High-Voltage Subsea Pump Enables Low-Cost Boosting
Subsea pumps are used for gas/liquid separation, subsea compression, and subsea boosting. Solutions aiming at cost reductions are crucial to make subsea processing projects feasible. A cost- and complexity-reduction solution for the subsea electrical power supply is a critical consideration.

Water debottlenecking increased oil production by 80% and reduced the infield transfer volume by 62%. Th
Designing Subsea Systems for Efficient Startup To Mitigate Topside Downtime
The workflow aims to reduce the startup time of a subsea production system (SPS). A dynamic integrated model is used to adjust the scheduled SPS startup time. The model evaluates the dynamic simulation response of a large field startup by integrating a reservoir- and gathering-network model.
Hydrate-Induced Vibration in an Offshore Pipeline
A computational fluid dynamics model is proposed to analyze the effect of hydrate flow in pipelines using multiphase-flow-modeling techniques. The results will identify the cause of pipeline failure, regions of maximum stress in the pipeline, and plastic deformation of the pipeline.

This paper aims to develop a Brazilian baseline for front-end planning and cost estimation of the decommissioning, removal, and disposal options.
Decommissioning To Become Big Business
Whether you are involved in the design and construction of new facilities or the decommissioning of existing facilities, having a solid understanding of decom makes a lot of sense. Are you ready as all around the world offshore facilities have reached, or are reaching, the end of their design life?
Arctic Pipeline Route Selection
To reduce the risks to arctic pipelines from natural or geologic hazards, a more sophisticated approach to routing compared to traditional methods based on only the shortest length of pipe or connectivity to existing infrastructure is needed.
Concept for Ice-Resistant Offshore Terminal for Arctic LNG Export
Cost and delivery of long-distance natural gas pipelines to a distant liquefaction facility at a warm-water port has become excessive, and environmental restraints have been increasing. An alternative is an offshore ice-resistant LNG port accommodating a new class of LNG transport vessels.
Design Tools for Arctic Subsea Pipelines
As the design methodologies evolve for arctic pipelines, strudel scour, permafrost thaw settlement, and ice gouging need to be factored in with environmental and geotechnical data, limit states, and trenching and backfilling activities.

Nanotechnology Advances in the Oil Field
As practitioners we don’t always convey that the oil and gas industry is at the forefront of many different technologies, but we should, if only because it can be a real selling point to attract young people to our industry. In that spirit, I selected three papers that deal with nanotechnology.
