New rules requiring Mozambique’s LNG industry to supply 25% of production to the domestic market could stabilize gas deliveries to South Africa’s Secunda industrial center as the Pande and Temane gas fields near depletion.
The Absheron gas field expansion will supply additional natural gas to Azerbaijan’s domestic market and support its export commitments to Turkey, allowing Baku to stay focused on meeting its gas export obligations to Europe.
This work introduces a novel predictive methodology combining historical metocean data with real-time riser analysis for shallow water dynamically positioned rig operations.

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.

This paper describes the qualification process for a thermoplastic composite pipe manufactured for use in high-performance riser, jumper-spool, and intervention-line applications.

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.

Subsea processing is an evolving technology in ultradeepwater development and has the potential to unlock a significant amount of hydrocarbon resources. In this paper, the authors have reviewed the application of subsea systems in 12 deepwater fields and discussed the significance of each.

At the 2016 Gulf of Mexico Deepwater Technical Symposium in New Orleans, a presentation discussed the application of sensors and analytics in pipeline integrity management systems.
-
The Dakota Access Pipeline, which will connect the Bakken and Three Forks production areas, has received the regulatory go-ahead from the US Army Corps of Engineers.
-
This paper evaluates the feasibility of a number of production- and export-riser configurations for ultradeepwater applications.
