Most of the jet fuel onboard the U.S.-flagged tanker Stena Immaculate that was hit by a container ship in a collision off Britain's coast remains contained and only two of the vessel's 18 fuel tanks have leaked,

"Both vessels have sustained significant damage in the impact of the collision and the subsequent fire," Solong's Hamburg-based owner, Ernst Russ, said in a statement. "13 of the 14 Solong crew members have been brought safely shore. Efforts to locate the missing crew member are ongoing."

The tanker that was hit at anchor off the coast of England in the North Sea was under contract by Military Sealift Command in support of the Defense Logistics Agency, USNI News has learned. The U.S.-flagged MV Stena Immaculate was at anchor when Portugeuse-flagged container ship MV Solong struck the tanker at about 5:48 a.
