The Coast Guard is continuing its investigation into an accident earlier today where a 793-foot tanker struck a pier on the west bank of the Mississippi River in Westwego, La. There were no reports of injuries ashore or on the Maltese-flagged tanker Tsunami. A Coast Guard helicopter overflight observed minor sheening in the area, possibly a result of damage to the S.T. Services pier. Drug and alcohol tests have been administered and the results are pending. The Tsunami, which was carrying an estimated 20 million gallons of sweet crude oil, reportedly has a 3-foot gash above the waterline along the hull's port side. There have been no reports of pollution from the vessel.
