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.

Shell reported it has not observed any signs of oil on the water associated with a fire on the Enchilada platform, located in the US Gulf of Mexico. -
Fluid Efficiency and Rhapsody Venture will partner to refine and launch a new molecular technology to improve the flow in pipelines.
-
Sensor systems for pipeline inspections from Ingu and Rheidiant are among the initial selections to receive funding under Chevron’s CTV Catalyst Program.
-
To reduce the risks to arctic pipelines from natural or geologic hazards, a more sophisticated approach to routing compared to traditional methods based on only the shortest length of pipe or connectivity to existing infrastructure is needed.
-
As the design methodologies evolve for arctic pipelines, strudel scour, permafrost thaw settlement, and ice gouging need to be factored in with environmental and geotechnical data, limit states, and trenching and backfilling activities.
-
The future of many offshore developments hangs on extending the lives of mooring lines and risers.
-
We have seen in recent years many technological advancements in tubular-manufacturing technology. Tubulars also have become part of the data-transmission network and slowly will converge with the data-handling and data-transmission systems.
-
Brazing technology allows metallurgical joining of dissimilar materials by use of a filler material.
-
This work is a study of collapse pressure of perforated pipes to evaluate the effect of lateral perforations on the radial resistance of pipes under external pressure.

Sea lines transporting gas in the Persian Gulf exhibit different thermal regimes in different regions. This study summarizes hydrate-inhibition practices for these sea lines, and indicates a possibility of using them as indirect thermometers to provide important physical oceanographic data.
