Abstract

In the coming decade, at least 15 commerical offshore wind projects are planned for deployment on the Mid-Atlantic Outer Continental Shelf (OCS) between Cape Cod, MA and Cape Hatteras, NC. This development will involve hundreds of utility-scale wind turbines with rotors spanning a swept circular area up to 220 m in diameter, and blade tips reaching elevations up to 250 m above mean sea level. These turbines and their foundation substructures must be designed to withstand extreme winds and waves during a 50-year return period, with strutural robustness expected for 500-year return period conditions. This presentation will review the offshore wind buildout on the U.S. East Coast, the governing design load cases imposed by winds and waves, and the challenges faced by metocean scientists, engineers, and regulators in ensuring that the unique features of tropical storm systems are properly addressed in adapting European offshore wind design practice, which evolved for the extratropical storm environment of the North Sea, to the Mid-Atlantic OCS.


Biography

George Hagerman is a Senior Project Scientist with the ODU Research Foundation, working at CCPO since January 2018. Prior to this, he was a research faculty member at Virginia Tech, where he served on the front-end engineering design team for Dominion Energy's offshore wind demonstration project, responsible for helping prepare work scopes and reviewing work products for its metocean design basis. Now named the Coastal Virginia Offshore Wind (CVOW) project, Dominion's two demonstration turbines are scheduled for installation in 2020, on a renewable energy research lease located 23 nautical miles off Virginia Beach. George has nearly 40 years' experience working on marine renewable energy systems, including offshore wind power, wave power, tidal stream power, and ocean thermal energy conversion. He has also served on the Virginia Intergovernmental Offshore Renewable Energy Task Force since it was established by the Minerals Management Service (now the Bureau of Ocean Energy Management) in 2009.
