On 27 May 2014, Greenpeace's ship, MV "Esperanza", took over Transocean Spitsbergen, oil rig of Statoil in the Barents Sea such that it became incapable of operating. After that, the manager of Greenpeace Norway Truls Gulowsen answered a phone interview, stating that "Five protesters left the rig by helicopter last night and three returned to a nearby Greenpeace ship." There were seven more protesters on the rig at the time, but the Norwegian police could not remove them immediately because the rig was a flag of convenience ship registered in the Marshall Islands and thus regarded as a ship in the open sea, as long as it did not begin drilling. On 29 May, however, the seven activists from Greenpeace were peacefully captured by Norwegian police on the rig. Soon after, according to Reuters, all the activists were set free without any fine. On 30 May, the Norwegian Coast Guard finally towed away "Esperanza", though in the morning Greenpeace submitted a plea on which more than 80,000 signatures to the Norwegian Environment Minister Tine Sundtoft in Oslo were written. Norwegian government and police reportedly allowed the coast guard to tow the Greenpeace ship.
