Equinor, a Norwegian state-owned energy giant, has received the go-ahead from the country’s authorities to undertake plug and abandonment (P&A) activities in the North Sea off the coast of Norway with a semi-submersible rig managed by Odfjell Drilling, an offshore drilling contractor.

The Norwegian Ocean Industry Authority (Havtil) has granted Equinor consent to use the Deepsea Bollsta rig for permanent plugging and abandonment of wells 31/3-Q-21 and 31/2-X-23 at the Troll field in the northern part of the North Sea, where the water depth is 300-330 meters.
