Vineyard Wind 1 is the first commercial-scale offshore wind farm in the country and the first of several US wind farm projects in DEME's portfolio.
DEME Offshore US is carrying out the transportation and installation of the monopile foundations, transition pieces, offshore substation, and scour protection, as well as the offshore substation foundation and platform.
Later, the company will also install the wind turbines.
As part of the installation process, Vineyard Wind has also deployed the offshore support vessel (OSV) Atlantic Oceanic and the Northstar Navigator to deploy a primary and secondary bubble curtain which is designed to absorb and dampen sound during foundation installation.
The hoses are placed on the seafloor around the monopile before being filled by compressed air. Once the hoses are inflated, the air escapes through the perforations and creates a barrier of bubbles that reduces noise.
With the recently signed agreement with Vineyard Wind and the work now being executed, ThayerMahan, a provider of seabed surveys and acoustic mitigation and monitoring, is the first American company to provide bubble curtain services to the US offshore wind industry.
