Chevron wishes they'd go away, but Greenpeace has succeeded in boarding the Stena Carron near Shetland Islands "and attached themselves to the ship's anchor chain."
Greenpeace said the ship had been on its way to the Lagavulin oil field, where it was scheduled to begin exploratory drilling.
''Chevron North Sea is appealing to Greenpeace to immediately stop their actions at the Stena Carron while it is going about its lawful business in Bressay Sound,'' the U.S.-based oil company said in a statement.
