition-based technical assessments in order to plan ahead and to optimise any necessary repairs. This minimises additional damage or downtime and reduces repair costs and yield loss.

We offer specific damage assessment of individual components or a full scope video endoscopy of the gearbox. We determine the gravity of the situation and make expert recommendations on how to proceed. We always have the best interest of the owner in mind.

Our services include:

• Continuous condition monitoring of the gearbox
• Full scope endoscopy of all accessible gearbox stages and the oil system
• Current condition assessment of the gearbox for example before a contract extension or at the end of warranty
• Reduced scope endoscopy focusing on typical damages for each particular gearbox type
• Evaluation of the endoscopy and recommendations for action

The rotor blade is crucial for high yields: Exposed to wind and weather, it must function reliably over the course of 20 years. Only when the rotor blade is in perfect condition will the turbine deliver the desired yield. Repairs that are not completed at the optimal time increase the cost of repairs and the yield loss many times over. Our experts thoroughly and competently inspect and evaluate the condition of the rotor blades in order to be able to plan timely repairs.

Our services include:

• Condition-based and recurring inspections of rotor blades
• All tests using rope access technology complying with any relevant standards, guidelines and insurance requirements
• Lightning protection tests from the rotor blades to the discharge onto the ground

Bats, birds and other protected species often result in certain conditions of planning permits that have a significant impact on yields. Additional restrictions regarding noise, shadow flicker and ice-throw require competent expertise during the entire operational life of a wind turbine.

Our team of environmental experts benefit from their long-term practical experience in the field of nature and species protection and other environmental concerns. They implement solution-oriented and cost-effective measures to ensure environmental compliance.

We create innovative management concepts to minimise yield loss. Since 2010, we have carried out more than 100 bat monitoring campaigns. In addition, we develop sound measurement campaigns for complex sites and supervise them. Our staff evaluate monitoring and measuring reports and negotiate with authorities in the best interest of our customers in order to optimise the wind farm commercially and technically. In addition to our customers, our professional colleagues from other departments also greatly appreciate the expertise of our environmental experts.

Our services include:

• Implementation and analysis of monitoring and measurement reports
• Performance analysis and bespoke recommendations
• Concepts for yield optimisation and compliance with species protection requirements
• Negotiations with authorities in the interests of our customers
• Optimisation of the subsystems
• Ecological supervision of construction
