The Troll field, located 80 kilometres northwest of Bergen in the North Sea, stands as Norway’s largest gas producer, supplying 10 percent of Europe’s total gas needs. Troll Phase 3 focuses on extracting the gas cap that lies above the oil column in Troll West while maintaining oil production. The gas produced is sent to Troll A, then integrated into the existing infrastructure for further processing and distribution.
This development involves a comprehensive scope, including engineering, procurement, construction, installation, and commissioning for topside modification. The primary goal is to prepare the Troll A platform to handle and process gas from eight newly drilled wells at Troll West.

The initial stage of Troll Phase 3 was completed in 2021, during which a new module was installed on the Troll A platform to process gas from Troll West. Aker Solutions was responsible for the topside modifications and provided subsea systems for this first phase of development.
“We are excited to continue following the significant development of the giant Troll field and to move forward with the next step of Troll Phase 3. In-depth knowledge of Troll A, the equipment on the asset, and the modifications made in the first phase is essential, providing a strong foundation for executing this new scope,” said Paal Eikeseth, executive vice president and head of Aker Solutions’ Life Cycle segment.
Aker Solutions has been further entrusted with installing and preparing equipment for cleaning up the initial well fluids during the start-up phase of the new wells.
“We will have the lead responsibility for the interfaces between contractors in this project and will leverage our experience as integrators in complex energy projects, focusing on delivering high-value and optimised solutions. We are honoured to be a trusted contractor and look forward to continuing the close collaboration with Equinor on Troll,” Eikeseth added.
The engineering phase will involve multiple Aker Solutions offices. Project management, detailed engineering, procurement, and shop engineering will be handled by the Stavanger office, with support from teams in Bergen and Mumbai. Construction and prefabrication will be carried out at the company’s Egersund yard. OneSubsea, in which Aker Solutions holds a 20 percent stake, has previously been contracted to supply the subsea production system for this development.
The contract is set to commence immediately, with completion expected by the end of 2027. It will be registered as order intake for the Life Cycle segment in the third quarter of 2024.
