Equinor-led TWIN subsea tieback to boost Troll gas exports
- Investment: just over NOK 4 billion.
- Expected contribution: around 11 billion standard cubic metres of gas.
- Ambition to start production as early as 2028.
- Development: two wells in a template and a pipeline tied into existing subsea facilities; umbilical and MEG line to be extended.
Project and partners
Equinor and partners Petoro, Shell, TotalEnergies and ConocoPhillips are investing just over NOK 4 billion in the TWIN subsea development, the third step of Troll phase 3 targeting gas from the Troll West reservoir.
Production and schedule
TWIN is expected to contribute around 11 billion standard cubic metres of gas. Equinor has an ambition to start production as early as 2028. The second step of Phase 3 will come on stream during 2026 and will support continued high production from Troll A and Kollsnes towards 2030.
Design and emissions
The project comprises two wells in a template and a pipeline connected to existing subsea facilities, with extension of the umbilical and MEG line. Both the platform and the onshore plant are powered by electricity from shore, meaning the gas will be produced with very low emissions.
Strategic context
Equinor says simplification, increased standardisation and reuse of existing infrastructure and equipment are being used to reduce costs and accelerate delivery. The company aims to halve costs and execution time for subsea projects and to develop six to eight such projects per year towards 2035, supporting jobs, value creation and continued gas exports; Equinor targets 1.3 million barrels per day production from the Norwegian continental shelf in 2035.
