ABSTRACT:
A turret that is rotatably mounted on a vessel and connected to risers extending down to sea floor wells, is constructed so the turret is of moderate diameter to enable the use of a moderate size bearing and moderate weight turret, while providing room around the terminations of the upper ends of the risers. The risers (46A, 46G, FIG. 3 ) extend through tubes (62, 70, 72) which are oriented at an angle to the turret axis (22), so the lower ends of the tubes lie on large diameter circles to be considerably spaced apart, while the upper ends of the tubes are closer together to fit within the inside of the moderate sized bearing (60). The upper ends of the risers may be terminated at a plurality of different levels (90, 92, 94) within the turret to provide room around each termination.
