In November, developer Deepwater Wind contracted Gulf Island Fabrication to construct jacket foundations for the demonstration project.
The foundations are being constructed at Gulf Island's facility in Houma, Louisiana. As part of Gulf Island's deal with Deepwater Wind, Rhode Island business Speciality Diving Services has been subcontracted to provide some components for the foundations.
Delivery of the 1,500 tonne jacket structures is due to take place in the summer of 2015. Block Island is located five kilometres off the Rhode Island coast, northeast US.
The foundations will be used to support five Alstom Haliade 6MW turbines, which are due to be installed in autumn 2015. The project is expected to be online in 2016.
