Extending the life span of a wind turbine becomes the prime focus once a wind farm is commissioned.
Regular wind turbine maintenance and service is required to maintain good working order and prevent unnecessary downtime. Surespan Wind provides the right combination of expertise and equipment for the following maintenance services.
Due to the high velocity of turbine blades and many objects from which they may receive contact, blades require regular inspection, maintenance, and repair to ensure optimal performance. Surespan provides the following blade related services:
- Photo inspections using a high power lens
- Hands on inspection using a suspended platform
- Internal inspections
- Lightening system testing
- Leading edge erosion
- Lightening damage
- Core repairs
- Vortex generator repair/replacement
- Minor cosmetic to elaborate structural repairs
Other Blade-related Areas:
- Tower cleaning
- Blade cleaning
- Leading edge protection upgrades
- OEM upgrades (dyno tails , vortex generators , stall strips , etc.)
Our elevator maintenance packages meet unique customer needs in accordance with TSSA codes. The objective is to provide wind farm owners with cost-efficient and code-compliant maintenance. We want to maximize both the life expectancy and the reliability of the elevator system.
Our goal is to provide unequalled service and safe operation. We provide our customers with quality maintenance programs so they can focus on what they do best, and not have to worry about managing their contractor.
Scheduled Maintenance Options
There are a number of regular scheduled maintenance options that Surespan performs for established wind farms.
Gearbox Oil Changes
Our mobile gearbox oil change system connects directly to the gearbox to decrease spills and drips, eliminate heavy lifting injuries and dangerous spills. This system makes it easy to vacuum in fresh oil directly from barrels.
With the close tolerances inside the gearbox, even brand new oil is not clean enough to prevent internal damage to gearbox components. Our system uses a CC Jensen filtration system that filters the oil to a 16/14/11 ISO cleanliness level.
Yaw Puck Maintenance
Wear pucks and friction pads act as brakes in wind turbines. This yaw system contains 12 or 18 yaw pucks that are evenly spaced around the frame of the nacelle and provide a frictional force against the yaw slew ring. The yaw system can potentially lead to noise pollution and chattering sounds that can be heard several miles away.
The yaw puck comes into contact with the sliding surface of the yaw bearing. An adjustable bolt provides pressure to a pressure plate, which, in turn, presses against a set of spring washers, and the washers apply the force to the yaw puck. Pressure of the yaw pucks on the sliding surface of the yaw bearing is always present, and in order to yaw the turbine the yaw motors have to overcome the force of friction that the pucks produce. The torque on the bolt is checked in each maintenance cycle.
