This follows the completion of the first stage in 2021, where Aker Solutions delivered a new module for the platform and subsea systems for Stage I of the field development.

Aker Solutions’ Life Cycle segment executive vice-president and head Paal Eikeseth said: “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.”

Additionally, Aker Solutions is tasked with the installation and preparation of equipment necessary for the clean-up of initial well fluids during the wells’ start-up phase.

The contract work will be distributed across several Aker Solutions offices, with project management, detail engineering, procurement and shop engineering being conducted from the Stavanger office in Norway, supported by teams in Bergen, Norway and Mumbai, India.

Construction and prefabrication will take place at the company’s yard in Egersund.

OneSubsea, which is 20% owned by Aker Solutions, has also been contracted previously to provide the subsea production system for the project.

The contract commences immediately and is due for completion by the end of 2027.

Earlier this month, Equinor announced the partial electrification of the Troll B and C platforms in the North Sea from shore.
