VolturnUS 1:8 is a 65-foot-tall floating turbine prototype that is 1:8th the scale of a 6-megawatt (MW), 450-foot rotor diameter design. VolturnUS 1:8 the first grid-connected offshore wind turbine in the Americas. The patent-pending VolturnUS 1:8, was designed and built at UMaine, assembled at Cianbro’s facility in Brewer, successfully towed nearly 30 miles from Brewer by a Maine Maritime Academy tugboat, and anchored for testing off the coast of Castine, Maine in 90 ft of water.

The VolturnUS 1:8 was deployed in Castine, ME, for 18 months. On June 13, 2013, the turbine was energized and began delivering electricity through an undersea cable to the Central Maine Power electricity grid.

The VolturnUS 1:8 was towed down the Penobscot River from Cianbro’s facility in Brewer, ME, to Castine, ME, by Maine Maritime Academy.

The VolturnUS 1:8 was launched from Cianbro’s facility in Brewer, ME, on May 21, 2013. More than 2,000 people viewed the launch in person and online.

The VolturnUS 1:8 was deployed alongside DeepCLiDAR. DeepCLiDAR is an advanced metocean buoy outfitted with LIDAR, created with funding from the US Department of Energy and the Maine Technology Institute. DeepCLiDAR can be used in remote marine environments to provide high quality, low-cost offshore wind resource data, metocean monitoring, and ecological characterization capabilities. The system was developed in partnership with Dr. Neal Pettigrew of the UMaine Physical Oceanography Group, AWS Truepower, and NRG Renewable Systems.
