Troll is around 65km west of Kollsnes in Hordaland County and is the largest gas discovery made in the North Sea.

The consent is an extended consent to use the controlled mud level method – formerly referred to as dual gradient drilling (DGD). 

The expected start-up is late September 2017. The activity is expected to last 75 days.

Songa Equinox is a semisubmersible drilling facility operated by Songa Offshore. The rig received an Acknowledgement of Compliance (AoC) on 20 November 2015.
