GUAM – Coast Guard Sector Guam and Pacific Strike Team members continue to closely monitor various compartments aboard Guam Shipyard dry dock “Big Blue” for any further signs of oil as salvaging operations continue, Monday.

Coast Guard members, along with Guam Shipyard workers, worked throughout the weekend, successfully removing approximately 108,000 gallons of oil and oily wastewater from a machinery space aboard Big Blue, Sunday. Workers were able to safely reach the last known remaining fuel sources aboard the dry dock after the transfer lines were tested. This led to the removal of 100 gallons of lubricant oil from a lube oil tank and another 717 gallons of waste oil from a sludge tank.

Now that these tanks are confirmed empty, Guam Shipyard workers are moving forward to clean the diesel engine and internal pumping equipment which will aid in the salvage of the drydock.

Big Blue’s diesel tank, the largest known fuel source aboard the dry dock, was confirmed empty after the remaining fuel was transferred to the tugboat Marianas Voyager, Friday.

Underwater work includes dive operations to reestablish watertight integrity of spaces that are still submerged. Divers will be surveying the dry dock for stability and closing manifold covers as dewatering operations of other compartments continue.

To report any debris or signs of oil in the water around Big Blue, call the Sector Guam Command Center at (671)564-USCG.
