Background and Objectives Subsea separation successfully implemented on the Troll and Tordis fields (Statoil), Pazflor (Total), Marlim (Petrobras), and Perdido and BC-10 (Shell).
Conducted by Joint Industry Project with Statoil as operator and Chevron, Petrobras, Total, and FMC Technologies as participants

Key Conclusions
The CompactSep system combines the GLCC’s liquid capacity with the DeLiquidiser’s gas capacity. The work developed and qualified an inline separator system with full turndown and slug handling capability at a wide range of realistic conditions.
At design fluid conditions (crude oil, 50 bar): Gas qualities requirement was GVF > 0.995, with measured
result of GVF between 0.995 and 0.999. Liquid quality requirement was GVF < 0.1, with measured
results of GVF between 0.02 and 0.1 The liquid separation efficiency was typically 99 to 99.9%.
