Offshore/subsea systems
The company has installed an autonomous drone system on Aker BP’s Edvard Grieg platform in the North Sea, enabling frequent, remote inspections from shore.
This paper describes the use of coiled tubing in a pilot project for carbon dioxide injection, enabling evaluation of the conversion of an existing oil field for CCS purposes and derisking storage-development uncertainties before having to cease hydrocarbon production.
This paper describes the first riserless coiled tubing services operation performed in a live subsea well and the associated improvements in efficiency, cost savings, and safety.

Subsea 7 completed the acquisition of Siem Offshore Contractors along with a cable-lay vessel and a support vessel. -
Aquabotix’s SwarmDiver technology marks a major milestone in the growing trend toward swarm-deployed underwater vehicles.

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.
