Avangrid has awarded TDI-Brooks a shallow water geotechnical site investigation survey at block OCS-A-0508 also known as Kitty Hawk Wind. The data collected will inform the design of the export cable and inter-array packages.
The scope of work includes utilizing a TDI-Brooks’ owned Datum Neptune 5K (pCPT) at 155 sites and a newly-designed TDI-Brooks pneumatic vibracorer (pVC) at 80 sites. The pVC is a light weight (4,600-lb in air), high power vibracorer and can be used for cores up to 6-m in length (and down to 9-m or 12-m with frame extension). Upon completion of the geotechnical vibracoring, all samples are sent to the TDI-Brooks’ geotechnical and environmental laboratories in College Station, Texas for testing. TDI-Brooks operates from a local port off Bridgeport, CT and plans to utilise the RV Marcelle Bordelon. The fieldwork is expected to be completed by mid-July.
The purpose of the project is to develop a commercial-scale, offshore wind energy facility in Commercial Lease OCS-A 0508, with up to 69 total wind turbine generators, an offshore substation, inter-array cables, an onshore substation, and up to two transmission cables making landfall in Virginia Beach, Virginia, and connecting to the Pennsylvania-New Jersey-Maryland (PJM) Interconnection energy grid.
