An increasingly volatile climate and powerful winds are an endurance test not only for people, but also for machines. But what would appear to be a disadvantage could actually be a significant opportunity for an entire industry – at the very least for those whose wind turbines can withstand extreme conditions.

A large number of wind turbines have been in operation for many years, leading to inevitable wear. At face value, this may be considered problematic – but on closer inspection, aging wind turbines could present a world of opportunity.

Operation and maintenance (O&M) costs represent a large portion of expenditure for wind farm operators. Failure to implement an effective strategy may result in increased costs or machinery failure. For this reason, it is important to take a statistical approach.

The experts have spoken: A survey carried out at the 2017 SKF Wind Farm Management Conference has indicated that the global wind operations and maintenance (O&M) market is expected to grow by around 15% by 2020. Read on to discover what the findings of the poll could mean for the wind industry.

Electrical erosion is a common cause of bearing failure – something that can lead to complications for wind farm operators, such as downtime or reduced productivity. However, there is a cost-effective solution to this. SKF collaborated with a wind turbine generator manufacturer to resolve the issue.

Wind turbines are among the most reliable of power-generating technologies. When they do break down, however, it is often due to poor lubrication of the gearbox bearings. Proper lubrication can keep a turbine operating reliably and efficiently. Finding the right oil – and system with which to apply it – is vital.

Operation and maintenance (O&M) costs can constitute up to 25% of a turbine’s levelized energy cost over its lifetime. Technology that helps reduce maintenance and downtime is therefore crucial. In the previous article of this two-part series, we examined four of the most common bearing failure modes. This time, we will look at black oxidation – an effective solution to improve operational reliability.

White etching cracks are a symptom of bearing failure. SKF researchers and application engineers discuss how to tackle the challenges and reduce the risk of this failure mode.

Big data is enhancing operations and maintenance (O&M) in the wind power industry. By harnessing insights gleaned from this explosion of information, companies optimize turbines to reduce costs and increase efficiency. Yet as effective as statistical models are, the intermittency of wind is inescapable. This calls for a solution that allows turbines to learn from and adapt to changing conditions autonomously.
