METHOD FOR INSTALLING A HYBRID COLUMN IN AN EXPANSE OF WATER, HYBRID COLUMN AND ASSOCIATED FLUID EXPLOITATION INSTALLATION

摘要

This method involves positioning a riser (22) in a vertical configuration and completely submerging a buoy that supports the riser (22). It involves inserting a male connection element (62) carried by the buoy into a female connection element (64) carried by the riser (22) and immobilizing the male connection element (62) in an accommodating passage (92) defined by the female connection element (64). The female connection element (64) comprises at least one surface (98) for guiding the male connection element (62) toward the accommodating passage (92). The step of inserting involves guiding the male connection element (62) toward the accommodating passage (92) through contact with a guide surface (98) of the female connection element (64) which has a vertical section diverging away from the accommodating passage (92) toward the male connection element (62).
