NEW YORK, Sept 3 (Reuters) - Several key refineries began restarting over the weekend after Hurricane Harvey slammed into the U.S. Gulf Coast energy hub and crippled their operations, but gasoline prices remained near two-year highs amid fears of shortages.
The storm took down a quarter of U.S. oil refining capacity and lifted average gasoline prices by more than 17.5 cents since Aug. 23.
On Saturday, ExxonMobil Corp began restarting the country's second-largest oil refinery, the 560,500 barrels per day (bpd) Baytown, Texas, unit, while Phillips 66 said it was working to resume operations at its 247,000 bpd Sweeny refinery and at its Beaumont oil and fuels terminal.
The restarts followed an announcement from Valero Energy Corp on Friday that it was increasing production at its Corpus Christi, Texas-area refineries.
The hurricane battered Texas before weakening to a tropical storm and inundated the region with torrential rains and flooding.
Some pipelines also restarted over the weekend, assuaging worries over the ability of refineries to get the crude oil they need to operate. Magellan Midstream Partners said it had resumed operations on Friday on its BridgeTex and Longhorn crude oil pipelines, which transport around 675,000 bpd of West Texas crude to East Houston.
Still, the majority of Texas ports remained closed to large vessels, limiting discharge of imported crude, and the Colonial Pipeline, which hauls more than 3 million bpd of refined products including gasoline, diesel and jet fuel from the Gulf Coast to the populous U.S. Northeast was also partially closed.
