To get Vineyard Wind done, developers are turning to vehicles such as the Sea Installer, which arrived in Salem in early August. Owned by the Danish firm DEME Group, the vessel is one of the few on the planet capable of installing GE Haliade-X wind turbines that are the size of a skyscraper into the ocean floor.

Measuring more than 430 feet in length and 150 feet wide, Sea Installer is a “jack up” vessel that lifts itself out of the water on legs more than 300 feet long. Once elevated, the vessel becomes a platform where an immense crane, capable of lifting more than 1,600 tons, can install the tower sections, nacelle, and blades for each turbine.
