When managing spare parts stock, companies face a significant challenge: maintenance requirements vs. financial resources. This can be a difficult task as mismanagement of either can have serious consequences. So what can operators do to ensure they have this under control?

The advantages of wind are clear: it is an inexhaustible and environmentally friendly energy source. Furthermore, the technology to harness its power is already well established. However, although wind is a proven eco-efficient energy source, why is it struggling to achieve status as a cost-efficient one?

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.
