In what could signify a crossroads for the offshore wind industry, E.ON has internalised the O&M of offshore wind turbines at Scroby Sands. I spoke recently with Scroby Sands’ Operations Manager Keith Cooke about it, who told me the warranty period for these turbines was coming to an end, and instead of renewing the warranty, they decided to take on the maintenance themselves.
Of course, there are implications of taking on maintenance in this way. There’s a lot to learn and we, as O&M partners to the offshore wind industry, can provide a lot of value and have an important role to play. Continue reading
The Crown Estate has recently released its report focusing on how jack-up vessels can help bring down costs in the maintenance of offshore wind turbines.
The report, ‘Jack-up vessel optimisation’, studies the significant potential in cost reduction through sharing arrangements and closer cooperation between windfarm owners.
The report can be downloaded from Crown Estate’s website.
It points to evidence of significant production downtime due to maintenance planning and implementation and claims that revenues could be increased by as much as GBP 110 million across currently operational windfarms in the UK.
Even though the report is based on the UK offshore wind market, it is valuable reading for the industry as a whole, particularly within a wider European perspective.
I was very interested to see the three specific recommendations for progressing the concept of a ‘flexible charter club’.
This report also sheds new light on some of the findings in an O&M report commissioned by this site, Offshore Wind O&M, in particular related to the sometimes insurmountable costs of emergency repairs to single wind turbines.
Operations and maintenance in offshore wind is still an underdeveloped market and this report makes a welcome contribution to improving the market’s understanding of the key issues. This is something I have spoken about before and I’m pleased to see the increasing focus on the issue.
When considering maintenance issues in the offshore wind industry, it is important to look beyond just the offshore wind turbines themselves. Not only should wind farm owners and operators consider their equipment and balance of plant, but they need to use data from surveys and inspections in order to create a workable maintenance plan.
