Offshore/subsea systems
The $5.1 billion ultradeepwater project is Angola’s first integrated cross-block development and sits at the top of Azule’s Southern African portfolio.
Equinor and its partners’ investment in the Troll West Increased Gas Recovery North (TWIN) project aims to unlock around 11 Bcm of additional natural gas from the Troll field, with first production targeted as early as 2028.
In the fourth development phase, a planned tieback would connect resources from two North Sea discoveries to existing infrastructure at the Johan Sverdrup field, pending project sanction.

An increasingly buzzy term tossed around at industry events, “digital twin” is leveraging data analytics, machine learning, and artificial intelligence to improve efficiencies from design to decommissioning. -
When two engineers lost their jobs during the industry downturn, they used the misfortune as an opportunity to develop an innovative concept that aims to make it a lot easier to move subsea gas long distances.

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.
