Ship-tracking company says that US Gulf Coast LNG and oil exports were zero on Sunday as a result of the freeze.

Vortexa, a ship tracking service, reported that exports of liquefied gas and crude oil from U.S. Gulf Coast ports fell to zero on Sunday, before resuming on Monday after a major winter storm hit the nation. A recent Arctic blast has pounded the United States, straining power grids and energy infrastructure. According to some estimates, up to 2 million barrels of oil per day were shut down over the weekend because of the cold weather.

Samantha Santa Maria Hartke, Vortexa's head of market research, explained that port closures were enacted to "prevent incidents" and "minimize congestion". This resulted in a reduction in exports. As ports reopened, exports rose on Monday, with volumes above normal seasonal levels.

Vortexa data revealed that crude oil exports were around 4.2 millions bpd in the morning on Saturday. They dropped to zero by Sunday, before rising to 4.4million bpd at noon on Monday.

On Sunday, LNG exports dropped from 159 metric tonnes per year (mtpa), to zero. The data revealed that it?rose to 83.1 mtpa by Monday.

Vortexa reported that exports of liquefied petroleum gas (such as propane and butane) fell 75% from Saturday to Sunday to 739.454 bpd.
