About the Workshop
In mid-September 2015, the first subsea compression system was started up, representing the culmination of almost three decades of research, testing and rigorous technology qualification. The Åsgard subsea compression projects started in 2005, and the Gullfaks subsea compression project a few years later. Both systems are now in operation so subsequently the subsea processing cluster has delivered a successful launch of the “third” largest subsea processing technology following subsea pumps and subsea separation (liquid/liquid and gas/liquid).
It is also important to remind ourselves that there are > 100 subsea pumps that have been delivered to customers over the past 20 years. Recently vendors have brought their new pumps and technologies to the market and are expecting to see a growth in future opportunities.
Historically there have been some subsea separation projects globally, but the industry has not been able to sanction many new projects over the last few years. Key projects for water/oil separation (Marlim, Tordis and Troll Pilot) and gas/liquid separation (Pazflor, Åsgard) have demonstrated the performance and value of the technology, but still new projects are difficult to get sanctioned. What is the reason for the operators not being able to justify the investment in subsea separation technology to increase recovery from their fields?
The learnings from the first subsea compression projects may be brought forward to even more challenging projects with longer tie-back distances.
