New Concept of Export Line For Deepwater Fields

A novel concept of export line is planed to be implemented on the Girassol field, in 1350 m WD Offshore Angola, to link the FPSO and an offloading buoy, over a distance of one nautical mile. The design includes two subsurface lines forming a piggable loop. Each 16 OD steel line has a W shape with buoyancy modules over the central arch. The concept is applicable in any water depth greater than about 500 m, for oil fields in mild environment and is candidate for use whenever offloading is carried-out through a remote buoy at a great distance from the storage unit.
