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.

Obstacles remain to keeping offshore development competitive with its onshore counterpart. Can the industry advance technology at a pace where the subsea segment will see a resurgence? -
Since the Macondo disaster, industry publications have discussed the equipment, connections, and interfaces needed for capping and containing a blowing subsea well, but they give little insight into developing a well-specific subsea capping contingency plan.

McDermott announced a letter of award for a contract from Reliance Industries for the deepwater KG-D6 subsea field development in the Krishna Godavari Basin.
-
Baku Shipyard completed the sea trials of BP's subsea construction vessel Khankendi, which is being constructed for the Shah Deniz Stage 2 project.
-
WiSub will lead a consortium with Statoil, Kongsberg, Saab, and other companies and universities to develop a standardized interface for AUV docking with subsea structures, as well as bi-directional power transfer to help charge sensor networks.
-
Emphasis on identifying more-efficient subsea boosting solutions has led to a number of initiatives in the industry.
-
This study examines how subsea processing (SSP) can develop into an important enabling technology for future ultradeepwater-field developments and long-distance tiebacks.
-
The costs of subsea boosting systems have been reduced by adopting three primary strategies: simplifying the system design to reduce weight and cost, simplifying the installation and intervention, and reducing complexity and risk.
-
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.
-
The expanded research and testing capabilities offer the only vertical test rig for subsea safety valves and one of the largest high-pressure natural gas test facilities in the world.
