FPSO Cuulong MV9 External Turret
Scope of Work
SOFEC designed and constructed an external turret mooring system to moor the 149,500 dwt MODEC purpose-built FPSO. The FPSO receives produced oil and reinjects both produced gas and water. The SOFEC turret is designed to support a single production platform in Phase I, with space to accept additional production from a second future production platform in Phase II of the project.
