The 33,609 dwt Argent Cosmos ran aground in the morning hours of June 6 after it lost the use of a fuel pump on the Columbia River in the vicinity of Skamokawa, Washington.
There were no reports of pollution in the river, flooding aboard the vessel or injuries to crewmembers, according to data provided by the United States Coast Guard (USCG).
The coast guard was notified when the vessel began incident notifications. An aircrew aboard an MH-60 Jayhawk helicopter from Sector Columbia River conducted an over flight at 9 a.m. and reported no signs of pollution.
The Panama-flagged tanker is loaded with 1.63 million gallons of ethanol and 6.65 million gallons of monoethylene glycol. It also has 458,074 gallons of high-sulfur oil and 99,064 gallons of low-sulfur oil aboard.
USCG said that the vessel was heading outbound after finishing a port call at Longview, Washington. Two tugs are on scene to assist Argent Cosmos as the water rises with the incoming tide.
Capt. Bill Timmons, commander Coast Guard Sector Columbia River and captain of the port has placed a no-movement order on the vessel until Coast Guard inspectors ensure the safety of the environment and the crew aboard.
