Equinor has secured Norwegian consent to use Deepsea Bollsta for drilling, completion, temporary plugging and workover on Johan Sverdrup, following a rig contract extension tied to an eight-well program.
Equinor completed its probe into the 23 September 2025 well-control event on Deepsea Bollsta at Troll, detailing a short gas release during casing cutting and follow-up measures.
Odfjell Drilling has acquired the harsh-environment rig Deepsea Bollsta from Northern Ocean, will rename it Deepsea Bergen in 2026, and has boosted backlog and refinanced with new loans and a bond.
Odfjell Drilling has agreed to acquire the Deepsea Bollsta from Northern Ocean in a $480 million transaction. The rig adds $355 million to the company’s firm backlog and continues its long-term programme with Equinor.
Equinor has extended Northern Ocean’s Deepsea Bollsta contract by five months for continued drilling on Norway’s Johan Sverdrup field.
