DNV’s new training center will run full-scale experiments for a joint industry project aimed at investigating cost-efficient explosion load descriptions for process areas.

Why CFD should be part of your separator design? This goal of this goal is to allay any fears about CFD that you may have as a result of flashbacks to university class and a dizzying array of partial-differential equations.

Paradoxical effects can exist when expanding the capacity of natural-gas-transportation networks. This paper derives conditions where it can be expected, how the effect can be masked, and provide analysis to support identification in larger-scale networks.

In gas applications with high-pressure drops and/or high-velocity gas flow, acoustic-induced vibration (AIV) occurs when very high sound levels are propagated in piping. This can induce fatigue cracking of the pipe and potentially catastrophic pipe failure.

This month's papers cover a new method to evaluate the design pressure of flowlines and risers, pipeline integrity assessment, treatment and removal of sand from pipelines, and considerations around the in-situ burning of oil on water.

Setting optimal surface separation pressures are crucial for maximizing the surface liquid production from the wellstream feed. Where separator tests are not available, empirical calculations are often used, but with limitations. A method suitable across many conditions is proposed.

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).

The burning of oil in place (in situ) on water is a viable means of mitigating the impact of marine oil spills. This paper examines decision criteria and safe practices for deploying this method in both icy and warm conditions.

This paper discusses the available methodologies for remediation of a pipeline affected by sand and presents examples where the discussed methodologies have been applied.

The papers in this month's issue describe an optimization method for long-distance gas-transmission pipelines, a potential solution to handle produced water from subsea wells. the driving forces in paraffin deposition, and a novel method to verify leaks in a sulfur-recovery unit condenser.
