Wind power is an eco-friendly renewable energy resource that utilizes Earth’s rotation and breezes to generate electricity. Wind turbines can be found both on land and near bodies of water in order to take advantage of natural windflow there.
Once gearbox temperatures reach an alarm level, production stops and cooling occurs for some period.
Wind Power Gearbox Repairs
Wind energy offers enormous potential for energy production; keeping turbines operating smoothly and efficiently is of critical importance. Gearbox repair and refurbishment services make up an important element of Operation and Maintenance costs (O&M).
Wind park operators know that nearly half of unscheduled stops and maintenance costs relate to gearbox issues, prompting them to seek ways to enhance gearbox reliability and extend lifespan. Tackle this daunting challenge is no simple matter, especially in wind turbines where load and speed fluctuation is constant. Luckily, technologies used by other industries for rotating machinery such as vibration signal analysis is slowly being adopted by WT operators – helping identify failures before they occur to decrease maintenance times while increasing equipment availability.
Wind Power Gearbox Services
Wind turbine gearbox maintenance is an integral component of successful operations and operational costs, having an enormous influence on productivity levels and operational expenses. To reduce downtime, current maintenance strategies involve monitoring temperature of each gearbox and, once it reaches a predefined critical threshold, cooling it off immediately to restore efficiency and return productivity levels to acceptable levels. After an agreed upon number of cooling actions are taken by maintenance agents, replacing or overhauling may occur at their discretion.
Replacing gearboxes can be costly and require significant downtime, as well as being hard to justify due to limited capital available for spares storage across an entire fleet of wind turbines. Many customers therefore choose direct drive systems despite increased O&M costs; this presents developers and investors with the difficult challenge of balancing spend with theoretical lifespan extension.
Wind Power Gearbox Rebuilding
Gearboxes are an integral component of wind turbines, increasing rotor speed to match generator output. A gearbox failure can result in massive production losses; replacing one requires removal from nacelle, transportation to site, crane rental cost and mobilisation fees as well as downtime due to repair work time.
Wind turbine gearbox repair and refurbishment market growth can be attributed to rising industrialization and urbanization worldwide. Each country is placing more focus on renewable energy production goals in their energy strategy plans for the upcoming years, driving investments into this sector. Furthermore, global electricity demand continues to surge leading to an increase in wind power production.
Wind Power Gearbox Refurbishment
Operating and maintenance (O&M) costs make up one quarter of lifetime project expenses, so keeping gearboxes functioning optimally remains essential to project profitability. Failing gearboxes could result in high replacement costs as well as unscheduled downtime that erodes project returns.
Replacing a damaged gearbox is an expensive and time-consuming endeavor, involving removal from its nacelle, disassembly and shipment to a repair center. To minimize costs and downtime for wind farms, refurbishers often offer units as stock exchange so as to minimize replacement timeframes and keep downtime to an absolute minimum.
The wind turbine gearbox repair and refurbishment market can be divided into North America, Latin America, Asia Pacific and Europe; Europe holds the greatest share due to an increased emphasis on renewable energy sources like wind power.
Wind Power Gearbox Reconditioning
Wind turbines have seen increasing use over the past decade to combat fossil fuel depletion and generate significant amounts of power at relatively low cost per unit. Deployed both onshore and offshore, their use requires regular maintenance on both their nacelle and components – an indispensable task.
Wind turbine gearboxes must withstand massive torques, moments and forces that put pressure on their seals and lubrication systems and could compromise mechanical performance, leading to stress concentration or tooth damage in their systems.
In case of damage to a gearbox, its temperature exceeds an predetermined threshold and cooling actions ensue, leading to energy production losses and forcing an operator to make the difficult decision whether to replace it with an identical one or undergo an overhaul which restores it back to as good as new condition.
