The Crown Estate leases the sea bed for offshore wind and provides a framework to sustain the UK’s leadership of the offshore wind market. It has commissioned this Towards Round 3: Progress in building the offshore wind supply chain analysis to help a new and rapidly growing industry understand the supply chain challenges that it faces and how they might be resolved. It provides an update to Towards Round 3: Building the Offshore Wind Supply Chain, published in May 2009, and is once again based on consultation with developers and feedback from suppliers in key areas.
