... of these prospects, using only field proven technologies. The integrated solution consists of two major components: a) an Autonomous Subsea Tieback Enabling Platform (ASTEP), which is a Normally Unattended Installation (NUI) semisubmersible platform that is moored adjacent to the subsea wells and provides power...

These barriers are slowly being eliminated and a small number subsea wells have now been implemented with in-well fiber...

... to maintaining healthy well barriers and active monitoring assures the barriers are in place. In subsea wells, the only annulus that can be monitored in real time is between the tubing and production casing (aka A-annulus). When an anomaly is detected in the A-annulus, then a diagnostics and intervention program...
