Offshore/subsea systems
The Begonia and CLOV Phase 3 subsea tiebacks are each sending production to nearby FPSOs.
Shell became the first international company to operate producing fields offshore Brazil and the first to navigate the country’s complex and detailed decommissioning permitting process, which involved extensive environmental assessments, regulatory approvals, and coordinated stakeholder engagement.
North Sea tieback to the Troll C platform could begin production by the end of 2029.

The need to economically invest in offshore exploration and production has inspired a wide range of innovations in Norway to drastically reduce costs, which can lead to changes in offshore operations around the world. -
The BC-10 asset, located in deep water offshore Brazil, produces heavy oil in the range of 16 to 24 °API. In this article, two examples of production optimization for this field will be provided (further examples are available in the complete paper).

This paper describes the CLOV deepwater megaproject in Block 17 offshore Angola, which cost USD 8.4 billion to first oil.
-
Moving to higher-capacity wellhead systems for high-pressure and high-temperature (HP/HT) environments will require a larger mandrel and conductor-casing size.
-
To help lower costs of offshore projects, DNV GL has launched initiatives focused on the use of composite components.
-
A RPSEA project identified the gaps in technology that are the most pressing for multiphase-flow measurement.
-
Deepwater production has become more reliant on the integrity of subsea, umbilical, riser, and flowline (SURF) systems. A JIP explored cost-effective inspection and maintenance options.
-
Douglas-Westwood (DW) expects the expenditure of subsea vessel operations to begin a gentle upswing after next year.
-
As subsea electric lines age, they are prone to cracks that allow seawater in, reducing their effectiveness, and if the leaks are bad enough, they can shut down operations.
-
Statoil is going to work to put its enormous Johan Sverdrup discovery into production, showing that even one of the most explored parts of the North Sea still has significant potential.
