Donjon Marine Co., Inc., a provider of multi-faceted marine services including marine salvage, heavy lift, dredging and related emergency response services, was contracted under a Basic Ordering Agreement (BOA) by the U.S. Coast Guard to provide emergency salvage services for two tugboats that sank on July 28, 2008 at a pier adjacent to the Schuylkill River near the Girard Point Bridge outside Philadelphia, PA. At the time of the sinking of the Scooby Doo and Big Boy, reportedly more than 2,000 gallons of petroleum based contaminants were released into the water. Divers have reduced the out flow from the tugs but due to the condition of the vessels, the flow cannot be stopped until the vessels are salvaged.
