Equinor Begins $412M Troll Gas Subsea Project to Add 11bcm by 2028
EQNR•Equinor and partners will invest just over 4 billion Norwegian crowns ($412 million) in the Troll field’s TWIN subsea development to boost gas production by about 11 billion standard cubic meters. The third step of Troll Phase 3 is slated to begin output as early as 2028 to extend plateau production.
1. Project Investment and Partners
Equinor and its partners Petoro, Shell, TotalEnergies and ConocoPhillips have approved an investment of just over 4 billion Norwegian crowns (approximately $412 million) for the Troll gas field’s new subsea development. This funding covers design, drilling and installation of the TWIN subsea system.
2. TWIN Development Details
The TWIN project represents the third step of Troll Phase 3, targeting gas extraction from the Troll West reservoir. It is engineered to deliver around 11 billion standard cubic meters of additional gas to reinforce supply volumes.
3. Production Timeline and Capacity
Equinor aims to initiate production from the TWIN subsea development as early as 2028, extending high-yield operations from Troll A and the Kollsnes processing complex. The phased approach ensures continued output through at least 2030.
4. Strategic Cost and Execution Goals
In response to aging fields and rising costs, Equinor has set an ambition to halve subsea project costs and execution times. The company plans to develop six to eight subsea projects per year on the Norwegian Continental Shelf through 2035.
