Shell’s damaged icebreaker, the Fennica, went to Portland, Oregon, where workers repaired a meter-long gash in its hull that it suffered while attempting to travel north. Because the Fennica carries a mission-critical piece of safety equipment, Shell cannot drill into oil-bearing rock formations until it is fixed and returns to the Arctic.

Activists are hanging off the St John's bridge in Portland, Oregon, to stop the Fennica from reaching the Arctic where Shell plans to drill for oil.
