As HPHT wells push equipment to the edge of material limits, operators are turning to advanced thermoplastics and sealed electrical assemblies to maintain system integrity. From ESP insulation to BOP control systems, the right component design can prevent failures, lower intervention costs, and extend equipment life in the harshest offshore environments.
The new development is estimated to hold 46 million bbl of recoverable oil and is planned to start up in late 2028.

In a $60 to $70 oil environment, the subsea market is poised to grow around 7% annually up to 2025. But a significant portion of this activity is at risk if the price of Brent crude falls to $50 per barrel. -
The subsea operations company said its most recent campaign is the first fully unmanned offshore pipeline inspection completed “over the horizon,” surveying up to 100 km from the shore.
