Wind Turbine Servicing

BIS Salamis has successfully adopted its preventive maintenance strategies and techniques used in its other energy sectors for use in maintaining and extending the life of wind turbine components. This proactive approach towards scheduled wind turbine maintenance is designed to save our customers money by reducing both the cost and downtime of unplanned repairs.

Wind Turbine Inspections

Inspections should be done periodically but it is more important to get them done at the beginning and end of the manufacture warranty. Our experienced personnel are trained to perform inspections on a variety of wind turbine components.

  • Borescope inspections of bearings and gears
  • Brake pad checks
  • Crack inspections of coupler and blades
  • Analysis of oils, hydraulic fluid and grease
  • Slip rings & brushes, cables & cable connections, fuses, voltage levels and batteries
  • Service lift, climb assist, ladder and fall arrest cable, hoist or crane

Turbine Oil Changes

Gearbox bearing failure is believed to be directly related to poor lubrication and lack of routine oil changes. BIS Salamis service technicians are trained to perform oil exchanges using state-of-the-art mobile oil exchange units. The units quickly connect directly to the gearbox, remove the oil using a vacuum system and filter the oil before refilling the gearbox. The entire process is completed in less than 3 hours.

Bolt Tensioning & Torque Checks

Using advanced tools and equipment, BIS Salamis technicians perform routine torque and tension checks of all interior and exterior bolts. Every application should be evaluated on its own to determine the optimum torque value for each application.

Major bolt suppliers should have tension indicating equipment necessary to determine the appropriate tightening values for their specific applications. A properly tightened bolt is one that is stretched such that it acts like a very ridged spring pulling mating surfaces together. Periodically checking the torque is necessary to ensure that stretching does not occur.
