Offshore loading or production system for dynamically positioned ships

摘要

An offshore loading or production system for dynamically positioned ships, comprising a riser means (4) extending between a supply means and a coupling head (5) for connection to a connecting means (6) on the ship (1). The riser means (4) comprises a lower riser portion (7) extending along the seabed (8) and being arranged to take up a wavy shape above the seabed by means of at least one bottom-anchored first buoyancy element (9), and an upper riser portion (10) of which the lower end is connected to the lower riser portion (7) via a second buoyancy element (11), and of which the upper end is connected to the coupling head (5) via a swivel unit (12). The second buoyancy element (11) is connected to a supporting anchoring (17) extending along the seabed (8) in a direction away from the lower riser portion (7).
