Investigation report following the fire on Åsgard B on 15 October 2005

On Saturday, 15 October 2005, a fire broke out in the heat exchanger in the main power generator at Åsgard B on Haltenbanken. The Petroleum Safety Authority Norway has investigated the incident. The cause of the fire was an oil leak in one of the pipe coils in the heat exchanger.

On 15 October 2005 at 11:45 a.m. the Petroleum Safety Authority Norway was notified by Statoil of a fire on Åsgard B. The oil ignited after the generator shut down. The fire-fighting and contingency measures functioned satisfactorily. The fire did not result in any personal injury and only minor material damage.

Through our investigation we have, inter alia, identified the following nonconformities in relation to the regulatory requirements:

  • The fire in the area was not detected by the flame detectors, but only by manual observation.

  • The northern and western surfaces of the exhaust duct could not be reached with the available manual fire-fighting equipment. Six lengths of hose had to be spliced together to reach the nearest hydrant in M 70, and a suitable position for the mobile fire monitor had to be improvised.

  • The maintenance program has not been adequately designed to compensate for weaknesses in the design and construction. Damage to the heat exchanger has not occurred suddenly, but has developed over time as a result of faults in the design/construction, as well as external influence from heat and vibration in the exhaust duct.


We submitted our investigation report to Statoil on 3 February 2006, and held a meeting with the company on 23 March to review issues including measures implemented and planned after this fire.
