Picture of Sim yesterday morning on the rig

It’s five in the morning Greenland time and the last few hours have been quite insane. Last night, with the Espy pitching and rocking, and cups flying all over the place, we knew we had to get Timo, Meteusz, Sim and Jens off the rig. The worst of the Arctic weather was closing in, and their tiny tents were not going to be enough to keep them safe.

Our four climbers have spent the night in sub-zero temperatures, hanging off the bottom of Cairn's Arctic oil rig - the Stena Don. While we're attached to the rig, Cairn Energy can't continue their reckless drilling.

In the last couple of hours, we've received this footage from the Esperanza from this morning's daring occupation of the Stena Don, the oil rig operated by Cairn Energy. It shows just what an amazing feat the guys and gals there have pulled off, not least evading the Danish navy and scaling the oil rig legs.

Campaigners have evaded a huge military security operation to scale a controversial oil rig in the freezing seas off Greenland. At dawn this morning four expert climbers in inflatable speedboats dodged Danish Navy commandos before climbing up the inside of the rig and hanging from it in tents suspended from ropes, halting its drilling operation (video and stills available soon).
