File - In this March 22, 2014 file photo, a barge loaded with marine fuel oil sits partially submerged in the Houston Ship Channel. The owner of a tugboat that collided with a ship last month, dumping nearly 170,000 gallons of oil into the Houston Ship Channel, claims in court filings the ship was speeding and being operated in a reckless manner. Houston-based Kirby Inland Marine alleges in court documents filed earlier this month that the March 22 collision, which occurred after the ship struck a barge the tugboat had been pulling, was caused by gross negligence on the part of the ship’s owner, Liberia-based Sea Galaxy Marine. In its own court filings, Sea Galaxy says the collision was not its fault. (AP Photo/U.S. Coast Guard, PO3 Manda Emery, File)
