Abstract: A connection device for joining two pipe sections in a body of water has a first tubular body having a spherical face; a second tubular body having at least one spherical face; a tubular pusher arranged about the second tubular body and having a spherical face; a first mechanism for coupling the second tubular body between the first tubular body and the tubular pusher and providing a spherical coupling between the first and the second tubular body; and a second mechanism for blocking any movement about the spherical coupling of the second tubular body with respect to the first tubular body and the tubular pusher.

Abstract: A connector for a pipeline, in particular for conveying hydrocarbons, extends along a longitudinal axis and has a gripping portion configured to be fitted around and clamped to the outer face; a sleeve portion, which is mounted in sliding manner to the gripping portion; a metal front gasket configured to be placed between the front end face and a face of the sleeve portion; and linear actuators connected with the gripping portion and the sleeve portion to axially compress the metal front gasket between the front end face of the pipeline and the face of the sleeve portion.

Abstract: A system for connecting two conduits in a body of water, exhibits a first tubular structure, which is coupled to a conduit that extends along a first longitudinal axis; a second tubular structure, which is coupled to another conduit that extends along a second longitudinal axis and comprises a tubular member, and a sleeve, which is telescopically coupled to the tubular member, and faces the first tubular structure; and an actuating assembly, which comprises a bidirectional translating device configured to selectively displace the sleeve forward and backward to selectively couple and uncouple an end portion of the sleeve and the first tubular structure.

Abstract: A vessel for laying a pipeline includes a plurality of workstations disposed along a pipelaying path that includes an upstream portion away from a first end of the vessel and a plurality of ramps, includes a first ramp and a downstream second ramp disposed along the pipelaying path, in the region of the first end of the vessel. Each of the plurality of ramps has a first upstream end, a second downstream end, and an adjustable inclination. The downstream end of the first ramp is positioned inboard of the first end of the vessel and above the bottom of the vessel and the upstream end of the second ramp is positioned inboard of the first end of the vessel and above the bottom of the vessel. An external ramp assembly includes ramps that can be pivoted relative to one another and locked in a selected position.
