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 objective of this study is to investigate comprehensively the effects of the expansion process on the pipe mechanical properties and collapse performance and to develop a reliable risk-based collapse-strength design for the expandables. -
When two engineers lost their jobs during the industry downturn, they used the misfortune as an opportunity to develop an innovative concept that aims to make it a lot easier to move subsea gas long distances.
-
Risk-based design is very important, especially for complex systems, because a deterministic approach may not provide a strong underpinning to the reliability estimation of the downhole tools. We have to reduce the probability of failure.

In 2016 , several coordinated actions led to trespass and vandalism of pipelines and pipeline facilities, some of which were prosecuted as felony criminal acts. The defendants in several of these cases have raised a "necessity defense" to their actions, and two courts have now allowed that defense.

Subsea 7 completed the acquisition of Siem Offshore Contractors along with a cable-lay vessel and a support vessel.
-
At least four US pipeline companies have seen their electronic systems for communicating with customers shut down over the last few days, with three confirming it resulted from a cyberattack.
-
The steel pipe manufacturer agrees to deliver outer pipes for pipe-in-pipe flowlines for a pair of recently-announced Aker BP projects in the Norwegian Sea.
-
Offshore project execution enhancement ideas are highlighted for debottlenecking, gas-hydrate-induced pipeline vibration, and the design of subsea systems for efficient startup.
-
A computational fluid dynamics model is proposed to analyze the effect of hydrate flow in pipelines using multiphase-flow-modeling techniques. The results will identify the cause of pipeline failure, regions of maximum stress in the pipeline, and plastic deformation of the pipeline.
-
Southwest Research Institute has developed a leak detection system to autonomously monitor pipelines for hazardous chemical spills. R&D Magazine recently recognized the system as one of the 100 most significant innovations of 2017.
