All Norwegian North Sea flights have been grounded due to bad weather, according to reports.
Energy giant Equinor is understood to have confirmed via its helipot website that all North Sea flights are cancelled today.
It had been reported earlier today that flights were delayed and some were cancelled due to heavy rain, high winds and thunder and lightning.
No UK North Sea flights are thought to be affected.
The cancellations affect the Ekofisk area, the Johan Sverdrup project and the Gullfaks and Statfjord fields.
Bristow Helicopters and Equinor have been contacted for comment.
