Utility National Grid is to kick off the installation of a 20km submarine cable to connect the 30MW Block Island wind farm to the Rhode Island mainland.

“We have not been able to pull the cable ashore but we expect to start tomorrow,” a National Grid spokesman told reNEWS after rough seas halted recent work on the wire.

Crews in Narragansett will feed the cable through a conduit and into a land/sea transition vault. Once the cable is secured in the vault, the Big Max barge will begin the two week, 20-mile journey to Block Island, burying the cable at a target depth of 4 to 6 feet below the sea floor.

The overall wind farm construction “is moving along on schedule,” Deepwater Wind told reNEWS. “The export cable from Block Island was successfully pulled into jacket 1.”

On Block Island, National Grid took delivery of the first substation components and civil and foundation substation work is underway.

Liftboats Michael Eymard and Lacie Eymard continue to perform work at the foundations.

Deepwater plans to install five GE Haliade 150 6MW turbines this summer and start commercial operation in the fall.
