production rates at P-52 required an 18-in. oil export pipeline. Instrumented pigging requirements dictate the export riser have the same diameter. This large-bore specification, combined with the deepwater site, put this application outside
Analyses assessing the possible use of a free-standing hybrid riser (FSHR) as part of an offshore field development export system should both thoroughly address fatigue damage during installation and determine the allowable sea states for deployment.
The export pipeline system includes two modules permitting future connections and another serving as a contingency for the freestanding hybrid riser (FSHR), making the infrastructure flexible enough to be used in its full capacity after the original field is depleted.
