More Information
Summary:An offshore hydrocarbon production system includes a vessel (12) with a turret (16), and a fluid swivel (50) on the turret that is connected to risers (41-43) that extend to the sea floor (26), wherein a drilling/workover rig (60) on the vessel can lower tubing (65) 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 (54) that extend from the rotatable part of the fluid swivel to fittings (55) on the hull (14), are supported on a gantry (80) that is fixed to the hull and having a gantry middle portion (106) that extends over the turret. The gantry middle portion extends higher than the top (88) of the rig. Un sistema de extraccion de hidrocarburos en alta mar incluye una embarcacion (12) con una torre (16) y una cabeza de sonda de fluido (50) sobre la torre que es conectada con los tubos de subida (41, 43) que se extienden hasta el fondo el mar (26), en donde una sondeadora de perforacion/reacondicionamiento (60) sobre la embarcacion puede bajar la tuberia (65) hacia el fondo del mar sin peligro que la tuberia se enrolle alrededor de los tubos de subida cuando el casco se alinea a la direccion del viento. La sondeadora es montada sobre la torre. Los tubos (54), que se extienden a partir de la parte susceptible de ser girada de la cabeza de sonda de fluido hacia los accesorios (55) sobre el casco (14), son soportadas sobre una grua de portico (80) que es fijada en el casco y que tiene una porcion media de grua (106) que se extiende sobre la torre. La porcion media de grua se extiende mas arriba que la parte superior (88) de la sondeadora. La figura mas representativa de la invencion es la numero 1.
