The oil spill was discovered during the loading of oil from the Statfjord A platform to the tanker "Hilda Knutsen" via the OLS B loading buoy, which is located between Statfjord A and Statfjord B.
Loading to the tanker has stopped and supply to the pipe and loading system from Statfjord A has been closed. Production at Statfjord A is operating normally.
The leak is located in a flange in the loading hose. It is also too early to say how much oil has leaked.
The stand-by vessel with oil spill response equipment and the anchor handling vessel, equipped with a ROV, are at the location. A SAR helicopter is also assisting with monitoring the spill.
The relevant authorities have been notified.
