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.
-----Update 8 October 3.15 p.m.
Preliminary assessments indicate that the spill is within the range of 40 cubic metres of oil.
Further assessment and investigations will uncover the scope and causes in more detail.
