Offshore/subsea systems
This paper reviews the motivation and development of response-based forecasting from the perspective of the authors, reviewing examples and processes that have served as validation and led to modeling refinement.
This paper compares traditional welded techniques, such as above-water repair methods and underwater hyperbaric welding, with the novel options offered by subsea connectors purposely developed for corrosion-resistant-alloy-clad pipelines.
This paper introduces a technology for offshore pipeline inspection centered on an autonomous robotic system equipped with underwater computer vision and edge-computing capabilities.

We don’t include a structure like the Eiffel Tower with separators, pumps, and compressors on the top observation platform in an onshore development plan. And yet, how many jacket platforms are there around the world? -
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.
-
Operator or manufacturer’s reports and published papers are reviewed and a criterion is developed for subsea pump selection.
-
Production from an offshore Angola field has been decreasing because of subsea pressure declines amid water-cut increases and limited gas compressor capacity. The development process leading to the selection of high-boosting multiphase pumps is described.
-
Currently, the state of the art for subsea well control is based on hydraulic technology. Hydraulic fluid is supplied from a host facility to the subsea wells through dedicated tubes within an umbilical and is distributed to the wells.

Hurricane Energy is still on pace for first oil in 2019 for the Lancaster field, which may lead to more significant development in the UK North Sea.

The steel pipe manufacturer agrees to deliver outer pipes for pipe-in-pipe flowlines for a pair of recently-announced Aker BP projects in the Norwegian Sea.

Completion of the umbilicals system marks another step toward startup for the Total-operated ultradeepwater development offshore Angola.
-
Offshore project execution enhancement ideas are highlighted for debottlenecking, gas-hydrate-induced pipeline vibration, and the design of subsea systems for efficient startup.
-
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.
