The Norwegian state player is still unsure, however, when full output can be resumed at the facility following the 17 May closure.

Statoil shut in the platform and evacuated non-essential personnel when an ROV inspection revealed a crater measuring 100 cubic metres at one of four seabed production templates at the field.

Following the initial shut-in on 17 May, it was closed again two days later after there were problems with the restart.
