The Kulluk accident occurred weeks after Shell* made the first foray into drilling in U.S. Arctic waters in two decades, an effort forestalled by equipment troubles and advancing ice.

'The Coast Guard concluded that Shell made an ill-advised decision to tow its drill rig away from the state, a 1,700-nautical-mile journey across the northern Gulf of Alaska in the final days of December 2012, in part to avoid millions of dollars in tax liability.

The Coast Guard detailed the missteps aboard its tow ship, the Aiviq, and how its fuel tanks were improperly configured, leading to contamination, most likely by seawater. According to the Coast Guard report, the Aiviq tow master sent an email to the Kulluk tow master before the journey: "To be blunt I believe that this length of tow, at this time of year, in this location, with our current routing guarantees an ass kicking."'
