The 122 meter long, 5712 dwt cargo vessel Levant Horizon ran aground on the Tagus River off Oieras, Portugal. The vessel had departed from Lisbon when it veered off the fairway and ran into shallow water. Unable to free itself, the Levant Horizon requested assistance.  Two tugs arrived on scene and several hours later with the rising tide the Levant Horizon was successfully refloated. The vessels proceeded to Lisbon for inspection. No reports of injuries, damage or pollution released.
