Not too long after the first components for the Vineyard Wind project were delivered by UHL Felicity, DEME’s offshore installation behemoth Orion has started the installation of the first monopiles and transition pieces. Orion will work with a team of ships throughout the summer installing 62 foundations in the wind development area.

“We can finally say it – as of today, there is ‘steel in the water,’” said Vineyard Wind CEO Klaus S. Moeller. “Over the next few months, we’ll be working hand in glove with the Building Trades and our contractors to ensure the work is done safely and efficiently. I want to thank all of our stakeholders and the entire Vineyard Wind team for this remarkable achievement on this first in the nation project.”

“After receiving the first turbine components in New Bedford last week, Avangrid’s Vineyard Wind 1 project has achieved another historic milestone for offshore wind in the United States as we begin foundation installation,” said Avangrid CEO Pedro Azagra. “We’re proud that local union piledrivers are playing a critical role in the installation of the monopiles and transition pieces in the project area as we pioneer this new American industry.”

In addition to the existing crew, the vessel Orion is utilising local union piledrivers. The piledrivers received special training to begin this scope of work. As tradespeople gain additional experience in the offshore wind industry, greater employment opportunities will be created in the trades.

Vessels on the job

As part of the installation process, Vineyard Wind, a joint venture between AVANGRID and Copenhagen Infrastructure Partners (CIP), has also deployed the OSV Atlantic Oceanic and the Northstar Navigator to deploy a primary and secondary bubble curtain.

A bubble curtain, which is comprised of large, perforated hoses and specialised air compressors, is designed to absorb and dampen sound during foundation installation. The hoses are placed on the seafloor around the monopile before being filled by compress air. Once the hoses are inflated, the air escapes through the perforations and creates a barrier of bubbles that reduce noise.

Three local fishing vessels, the Torbay, Socatean and the Kathryn Marie, will be onsite to serve as safety and communication sentries.

The project is also deploying a Passive Acoustic Monitoring (PAM) system comprised of fixed buoys. Up to four PAMs will be used for real-time underwater acoustic monitoring during pile driving to characterise the presence of marine mammals by detecting vocalisations. The buoys will be deployed and retrieved by the Beth Anne before mobilising to the next foundation location.

“We look forward cooperating with all stakeholders and US partners in the construction of this first large-scale offshore wind project in US waters, including the local union workers who will participate in the installation work under the project labor agreement,” said Sid Florey, President DEME Offshore US. “DEME Offshore has contracted with local US vessels and crews to be deployed for mitigation of noise emissions as well as marine mammal observations.”

An 800-megawatt project located 15 miles off the coast of Martha’s Vineyard, Vineyard Wind will generate electricity for more than 400,000 homes and businesses in the Commonwealth of Massachusetts, create 3,600 Full Time Equivalent (FTE) job years, save customers $1.4 billion over the first 20 years of operation, and is expected to reduce carbon emissions by more than 1.6 million metric tons per year, the equivalent of taking 325,000 cars off the road annually.
