NO has the ONLY supertanker hub for the US.

Proof please.

[Knitting A Conundrum]

Not New Orleans, but Louisiana:

"The region is also home to America’s only supertanker port, the Louisiana Offshore Oil Port (LOOP). Located in the Gulf of Mexico just south of Fourchon, LOOP handles 800,000 barrels of crude oil each day, 12% of the U. S. supply of daily crude imports."

Not that it matters a lot but LOOP off loads some one million bbl/day of crude.

(Louisiana Offshore Oil Port) was organized in 1972 as a Delaware corporation and converted to a limited liability company in 1996. Ashland Inc., Marathon Ashland Pipe Line LLC, Murphy Oil Corporation, and Shell Oil Company are LOOP's owners.

The port facility is located in the Gulf of Mexico, eighteen miles south of Grand Isle, Louisiana, in 110 feet of water. LOOP is the only port in the U.S. capable of offloading deep draft tankers known as Ultra Large Crude Carriers (ULCC) and Very Large Crude Carriers (VLCC). Along with offloading crude from VLCC’s, LOOP also offloads smaller tankers.

Weather data from the LOOP facility .. Winds at some 31kts.
