Catch the box! OPEN FLOOR DISCUSSION

Streamlining And Fine Tuning Your Predictive Maintenance Regime To Avoid Unexpected Costs

How many times have you heard colleagues and peers complaining about lack of knowledge and data sharing in the Wind industry? And, how many times did you all agree that the ultimate goal is to provide energy at affordable prices by bringing down O&M costs through preventative maintenance?

This session has been designed for audience participation and knowledge sharing with no excuses! Instead of slowly passing around a stick microphone, simply throw the soft catchbox to the first person in the room who’s meeting your eyes!

Delegates are encouraged to come along with ideas, comments and provocative questions for their peers. This is a self-moderated session so there won’t be such thing as hiding in corners!

13:45

Improving Performance Through Calculations And Loads Of Core Drivetrain Components

  • Calculations based on turbine production and how much lifetime has been consumed

  • Developing a service to calculate how long their turbines have left to operate and what can be done to extend their working lives

  • Looking specifically at the gearbox and bearing in order to calculate the earliest point of cracks and problems occurring in components

  • Simulating the outcome of different solutions — such as replacing a part, re-rating the turbine through operations, or making an oil change

  • Giving the owner valuable information on which they can they can base their decision

14:15

Emulation And Measurement Of Wind Turbine Power Converter Junction Temperature

  • Background to why we are doing the work (failure rates of power converters in wind turbines)
  • Outline of experimental work into measuring the junction temperature using IR sensors
  • Work into emulation of wind turbine operational profiles in the laboratory
  • Outline of our collaboration with a power electronics testing company on this project and future ideas

16:15

The Role Of Asset Management In Reducing O&M Costs Whilst Maximizing Profitability And Prolonging A Fleet’s Lifetime 

  • Extend lead time by planning ahead

  • Optimising spare parts replacement

  • Understand how extended lead-time translates to substantial savings

  • What information do you need from your drivetrain to make the right choices for your fleet?

Michael Wilkinson, Service Line Leader Asset Operations And Management, DNV GL 

16:45

Speed Networking

Realising the importance of connecting with your peers, we organised a moderated networking session where delegates are prompted to meet others in brief 3-minute rounds. The moderator will be keeping track of time and announcing participants when to switch partners.

Make sure you bring lots of business cards along with you!
