OFFSHORE AND ONSHORE WIND PARKS

Using a system of different inspection methods and analysis for pre-operational and regular operational inspection of the wind generator elements ensures the earliest possible detection of any departure from the norm and occurrence defect. This allows avoiding potential damage and shortening the idle time of the wind power turbine.

 

Solwinda provides specialists to perform work of any complexity, on both onshore and offshore wind parks using suspended platforms as well as rope access method. All technicians have permissions and International certificates for rope access work in European countries and beyond.

 

Services we provide to Wind Parks:

  • Complete inspection and repair of the rotor blade including vortex replacement, aerodynamics exchange, rework, repair and exchange of blade equipotential bonding rails, LE TE cracks as well as LEP tape repair and exchange;
  • Inspection and repair of the wind turbine tower;
  • Inspection of root flange laminate cracks;
  • Rotor blade Lightning Protection System inspection, LPS continuity inspection, the 4-wire resistance measurement of the LPS;
  • Wind turbine gearbox inspection. Documenting of all visible bearings as well as the parts of the gearbox by borescope;
  • Tower and rotor blade bolt exchange;
  • Replacement and installation of electric cables;
  • NDT inspection, including rotor hub main bearing UT, PA UT inspection, dye penetrant testing (PT), ultrasonic testing and thermographic inspection;

GENERAL INSPECTION OF THE WIND TURBINE

Solwinda provides specialists to perform work of any complexity, on both onshore and offshore wind parks using suspended platforms as well as rope access methods. All technicians have permissions and International certificates for rope access work in European countries and beyond.

 

Services performed using suspended platform or rope access:

 

  • Internal and external inspection of the rotor blade
  • Inspection of root flange laminate cracks
  • Rotor blade Lightning Protection System inspection, LPS continuity inspection, the 4-wire resistance measurement of the LPS
  • Documenting of all visible bearings as well as the parts of the gearbox by borescope
  • Wind turbine tower inspection

WIND TURBINE GENERATOR NDT INSPECTION

Using a system of different inspection methods and analysis for preoperational and regular operational inspection of the wind generator elements ensures the earliest possible detection of any departure from the norm and defect occurrence. This allows avoiding potential damage and shortening the idle time of the wind power turbine.

 

Wind Turbine Inspection Methods:

 

  • Visual testing (VT) including visual inspection of rotor blades.
  • Dye penetrant testing (PT)
  • Ultrasonic testing: Manual UT and UTM method; Automatic P-scan and T-scan method
  • Thermographic inspection
  • Rotor hub main bearing UT, PA UT inspection

ROTOR BLADE INSPECTION

Solwinda provides inspection and repair services for rotor blades and wind towers. Our specialists use thermographic application technology for detecting defects in the structure of the wind turbine blades. Technicians compile inspection protocol depending on the scope and complexity of the matter.

 

Rotor Blade Inspection Methods:

 

  • Schematic drawing of the blade with the exact location of detected defects
  • List of individual defects with the dimensions of faults specified.
  • Photo and video material
  • Analysis of defects and recommendations for their elimination

ROTOR BLADE REPAIR AND OTHER SERVICES

By analyzing the results of the rotor blade inspection report, Solwinda specialists prepare recommendations and provide solutions for the repair of the detected defects. When analyzing the repair technology provided for the project, account must be given to the kind and nature of the faults as well as the acceptability of the defects. Blade repair is carried out by the specialists who have completed special training for working with composite materials (fiberglass and epoxy resin). To accelerate the repair process as well as to achieve the maximum quality of the blade repair, vacuum and curing methods are applied. After completing repair works for the structure, its paint coat is necessarily restored.

 

Services Offered:

 

  • Vortex replacement, aerodynamics exchange
  • Rework, repair and exchange of blade equipotential bonding rails
  • LE TE cracks
  • LEP tape repair and exchange
  • Lightning damage repair

 

Other Wind Parks services:

 

  • Wind turbine cleaning and drainage clearing works
  • Tower and rotor blade bolt exchange
  • Tower and rotor blade painting works
  • Replacement and installation of electric cables

 

Suspended Platforms

Use of suspended platforms in wind parks offers safe access to perform various inspection, maintenance and repair works in wind parks. Solwinda specialists have worked with temporary suspended platforms from companies such as Gebr. Käufer GmbH, Accessus, Spider by BrandSafway and others.

WIND TURBINE GEARBOX INSPECTION

Wind turbine gearboxes are regularly inspected to avoid repairs, downtime and to ensure a long lifespan. Endoscopic inspection is the only way to thoroughly inspect a gearbox or any other bearing. Borescopes are used to access the inner parts of the gearbox and to obtain high-quality images of the inaccessible areas that are prone to damage.

 

Gearbox inspection is aimed to identify the following fault types:

 

  • Varying degrees of bearing and gear wear
  • Micro to heavy pitting
  • Carbonization and effects of high or increased temperatures
  • Particle wear, fractures, corrosion and cracking
  • Light and heavy grooving or scoring
  • Spalling, fretting, scuffing and uneven wear patterns
  • Heavy ‘spots’ on bearing rollers or gears
  • False and true brinelling
  • Loading anomalies
  • Abrasive and erosive wear
  • Fluting and arcing effects
