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.

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. -
Completion of the umbilicals system marks another step toward startup for the Total-operated ultradeepwater development offshore Angola.
-
Offshore project execution enhancement ideas are highlighted for debottlenecking, gas-hydrate-induced pipeline vibration, and the design of subsea systems for efficient startup.
-
The workflow aims to reduce the startup time of a subsea production system (SPS). A dynamic integrated model is used to adjust the scheduled SPS startup time. The model evaluates the dynamic simulation response of a large field startup by integrating a reservoir- and gathering-network model.
-
The shutting in of unprofitable offshore wells and the requirements for their plugging and abandonment is attracting more attention to what is being done with the associated subsea equipment. The benefits of leaving subsea systems in place vs. recovering them are being considered.
-
A JIP turned the dial closer to achieving all-electric subsea processing with the underwater testing of a subsea variable speed drive in a harsh water environment.
-
Statoil has submitted a long-awaited development plan for what will become Norway’s northernmost development.
-
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?
-
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.
-
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.
