The offshore wind industry faces a well-known paradox. It needs wind to generate electricity, but too much wind makes it difficult to create the necessary infrastructure. Quite simply, lifting major components in high winds is one of the biggest issues facing offshore wind turbine installation. Over the years, thousands of days of installation time have been lost, leading to cost increases in the billions of Euros and huge project delays.

Offshore wind now accounts for about 7% of European renewable energy generation. Most of this new capacity has been built since 2015. Although the rate of growth has been slower than many expected or hoped, it is still a significant shift in the way Europe generates electricity. The change has been biggest in the UK, where offshore wind now generates about 5% of all its UK electricity demand.

As offshore wind turbine sizes grow rapidly, the technology needed to install and commission turbines is not following suit. This is a significant barrier to progress in the offshore wind industry and is continuing to make it difficult to reduce the levelised cost of energy.

The offshore wind industry has paid little attention to outage time. This claim is made by MAKE Consulting in a recently released report about offshore wind O&M in Northern Europe.

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.
