Construction crews have resumed attaching blades to Vineyard Wind's turbines off the coast of Nantucket. The work comes months after a blade broke off and sent debris and fiberglass into the water and onto beaches along the Cape and Islands.The federal agency overseeing the safety of the offshore wind farm said it's allowing turbine manufacturer GE Vernova and Vineyard Wind to install three more blades."The Bureau of Safety and Environmental Enforcement (BSEE) has reviewed detailed data and engineering documentation submitted by GE Vernova and Vineyard Wind 1, as well as the documentation from the certified verification agent (CVA), which is the independent third parties, regarding the installation of three turbine blades," Bureau of Safety and Environmental Enforcement said in a statement.
