Pipelines/flowlines/risers
The Japanese company ratcheted up the competitive nature of contracting for a floating production, storage, and offloading vessel and an onshore liquefied natural gas plant for the Abadi project by announcing dual front-end engineering design (FEED) contracts.
Work by researchers at the University of Saskatchewan aims to advance the understanding of clathrate hydrates, crystal cages of ice that can trap gas and liquids.
Electricity produced onshore powers oil production at Johan Sverdrup holding CO₂ emissions at only 5% of the global average.

Riser margins were abandoned when fluid columns in risers became too long with increasing water depth accessed when floating drilling units with subsea blowout preventers (BOPs) moved to deep water. -
A methodology is proposed for design of subsea flowlines and risers coupled with a subsea high-integrity pressure protection system (HIPPS) for fields with high shut-in tubing pressure (SITP).

This paper discusses the available methodologies for remediation of a pipeline affected by sand and presents examples where the discussed methodologies have been applied.
-
This paper presents a methodology to estimate the probability of failure of every individual corrosion defect and the residual likelihood of failure of an overall corroded pipeline segment after selected repairs, using structural probabilistic analysis.
-
This paper presents the results of tests conducted to design a fast-breaking gelled fluid for a debris-removal operation in a long, large-diameter subsea pipeline in the Asia Pacific region. where traditional pigging was not an option.
-
This paper highlights the issues and challenges surrounding pipeline trenching and burial in ice-gouge environments. The current state of practice is discussed along with the technology gaps that need to be addressed.
-
The present work describes the development of a 1D steady-state isothermal reservoir/surface gas-pipeline-network model. The developed model is an extension of the general pipeline-network model in which the deliverability from the wells is calculated.
-
Systematic experimental and modeling approaches to designing a safe operating strategy for a 5-km deepwater-subsea-flowline case study are presented to address unplanned shutdown and restart events for waxy-crude production.
-
Operators are increasingly recognizing the need for a systematic assessment and management of flexible pipe integrity, but the identification of critical criteria and the means to best achieve valid and efficient inspection and monitoring (I&M) continues to evolve.
