Severe slugging is characterized by large pressure fluctuations at the base of the riser and is accompanied by fluctuations in fluid delivery from the top of the riser. This instability has negative effects on downstream equipment.

Continued suppression of global oil prices has questioned the viability of several large and ultradeepwater projects. Article covers Douglas-Westwood’s deepwater expenditure forecast for the 2016–2020 period, and the effect of reduced rig demand on deepwater Capex growth.

Used extensively by the food, chemical, and pharmaceutical industries, the mechanical-vapor-recompression (MVR) process is viewed as a reliable method for recovering demineralized water from concentrated brines. This paper reports on performance of an advanced MVR system in north-central Texas.

This paper analyzes the various selection methods of integrated template structures (ITSs) for use in the Arctic environment. Operation and installation of subsea modules in the Barents Sea are also analyzed in this paper.

Decision making is a critically important part of engineering. In this article, the author argues that the day-to-day project execution decisions are more important than major project decisions and deserve more attention.

This paper presents a statistical analysis approach to weather windows of opportunity, which are defined as the time span over which the stringent, multiparametric conditions required by weather-sensitive marine operations (such as heavy lift, topside float over, and pipeline tie in) are met.

The assessment of service life extension is not unique to oil and gas facilities, and commonalities exist in evaluating the equipment and components in other sectors.

A quantitative, probabilistic risk modeling tool used for more than a decade by the NASA might help the offshore industry prevent low-probability but high-impact incidents.

The oil price downturn has created a precarious job market for aspiring engineers, especially in disciplines like flow assurance that are closely linked to high-cost deepwater development. However, despite the economic climate, it is still possible for people entering the job market to succeed.

This paper discusses novel technologies for increasing the energy efficiency of offshore oil and gas platforms. Three case studies are in progress that are based on actual oil-producing platforms—two on the Norwegian Continental Shelf (NCS) and one in the Brazilian basin.
