Statoil Chief Executive Helge Lund looks on at the offshore Kristin oil and gas platform in the North Sea, about 100 km (62 miles) east from Kristiansund, June 25, 2012. Norwegian oil workers announced a strike on Sunday, demanding higher wages and the right to early retirement. Norwegian gas and oil exports are not threatened for now by a strike by oil workers, the oil minister said on Monday and urged the parties involved to make the stoppage as short as possible. The strike, launched by about 700 offshore workers after negotiations between unions and the industry association broke down over a pension issue, has caused shutdowns of two fields offshore Norway.
