During the 18-week construction period, five steel jacket foundations have been installed at the site.

Nearly 200 workers and 12 construction and transport barges, tugboats, crew ships and monitoring vessels were employed at the project’s port facilities and the wind farm site.

Rhode Island Governor Gina M. Raimondo said: "Rhode Island is proud to be home to the nation’s first offshore wind farm, and we’re quickly becoming a center of innovation in this growing industry.

"With this project, we’re putting hundreds of our local workers to work at-sea and at our world-class ports to build a project that will help diversify Rhode Island’s energy mix and protect our environment."

Deepwater is now geared up to carry out turbine assembly and submarine cable installation work.

The company, along with General Electric (GE), is setting up a new temporary manufacturing facility at the Port of Providence for the assembly of turbine components.

GE is supplying the 6MW Haliade 150 offshore wind turbines for wind farm. It will install the electrical, mechanical, and safety equipment within the bottom tower sections in the next six months.

Submarine cable installation at the project will start in spring 2016, and five offshore wind turbines will be built the summer of 2016.

The project is expected to become operational in the fourth quarter of next year.

Meanwhile, Deepwater is proposing a new offshore wind farm and two new battery energy storage systems in a bid to meet growing energy demand in South Fork, the US.
