Guam - As the U.S. Coast Guard continues its investigation into the cause of why the Shipyard's floating dry dock, Big Blue, became partially submerged, it has established a unified command with the Guam Environmental Protection Agency and the Shipyard to manage the recovery process. According to a media release from the Coast Guard, they've reviewed the Shipyard's finalized plans to recover Big Blue.
It outlines the shipyard's commitment to work with oil recovery contractor Gresco under the supervision of the Coast Guard and Guam EPA, to prevent pollution spills during salvage operations associated with the recovery. Company officials reported no signs of petroleum leaking from the dry dock's oil tanks after a team of divers conducted a survey of the vessel, and floating boom was deployed around the vessel as a precaution in case of a pollutant release, Tuesday.
It's estimated that a potential 83,000 gallons of wastewater, a mixture of oil or diesel with water, could be aboard Big Blue. However, soundings of the tanks are being conducted to ascertain the actual amount in each tank.
Salvage operations to remove all the wastewater from the vessel and re-float the dry dock are expected to proceed this week.
