Boring and exploitation system for oil reservoir in sea, has connectors situated above application point and comprising pre-stress exertion units to exert axial pre-stress on ring, and other connectors situated below application point

摘要

The system has connectors (8) situated above a tension application point and comprising axial pre-stress exertion units to exert an axial pre-stress on a ring. Connectors (7) are situated below the point, and deprived of the units to exert the axial pre-stress on the ring. The ring is rotatably mounted on a male element, and has studs that cooperate with studs of a female tubular element to form a bayonet assembly.
