Crewmembers of Coast Guard Marine Safety Office Houston-Galveston are investigating the collision between the freight ship Napoleon and a tugboat with four barges in the Houston Ship Channel Monday night. A Coast Guard watchstander at Vessel Traffic Service Houston received the report of the collision via the pilot aboard the Napolean at approximately 10:40 p.m. According to the report the collision occurred while the Napolean attempted to over take the tug Jonathan Thomas, near buoy number 54, while heading out bound in the Houston Ship Channel near Redfish Bar in Galveston Bay. The collision caused the Jonathan Thomas's tow line to brake; setting the barges adrift, injuring one crewmen and damaging one barge and the tug.
