INCIDENT LOCATION: The tug and barge grounded on the south side of Ukolnoi Island, which is located approximately 206 miles east-northeast of Dutch Harbor and 40 miles east of Cold Bay, AK (Lat/Long: 55.200,

TIME/DATE OF SPILL: The tug and barge grounded at approximately 9:00 p.m. November 13, 2012. This is a potential spill incident; no release of fuel or lube products has been observed at this time from the grounded vessels. The grounding was reported to the U.S. Coast Guard at approximately 10:00 p.m. and ADEC was notified at approximately 11:00 p.m. November 13, 2012.

TYPE/AMOUNT OF PRODUCT SPILLED: No spill has occurred. The tug Polar Wind has 18,500 gallons of diesel fuel in its internal tanks. The barge Unimak Trader has 5,000 gallons on-deck fuel stores for the crane, fork-lift and generators located on the deck. The barge has no internal fuel storage tanks and no drums are on board. Operational quantities of hydraulic and lubricating oils remain on both vessels.

CAUSE OF SPILL: The tug and barge were transiting from Sand Point to Dutch Harbor when they grounded. Investigation is ongoing by USCG.

SOURCE CONTROL: No spill has occurred. The tug Polar Wind is a 78-foot long by 30-foot breadth vessel. The barge Unimak Trader is loaded with a crane, fork-lift, two generators and 90 refrigeration containers; thirty are operational and contains over 1,475,000 lbs of frozen seafood products and 60 containers are empty.

RESPONSE ACTION: The five crew members were rescued from the vessel by USCG. The crew had no reported injuries. A unified command has been formed with Northland Services, USCG and ADEC. Multiple over flights are scheduled to evaluate the condition of the tug and barge. Northland contracted Alaska Chadux to mitigate any potential pollution threats, and Global Diving and Salvage to provide incident management. Two over flights conducted yesterday verified that both vessels remain intact and stable. No sheen or evidence of pollution was visible. An initial assessment team is being coordinated to visit the grounding site as soon as weather permits. A team is currently drafting a plan to lighter fuel from the vessels to mitigate pollution threat. Vessels are transiting to the area to offload the shipping containers from the barge. Offloading is scheduled for the middle of next week.
