Coupled analysis of FPSO and CALM buoy offloading system in West Africa
FPSO and CALM (Catenary Anchor Leg Mooring) buoyoffloading systems are being extensively employed in water fieldof West Africa. In this paper we did some research on the responseof FPSO and CALM offloading systems under special environmentconditions inWest Africa. It is found that Swell dominate sea...
