Activists occupy oil rig in fight to prevent Arctic drilling --Environmental groups fear oil industry is not prepared for potentially catastrophic impact of oil spills in the Arctic 22 Apr 2011 The fight to stop the global oil industry exploring the pristine deep waters of the Arctic has been dubbed the new cold war, and early on Friday it escalated as environmental activists from 12 countries occupied the world's second largest rig on its way from Turkey to Greenland to drill among the icebergs. The protesters found the 52,000-tonne semi-submersible platform Leiv Eiriksson at around midnight, steaming due west at a stately six knots in the sea of Marmara, heading for the Dardanelle straits and the open Mediterranean.
