Leading Edge Repairs

BACKGROUND

The Leading Edge of the rotor blade is one of the most stressed components on the rotor blade, which causes early erosion of the Leading-Edge due to the high rotational speed of a rotor blade together with different weather conditions throughout the year.

If the Leading-Edge is eroded, the underlying composite structure go be damaged, which causes further damages to the rotor blade and also affects the efficiency and performance of the wind turbine.

Leading Edge Protection (LEP) Systems help combat the erosion of blades leading edge.

Blade Power RE Services works with the leading manufacturers and technologies on the market, to provide the best Leading-Edge protection against wear and tear.

The preventive and corrective methods on the Leading-Edges leads to:

• Lower maintenance cost by timely preventative maintenance
• Regain lost power curve due to re-establishment of the aerodynamic profile of the leading edge.
• Increase lifetime expectancy of the blade.

Blade Power RE Services offer customized Leading-Edge repairs,such us:

• Repair and rebuild of the Leading Edge profile including serious erosion damages and structural laminate damages.
• Applying of Leading Edge Protection (LEP) systems according to customer requirements from the best-in-class Leading Edge protection manufacturers: MANKIEWICZ, BERGOLIN, TEKNOS, BELZONA, AEROX, POLYTECH and ARMOUR-EDGE.
  

Structural Blade Repairs

BACKGROUND

Our teams of trained and qualified blade technicians with an extensive professional experience, are able to repair complex structural blade damages and rebuild the damaged blade to their original strength and performance. As a key element in the operation of wind turbines, the conditions of the rotor blades are crucial to ensure the efficiency and performance of the wind turbine.

All structural blade repairs are performed according to OEM standards with DNV-GL-certified materials at follow the specified repair instructions under using vacuum pressure or vacuum infusion technology.

For this blade repair service, we operate with specialized blade access platforms, to guarantee the highest quality repair results and return the blades to its intended life cycle.

A large selection of our own blade access platforms from various manufacturers, ensures that our services are available for a wide range of blade repairs of different blade types.

Our newest full covered suspended working platforms type TERRA 1.1 can also be used in challenging weather conditions and at night, so that larger blade repairs can be carried out in the shortest possible time in order to reduce the downtime of the turbine.

Blade Power RE Services  offer customized structural blade repair services, such as:

• Repair of any damages to the main laminate and blade shell laminate
• Repair of any damages to the core material such as balsa or foam
• Repair of any damages to the web, glue or internal laminate
• Repair of any damages causes by lightning
• Repair of any damages of the lightning protection systems
• Repair of transportation or construction related damages.
  

Blade optimizations

BACKGROUND

Due to the progressive further development in the area of rotor blade designs and performance, further developments are also being available for rotor blade types in operation.

This possibility of blade optimization for rotor blade types that have already been in use for several years, increase the efficiency and energy production of being installed wind turbines.

It is also possible to reduce the noise level of the blades during operation through subsequent optimization of the rotor blade design.

Optimizations can also be carried out on existing LPS systems, to provide better protection against lightning damages.

Blade optimizations can be done by creating a safe and stable working environment near the wind turbine, or with our blade access technology. Our flexible approach will allow you to safely complete your blade optimizations.

Blade Power RE Services offer customized blade optimization services , such as:

• Installation of Vortex Generators on the suction side of the rotor blade, to create a better air flow over the blade surface, resulting in less turbulence and more torque to turn the rotor and generate up to 2-4% more revenue.
• Installation of trailing edge serrations on the trailing edge of the rotor blade to reduce noise from the rotor blades during operation by up to 3 db(A).

Blade Repairs on the ground

BACKGROUND

All our blade repairs and optimizations can also be carried out on the ground, in a repair area protected from external weather conditions.

In the event of a generator or gearbox replacement, time and cost-saving prevent blade repairs or blade optimizations can be carried out directly on site.

For large blade repairs, the work progress can also be carried out in a 3-shift system at day and night.

This repair process addresses not only the economics, but also the operational aspects, ensuring that the turbine downtime is minimized and therefore energy production is available again sooner.

Blade Power RE Services offer customized ground repair services, such as:

• Repair of any damages to the main laminate and blade shell laminate
• Repair of any damages to the core material such as balsa or foam
• Repair of any damages to the web, glue or internal laminate
• Repair of any damages causes by lightning
• Repair of any damages of the lightning protection systems
• Repair of any transportation and construction related damages
• Blade Optimizations
