Two of Louisiana’s main ports, New Orleans and Baton Rouge, reopened late on Wednesday, according to the U.S. Coast Guard. They joined the already functional terminals of Panama City, Biloxi, Mobile, Pascagoula, Bienville, Beaumont, Cameron, Lake Charles, Port Arthur, Sabine, Port Allen, Baton Rouge, Plaquemines, St Bernard, Berwick, Port Allen and New Iberia.
The Mississippi River also reopened on Thursday with restrictions from the Southwest Pass through New Orleans for daylight hours only, a spokesperson said.
But critical ports that act as oil hubs for handling the up to 1.8 million barrels per day (bpd) of crude produced at the U.S. side of the Gulf of Mexico remained shut.
The Louisiana Offshore Oil Port (LOOP), which is the largest privately owned crude export and import terminal in the United States; Port Fourchon, the Port of Houma and Southwest Pass remained shut on Thursday, according to the Coast Guard.
A National Oceanic and Atmospheric Administration survey showed on Thursday that Port Fourchon waterways had no major obstructions, a port official said.
Even after the port re-openings, the Valero St. Charles, Shell Norco, Marathon Garyville and Exxon Baton Rouge refineries in Louisiana remained restricted from oil and products supplies from the south via ship and barge, respectively, because of navigation limitations west of New Orleans.
They also continued dealing with power issues. Only the Exxon refinery has sufficient electricity to begin restarting. The other three wait for power to be restored, the companies have said.
A growing bottleneck of tankers waiting to discharge crude imports for refineries in Louisiana or to load refined products for exports has been growing around the state’s ports since the storm passed, according to vessel monitoring services.
