FLNG Coral South Permanent Internal Turret

 
 

Scope of Work

SOFEC will design, construct, fabricate and install a permanent internal turret for the Eni Coral South FLNG.

The Coral South FLNG Turret represents SOFEC’s 4th Single Point Mooring System for LNG related business and using SOFEC’s High Integrity Pressure Protection Systems (HIPPS) technology. SOFEC’s design enables a reduced pressure envelope through the swivel stack by efficiently locating the HIPPS on the geostationary part of the turret. This results in increased operational safety on the FLNG vessel, thereby increasing safety for personnel. This technology also clears deck space on the vessel where real estate is at a premium.
