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.

Vibration-induced fatigue failures of pipework smallbore connections result in elevated safety risks and costly interruptions to normal operations. A common cause is poor design. This article discusses design considerations to avoid these failures. -
A relatively small concentration of a defoamer can have a significant impact on the dynamics of multiphase flow within a pipe, but the effect is generally temporary.

There are few deepwater-pipeline operators with expertise in pipeline repairs. This paper describes a strategy developed and implemented on deepwater-pipeline intervention, based on a deepwater operational experience built over a decade.

This paper illustrates a numerical approach to estimate the deposition profile of precipitated wax crystals and its effect on flow-related parameters in pipelines. Options for avoiding these issues are also explored.
-
As with many monitoring and decision support tools, riser management systems originate from the engineering community so may assume a large degree of domain knowledge.
-
A program was devised to test the manufacturability of shrink-fit joints made from high-strength (greater than 100 ksi) mill pipe and forged couplings.

Gas production in the South China Sea has seen an increasing trend of pipelines operating in high-pressure, high-temperature (HP/HT) conditions. This has led operators to look beyond the conventional stress-based design and move into strain-based design using the lateral-buckling-design approach. This paper presents both construction challenges and operational works p…

As natural gas pipeline systems have grown larger and more complex, the importance of optimization of design and operation of pipelines has increased. This paper examines the optimization issue for the Egyptian gas transmission pipeline network.

Field trials were conducted by BP on the commercial version of wired pipe with a comprehensive suite of logging-while-drilling (LWD) tools, measurement-while-drilling (MWD) functionality, and rotary-steerable- capability on two Wyoming wells in 2007.

Solid-expandable tubular (SET) is widely used to patch casing and has proved to be cost effective.
