A Shell Oil offshore drilling rig ran aground in southern Alaska Monday, marking another in a long series of setbacks for the company's Arctic drilling development.
The Kulluk rig was on its way to maintenance in Puget Sound, Wash. when a severe storm hit and caused it to separate from a tow line.
As of Wednesday morning, there are no reports of spillage. The rig currently carries over 150,000 gallons of diesel fuel and other oil products.
