Abstract
An offshore hydrocarbon production system includes a vessel () with a turret (), and a fluid swivel () on the turret that is connected to risers () that extend to the sea floor (), wherein a drilling/workover rig () on the vessel can lower tubing () toward the sea floor without danger that the tubing will wrap about the risers when the hull weathervanes. The rig is mounted on the turret. Pipes () that extend from the rotatable part of the fluid swivel to fittings () on the hull (), are supported on a gantry () that is fixed to the hull and having a gantry middle portion () that extends over the turret. The gantry middle portion extends higher than the top () of the rig.
