OEM CASE STUDY

Preventative vs. Reactive Maintenance: When Does It Become Too Late To Repair Or Replace?

  • Moving towards the end of a blade’s lifetime: making sense of numbers by looking at the turbine components

  • Increasing the monitoring activity for informed and cost-effective decisions on your blades

  • Why do regular maintenance and inspection campaigns become more and more essential towards the end of a blade’s lifetime?

CASE STUDY

How Inspection Data Facilitates Discussions Between OEM And Utilities At Key Milestones For A Wind Farm's Life

  • Working with data from a range of inspection sources (ground based, drone, rope etc)
  • Mapping blades defects to wear and tear documentation
  • Managing the process from Inspections to repairs using standardised workflows
  • Identifying significant opportunities for cost savings in ongoing O&M

HIGH FREQUENCY TALKS

What’s Coming Up Next? What Does The Industry Want For The Next Blade Generation?

Blade technology is at the core of wind energy advancement and it’s constantly evolving into something more and more sophisticated. However, due to OEMs rightfully protecting their intellectual property, it is difficult to share specific useful information across the industry, which would instead benefit all the key stakeholders.

During this session, each delegate will have the chance to express their thoughts, concerns, ideas and solutions for the future - both  anonymously  and in  written form  (5 minutes). The moderator will then read out these comments, revealing what delegates are hoping to see in the next generation of blades. The debate will then be opened up to the rest of the room, making this the perfect occasion to take a real step forward - together.

Blade Maintenance Powered By Innovation

  • Optimized conditions for epoxy repairs to wind turbine blades   - the benefits of creating a protected environment on blade access platforms   
  • Demonstrate how savings are possible through near real-time reporting of repair progress via GEV tablet mounted Intuitive Repair and Inspection System
  • Reducing inspection times by using a remote camera system
  • Ground Based Habitat - carrying out repairs in the field but in the comfort of a factory-like environment
  • The future of turbine blade maintenance - how to predict cash flow through monitored preventative maintenance

ROUNDTABLE DISCUSSIONS

15:15 Delegates will select one topic from either the 'technical' stream, or the 'strategic' stream below. The audience will then breakout into smaller groups based on their topic of choice and engage in in-depth discussions.This is a great opportunity to share ideas with like-minded peers in an intimate setting. 

THE TECHNICAL STREAM

1. How to minimise downtime and lower repair costs in severe blade damage cases

Andrew Bellamy, Rotor Blade Specialist, Ocean Breeze

2. Gaining a technical know-how on minimising leading edge erosion

 Christian Bak, Senior Scientist, DTU 


THE STRATEGIC STREAM

1. Utilities’ close door roundtable: measuring up OEMs’ commitment and sharing know-how on blade maintenance

Rui Menenes, O&M Area Manager, IberWind

2.  How to safely and economically push blade life expectancy beyond 20 years

Romaric Thiebaut, Specialist - Technical Lead, Vestas
