Ship traffic operations are back to normal along the Sabine-Neches Waterway, US, eight days after a tanker collision, according to a marine organisation.

The accident resulted in 11,000 barrels of spilled oil and had temporarily shut the channel that supplies crude to four US refineries, reports Reuters .

The waterway had been shut between 23-27 January while the damaged tanker blocked the waterway. After the tanker was removed, vessels faced significant restrictions including allowing only one ship at a time in portions of the channel to prevent spreading the spilled oil, according to the news agency.

The only limitation is a seven-mile stretch where ships must reduce their speed to avoid spreading oil remaining to be cleaned, according to the Sabine Pilots association.
