12:00 - 13:30 The O&M impact on LCOE – How to get costs down?
O&M & logistics  
Onshore      Offshore    

Room: Montparnasse

This session shall focus on the challenge of reducing the Cost of Energy from wind parks through intelligent O&M.
What can be done from a Life Cycle perspective to ensure the O&M costs are minimised in respect to the highest possible RoI for investors?

The session will be devided in two parts: the first part will feature five presentations about opportunities and practical solutions for O&M cost reductions; in the second part four leading wind turbine manufacturers will share their experiences and outline their strategy to achieve cost reductions in O&M .

Please note that the session will be extended by 15 minutes and will therefore finish at 13:45 instead of 13:30.

Learning objectives

  • Be able to identify the Total Cost of Ownership for a Windfarm
  • Enable the attendees to suggest cost improvements at different project stages
  • Enable Attendees to verify and measure the impact of suggested improvements
  • Create understanding of a common industry reporting tool for failure rates
  • Learn about O&M challenges from leading wind turbine manufacturers

Presenter's biography

Biographies are supplied directly by presenters at EWEA 2015 and are published here unedited

Thomas Boehme is a Chartered Engineer with PhD (in marine renewables) and MBA degrees who has worked in the wind industry for 15 years. His experience includes planning, construction and operation of wind farms across the P.R. China and technical advice for offshore wind farms. He was project manager for / editor of offshore substation standard DNV-OS-J201 and subsea power cable guideline DNV-RP-J301. He currently reviews asset management practices in the energy sector, particularly offshore wind, to help customers align with ISO 55000.


Asset management - When will wind energy begin to realise value?


Large onshore and offshore wind farms may have been in operation for more than a decade, yet the idea of Asset Management (AM) has not yet permeated the wind industry. Grown from grassroots movements in the 1980s, persons involved in wind energy are often technically minded and view the 20-year generation period simply as “operation and maintenance”. Asset management, on the other hand, reaches much further and includes all the aspects that owners / operators should actually be doing (but frequently forget about).


“Asset management”, in brief, is a coordinated activity of an organisation to realise value from assets. The presentation provides insights into the key aspects of successful asset management and the AM system really needed, including AM strategy and objectives. DNV GL has worked in onshore and offshore wind farms and non-wind generation plants to assess the status of asset management and to improve the management. Common themes identified will be presented including actionable advice for stakeholders of small to large wind farms.

Main body of abstract

Traditionally focussed on maintaining a specific availability for the turbines and, if at all defined, for the collection and transmission assets (including cables and substations) and auxiliary infrastructure, owners and operators of wind farms are yet to embrace a holistic view of asset management beyond execution of minimum inspection and maintenance programmes.
Other industry sectors such as conventional generation, onshore transmission and offshore oil & gas have long tended to work to BSI PAS 55:2008 and are now switching to the ISO 55000 series of asset management standards published in 2014. At present, many wind farm owners and operators are stuck in outdated approaches, leading to a lack of control and limiting the understanding of what would be required to improve performance and value.
Although largely kept under the rug, common themes for action are emerging and will be explained in the presentation. For example, failure to comply with regulations, insufficient risk and contingency management and lack of linking technical and financial results will be explored. Furthermore, wind assets will be evaluated against Institute of Asset Management (IAM) benchmarks as well as performance from related sectors. Those in charge of the assets should take note to rectify the situation in time and begin to realise more value from their assets.


Appropriate asset management (which on a lower level includes the “hands on” monitoring, inspection and maintenance work) can significantly improve through application of sound management practices. The presentation will point out the key ingredients for successful asset management and how to get to (at least) the low hanging fruit.

Learning objectives
Frequently asked questions such as the following will be answered:
- “My assets are still in warranty and we are following the OEM’s recommendations. Is that not enough?”
- “Risk-based inspection & maintenance is the most advanced method for maintaining our assets, isn’t it? Can asset management add anything?”
- Do I need certification to ISO 55001?
