Output at North Sea Gullfaks B platform shut after helicopter crash: Statoil

OSLO (Reuters) - Production at the Statoil-operated Gullfaks B platform in the North Sea is shut for an undetermined period following a helicopter crash in which 13 platform staff are presumed dead, a senior company official said. "Production is shut at Gullfaks B so that we can take care of the (platform) staff in the best way possible," Statoil's head of development and production in Norway, Arne Sigve Nylund, told a news conference. He did not say at what rate the platform was producing at when it shut down. Partners in the field include Austria's OMV and Norwegian state-owned firm Petoro.
