What is the primary purpose of subsea compression technology?

Subsea compression is designed to boost the pressure of gas directly on the seabed, facilitating its transport to processing facilities and significantly increasing the recovery rate from gas fields. This technology helps to extend the economic life of mature reservoirs by maintaining optimal flow rates and reducing backpressure.

Why is Equinor a key player in subsea compression technology?

Equinor has been a global frontrunner in deploying subsea compression, notably at its Åsgard field, which was the world's first subsea gas compression facility. Their continued investment underscores a strategic commitment to enhancing efficiency, maximizing recovery from existing assets, and reducing the environmental footprint of their offshore operations through technological innovation.

What expertise do the OneSubsea joint venture partners bring to this project?

OneSubsea combines the strengths of SLB (subsea production systems and services), Aker Solutions (subsea trees, manifolds, and processing systems), and Subsea7 (subsea construction and installation services). This integrated approach allows them to deliver comprehensive, end-to-end solutions for complex subsea projects, from engineering and manufacturing to installation and commissioning.
