As we know that near orange county of California, an underwater oil pipe line ruptured which resulted in around 3000 gallons of oil spill. As per the findings it is suspected that line could have been damaged by a ship anchor. In this case, USCG is boarding each ship in the vicinity (Plenty of them) and checking their records if any of the ship dropped or dragged anchor on the line and caused a damage to the same. Though some company ship name is circulating on social media, but there is no utmost proof that those ships were actually involved in this disaster. It will take some time for USCG to figure out and completely clear the picture, if there is any involvement of ships.
