BP Discovers Gas Leak on Valhall

A gas leak was discovered on Valhall offshore Norway on January 12, 2004. The leak was discovered in connection with a planned maintenance job at around 6 pm. Most of the personnel were evacuated across the gangway to the quarters platform and production was shut down.

During a valve maintenance operation, free gas leaked out in connection with a nipple check. The detector system and the general platform alarm were activated from the central control room. Production was resumed at around 11.30 pm. The Petroleum Safety Authority's investigation team will go offshore to Valhall during the day in order to investigate the incident. In addition, BP has appointed an in-house investigation team. The police have decided not to visit the installation after all.
