The Arctic Challenger left Puget Sound's Bellingham Bay Wednesday night and arrived at a deep-water anchorage near Anacortes, Wash., Thursday morning. The barge is part of Shell Oil’s fleet of vessels aimed at exploring the Arctic Ocean for oil.

The Arctic Challenger’s oil-spill containment system failed its first field test off Anacortes in September. Since then, Shell has rebuilt a 20-foot oil-containment dome that was “crushed like a beer can” in the first test.

In addition to the containment dome, Shell's Arctic oil-spill response plans include using drilling mud, shear rams and a capping stack to block the flow of oil from a blowout and fire and chemical dispersants for oil that reaches the surface.
