(Adds vessel traffic resumption, production shut)
HOUSTON, Oct 8 (Reuters) - Some oil ports, producers and refiners in Louisiana, Mississippi and Alabama that shut facilities ahead of Hurricane Nate were on Sunday planning reopenings as the the storm moved inland, away from most energy infrastructure on the U.S. Gulf Coast.
The storm, which weakened to a tropical depression and was moving inland toward Alabama and Tennessee, killed 30 people in Central America before speeding across the central U.S. Gulf of Mexico, where more than 90 percent of oil output remained shut on Sunday.
Oil producer Chevron Corp on Sunday began to redeploy personnel, assess facilities and restore oil output at the Gulf of Mexico, including platforms, pipelines and two terminals shut ahead of Nate, the firm said in a statement.
The company also said it was assessing the impact of Nate on its 340,000-barrel-per-day Pascagoula refinery in Mississippi. Energy intelligence service Genscape said the firm shut the facility on Saturday.
Nate has forced the closure of more than triple the volume of Gulf offshore crude production than Hurricane Harvey did from late August to early September with 92.6 percent of total oil output shut, according to the Bureau of Safety and Environmental Enforcement (BSEE).
About 1.62 million bpd of oil and 2.5 billion cubic feet per day of natural gas output remained shut on Sunday at 298 evacuated offshore platforms, almost unchanged from Saturday numbers, the BSEE said.
Vessel traffic at New Orleans resumed on Sunday afternoon, according to the U.S. Coast Guard, while the port reopened under restrictions, only allowing tows and barges. The Port Association of Louisiana expects normal operations by Monday after surveys are completed.
The port of Mobile in Alabama remained closed on Sunday under condition Zulu, meaning all facilities and vessel traffic were shut.
About 18 oil tankers were sheltered on Sunday morning along the Mississippi River near New Orleans, half of them loaded with crude or refined products, as port authorities established a safety zone to protect vessels from hazards from severe weather, according to Reuters vessel tracking data.
In Mobile, Alabama, two tankers were near the port, according to the Reuters data.
Several cruise ships were also waiting for the vessel traffic to be reopened by the U.S. Coast Guard to approach New Orleans ports, where they would disembark passengers, the Ports Association of Louisiana added.
Phillips 66's 247,000-barrel-per day Alliance refinery and Valero's 125,000-bpd Meraux refinery, both in Louisiana, were reported undamaged after the passage of Nate, according to sources familiar with their operations.
Alliance may restart some units on Sunday but may not resume production until midweek because of the limited availability of crude oil at the U.S. Gulf, the sources said.
Phillips 66 said the firm had no update on the status of the refinery on Sunday morning. Valero did not immediately respond to a request for comment about Meraux, which was not shut during the storm.
The status of PBF Energy Inc's Chalmette refinery in Louisiana is unclear. The company did not respond to requests for comment on their operations.
