SUBMARINE CONNECTION ASSEMBLY

摘要

A submarine connection for interconnecting a riser pipe and a flexible pipe (26). The riser pipe has an upper end and the flexible pipe (26) has a lower end (30). A connection assembly includes a rigid fitting having a first limb (64) to be connected to the lower end (30) and a second limb (66) with a connector (67) on the end, and a body (36) having a head (42) and an opposing base (46) provided with an end piece (52) to be mounted on the upper end. The connection assembly also includes first guiding elements (60, 86) secured to the body (36), extending in a position at a distance from the axis of the end piece (52), and second guiding elements (76, 81) secured to the first limb (64), suitable for cooperating with the first guiding elements (60, 86).

主权项

1. An underwater connection assembly for connecting, between a seabed and a sea surface, a riser extending from the seabed with a flexible pipe leading to the surface, the connection assembly comprising:
the riser having an upper end, the flexible pipe having a lower end; a rigid U shaped coupling having a first limb connectable to the lower end and an opposite second limb ending in a connector; a frame having a top configured to be connected to a float and an opposite bottom; an end piece on the bottom and having an axis oriented toward the top end for being mounted on the upper end; a guide device configured to allow the connector to be guided in movement toward the end piece so that the connector and the end piece can be coupled together; the guide device comprises first guide members secured to the frame, and second guide members secured to the U shaped coupling and the second guide members are able to collaborate with the first guide members, and the first and second guide members further comprise a damper configured to damp the movement of the connector toward the end piece.
