SLB, Subsea7, and Aker Solutions’ JV finds work on $1 billion North Sea gas project

OneSubsea, a joint venture (JV) backed by SLB, Aker Solutions, and Subsea7, has tucked a new assignment under its belt for a project that aims to bolster gas infrastructure at a giant oil and natural gas field in the northern part of the North Sea, which Equinor, a Norwegian state-owned energy giant, operates.

The contract award, which OneSubsea deems as “sizeable” comes on the heels of Equinor’s announcement about the planned investment of over NOK 12 billion (close to $1.13 billion) into increasing the gas infrastructure in the Troll West area through the second stage of the Troll Phase 3 (TP3 II) project to accelerate production from the reservoir and maintain the high gas export levels from the Troll and Kollsnes value chain leading up to 2030.

The subsea technology and solutions provider highlights that the latest deal leverages an existing long-term contract for the execution of the second stage of Phase 3 for the Norwegian energy heavyweight’s Troll project in the North Sea off the coast of Norway.

The new assignment will see OneSubsea take advantage of configurable solutions compliant with NCS2017+ for standardized subsea production systems for application on the Norwegian Continental Shelf (NCS) to accelerate field delivery of the subsea tie-back to existing infrastructure at the Troll A platform. The project aims to up the production ante from the reservoir equivalent to about 55 billion standard cubic meters of gas.

Mads Hjelmeland, CEO of SLB OneSubsea, commented: “We deeply appreciate our long-standing relationship with Equinor, and we look forward to continuing our collaboration on the Troll field. This frame agreement is and has been an important conduit for joint value creation, supporting the transparency, teamwork and collaborative solutions necessary to unlock maximum value from our NCS projects together.”

With the annual contribution from the new development expected to amount to around 7 billion standard cubic meters of gas at its peak, this project is anticipated to require modification work on Troll A. According to OneSubsea, the eight-well project is the latest to be signed under the collaborative frame agreement signed with Equinor in 2017.

The firm’s expanded scope entails nine standard NCS2017+ vertical trees, including wellheads, tubing hangers, subsea control modules, compact bridge modules with wet gas flow meters, two four-slot templates, topside controls integration, and two umbilicals. The first wells are anticipated to come online at the end of 2026.

OneSubsea has won several new assignments lately, including a deal with the Turkish Petroleum Offshore Technology Center (TP-OTC) for a natural gas project in the Black Sea in Türkiye and another agreement with Equinor for the Wisting field offshore Norway and the Bay du Nord project located off the coast of Newfoundland and Labrador, Canada.
