Processing systems/design
This article addresses the challenges of managing water-soluble organics (WSOs) in offshore produced water. It provides a brief discussion of the chemistry, along with strategies and technologies that can be used to manage WSO levels in produced water, thus facilitating compliance with regulatory overboard water-quality guidelines.
The new technology, recently highlighted at OTC, has received a statement of maturity from ABS.
War‑related infrastructure damage is beginning to influence global energy supply chains in ways that could reshape project development and capacity growth.

Offshore project execution enhancement ideas are highlighted for debottlenecking, gas-hydrate-induced pipeline vibration, and the design of subsea systems for efficient startup. -
An operator in the western Gulf of Thailand retrofit two partial-processing water-management systems on mobile-offshore-production-unit platforms for bulk removal and treatment of produced water. Water debottlenecking increased oil production by 80% and reduced the infield transfer volume by 62%. Th

A JIP turned the dial closer to achieving all-electric subsea processing with the underwater testing of a subsea variable speed drive in a harsh water environment.

The paper discusses dehydration performance of two units in two plants—with preinhibited glycol/antifoam/pH adjuster blend vs. neat glycol with periodic injection of antifoam and pH-adjuster inhibitors. The insights present an opportunity for significant operating and capital costs reduction.

This article highlights some of the code and registration issues the Savvy Separator engineer encounters when retrofitting a vessel with internals to improve or restore the process performance of the separator.
-
Widening the use of subsea separation and produced-water reinjection or discharge systems to unlock oil resources depends on improving subsea water-quality measurement.

Part 2 of this two-part series presents a new methodology for sizing and rating three-phase separators based on quantifying the actual mechanisms and physics that govern separation performance. An example illustrates the calculations needed to achieve the specified outlet fluid qualities.
-
Why is designing with human error in mind so critical? Consider that nearly 80% of all offshore facility accidents are caused by human errors, and 64% of these accidents happen during operations.
-
By understanding the factors involved in oil droplet coalescence, the Savvy Separator engineer can assess the operational/chemical factors in the treatment system that are affecting droplet growth and make adjustments to enhance coalescence rates.

In this work, the authors demonstrate at a laboratory scale the possibility of using a radio-frequency heating system as a heat exchanger.
