Greenpeace International has sent out a ship 'Rainbow Warrior'on Monday to confront the Russian Oil tanker bringing the first oil produced at a new Russian offshore platform in the Arctic Circle to Rotterdam. The oil was drilled at the Prirazlomnaya platform, an offshore rig owned by Russian energy giant Gazprom and the site of Greenpeace's protest last September. The ship sailed from the port of Rotterdam at 12:40 Dutch time (13:40 GMT), told AFP Saliz Patrick, an environmental activist organization on board the ship. The ship is expected to make contact in a day or two with the Russian tanker 'Mikhail Ulyanov', which is heading to Rotterdam.
