What Is The Most Cost And Time Effective Strategy To Inspect Blades?

By the beginning of 2015, there were nearly 270,000 individual wind turbines operating globally. The 800,000+ blades spinning on these turbines are battered by the elements during operation and require maintenance and repair. For this reason, blade inspections are becoming more and more important and traditional strategies with inspections accomplished from the ground are being complimented by new approaches which have been developed including UAVs, telescope, rope access, and the use of helicopters. During this panel, we will attempt to bring a fresh approach to blade inspection, and identify which technologies makes more economic sense, but also what is the long-term view to ensure reliability based on image interpretation. 

Participants include:

Roman Sobottka, Head Of Blade Service, Nordex

Michael Pedersen, Senior Blade Engineer, Statkraft

Joey Van Acker, Belwind WTG Asset Manager, Parkwind

An Industry’s Effort: Practical Steps Towards The Categorisation Of Damages And Defects

When it comes to blade performance, it is important to focus on more than purely exploiting energy from them. It rather means having a close look at what made a blade under perform, spot defects and damages due to the external environment, looking at composite materials, and mistakes made during the manufacturing phase. It also means finding an easy, quick and cost-effective way for utilities to take action and avoid losses. With a lack of standardisation in the way that the industry categorises such defects and damages, the process becomes more complicated and time is wasted. This panel aims to bring key stakeholders together to take practical steps towards a global categorisation approach.

Participants include:

Pasquale Braione, Blade Operation Manager, Vestas
Gian Luca Teodori, Head Of Maintenance Operations, ERG Renew
