Offshore/subsea systems
The awards build on Tenaris’ role in earlier phases of the ultradeepwater Black Sea project.
An earlier deal to double Israel’s gas exports to Egypt led to approval of Leviathan’s Phase 1B expansion by guaranteeing long-term cash flow to finance the project.
Marking a major milestone as the Gulf of Mexico’s second 20,000-psi deepwater development, the project underscores how advanced high-pressure technology, management of flow challenges, and the floating production system’s role as a regional hub are helping open the door to more Inboard Wilcox development.

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. -
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.
-
Operators are increasingly using existing offshore infrastructure for asset life extension, and developing new marginal stranded fields rather than develop new large greenfields. Subsea processing is an enabling technology in this goal.
-
Southwest Research Institute is adding a new facility to its capabilities in testing and evaluating subsea equipment and systems.
