A spill of almost half a million gallons of crude oil on 23 January has forced oil-handling Port Arthur in Texas to close.
An AET tanker chartered by ExxonMobil leaked 450,000 gallons of crude oil into the surrounding waters after it collided with two barges, and as of 24 January only approximately 10% of the total amount of oil spilled has been removed by clean-up crews.
The Sabine Neches Waterway adjacent to Port Arthur has also been officially closed to all traffic.
We're not going to open the port until it's determined that vessels can pass through cleanly, safely and not cause further damage, a US Coast Guard spokesman said.
The ship, Eagle Otome, was carrying close to 600,000 gallons of crude oil to the oil major's Beaumont Refinery when it crashed.
The Eagle Otome's owners, Malaysia-based aframax operator AET, has said that 15 skimming vessels, 45,000 feet of boom, and 500 personnel for containment are already involved in cleaning operations.
