The awards build on Tenaris’ role in earlier phases of the ultradeepwater Black Sea project.
Engineering, procurement, construction, and installation awards made at the end of 2025 are expanding Saipem’s role in Turkey’s two largest offshore gas fields, plus Saudi Arabia’s Berri, Abu Safah, and Marjan oil fields and Qatar’s North Field gas giant in the Persian Gulf.
The Gorgon Phase 3 project aims to counter declining reservoir pressure to sustain gas supplies to Western Australia’s domestic market and support LNG exports to Asia.

The Norwegian provider of pipeline safety and technical verification services announced its withdrawal after actions taken by US lawmakers this month. -
A combination of computational-fluid-dynamics and finite-element modeling offers a potentially powerful tool for assessing and diagnosing multiphase-flow-induced vibration problems in hydrocarbon-production piping systems.
