Greenpeace activists have stormed a floating oil rig in Russia's Pechora Sea, hundreds of miles from the nearest port, to protest oil drilling in the Arctic, AP quoted the environmental organization as saying on Friday. Six activists boarded the Prirazlomnaya platform in the early hours on Friday and remain on the rig, Greenpeace said in a statement. They set off in inflatable speedboats from their ship and scaled the platform with mooring lines. The activists, which include Greenpeace's chief Kumi Naidoo, did not face much resistance from oil workers and managed to put a banner on the rig, which says: "Don't kill the Arctic." Prirazlomnaya is owned and operated by a subsidiary of Russian energy giant Gazprom, which is pioneering Russia's oil drilling in the Arctic. The state-owned company installed the drilling platform there last year and is preparing to drill the first well. Naidoo told the AP that his teams are suspended from the platform's mooring lines. He said many of the platform's employees "have been very friendly, engaging in conversations with us, asking where we come from and offering us soup." Naidoo said the activists have been told by one of the platform employees that a coast guard helicopter is on its way to detain them. The platform is about 1,000 kilometers (620 miles) from the nearest port - Murmansk, a city on the extreme northwestern edge of the Russian mainland. Gazprom would not comment on Greenpeace action, but said it would issue a statement later. Greenpeace said that its activists have supplies to last "for an extended stay." Russian and international environmentalists have warned that drilling in the Russian Arctic could have disastrous consequences because of a lack of technology and infrastructure to deal with a possible spill in a remote region with massive icebergs and heavy storms. An AP investigation last year found that at least 1 percent of Russia's annual oil production, or 5 million tons, is spilled every year. A report by Greenpeace and World Wildlife Fund, issued last week, said that a spill from Prirazlomnaya could contaminate protected areas and nature reserves on the shore and islands within 20 hours, while emergency teams would take at least three days to reach the area. -- SPA
