PROVIDENCE, R.I. — Workers at ProvPort have been unloading the 240-foot-long turbine blades that will ultimately be used for the nation's first offshore wind farm, off Block Island.

Deepwater Wind says dockworkers began unloading the 15 blades on Tuesday. They are scheduled to be brought to the Block Island Wind Farm site by boat in August.

The company says several other steps have been progressing as they work to complete the five-turbine wind farm.

A 6.5-mile cable that will connect the wind farm to Block Island has been installed. And a 17-mile cable that will connect Block Island with the mainland reached Block island last week.

Deepwater Wind says it will complete the cable connections between the wind turbines next month.
