Pipelines/flowlines/risers
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 contract will cover the design and manufacturing of tree systems, flexible flowlines, a manifold, and controls, as well as installation of the subsea production system.

As compressor stations are added to the natural gas gathering and transmission networks, the potential noise issues are coming under increasing public scrutiny at the same time as regulations are being rolled back. -
This paper considers some of the challenges and learnings associated with the application of chemicals for preservation of coated pipe/flowline for a major liquefied-natural-gas (LNG) project in Australia.

The understanding of solid-particle flow regimes in pipelines for any operational conditions is important for identifying the nature of particle interaction and movement. In this paper, a comprehensive analysis of solid-particle flow regimes in stratified flow in a horizontal pipeline is presented.

The downturn and lack of investment for new projects are likely to impact the onshore pipeline industry toward the end of the decade. But the long-term drivers for pipeline construction, notably the increased demand for gas in regions such as Asia, remain stable.

A study using a dynamic multiphase-flow software simulated a rapid-unloading event and determined the gas fraction in the riser annulus and the effect on riser fluid levels.

Natural-gas-infrastructure reliability is critical for the energy sector. When capitalizing on old pipelines to transport natural gas, operators run the risk of partial blockage. In this study, the authors develop a multirate test method to detect partial blockage in a gas pipeline.

This paper describes a new direct electrical heating method in flexible-pipe systems. The method effectively expands the operational envelope of flexible unbonded pipes with greater control of hydrate plugs and wax precipitation by distributed heating along the entire pipe length,

Thermoplastic composite pipe (TCP) is a spoolable, fully bonded pipe with glass or carbon-fiber reinforcements. While most often used in deep water, the combination of a solid wall, spoolability, and corrosion resistance makes TCP attractive for production-flowlines in shallow water also.
