Cable-laying operations for the inter-array cables are set to begin at the Vineyard Wind 1 offshore wind farm. The work, carried by Jan De Nul Group’s vessel Isaac Newton, will begin with array cable lines five and six. The Isaac Newton, a DP2 cable laying trenching support vessel, measures 453’x105’x24’ with a deadweight tonnage of 12,500 tons.
Vineyard Wind, a joint venture between Avangrid and Copenhagen Infrastructure Partners (CIP) noted the Isaac Newton will remain on-site until early October.
The C-Pioneer, an offshore supply ship (OSS), will be acting as a stationary support vessel, supporting cable-pulling activities for the inter-array cables.
The Adhemar De Saint-Venant will serve as the trenching support vessel, set to perform cable trenching and burial works.
The Seafarer will be operating around the activities as a safety vessel to monitor traffic and facilitate safe movement of fishing vessels, recreational craft, or other transiting vessels around the work sites and project vessels.
Jan De Nul and the TFKable Group-owned JDR will deliver almost 130 miles of 66 kV cables that will connect the project’s 62 GE Haliade-X turbines and transfer electricity to an offshore substation for transmission to the grid.
The Prysmian Group is supplying the export cable intended to deliver electricity to shore from the offshore substation.
Situated 15 miles off Martha's Vineyard, this project represents the inaugural commercial-scale offshore wind farm to secure construction approval within the U.S.
