摘要： A system for temporarily connecting an underwater station arranged on the bed of a body of water and a surface facility has an elongated conducting member with one end connected to the underwater station and one free end selectively and temporarily connectable to the surface facility; a marker buoy; and a cable connected to the free end of the elongated conducting member and to the marker buoy to quickly recover the free end of the elongated conductor element when it is necessary to connect the underwater station via the elongated conducting member to the surface facility.

摘要： A coupling system (12) between a riser (2) and an underwater supporting structure (10), includes a coupling seat (13) and a coupling head (14) which can be inserted in the seat. A pull connector (16) constrains the head (14) to the seat (13) to prevent the extraction of the head (14) but to allow rotation of the head (14). A clamping connector (18) constrains the head (14) to the seat (13) to prevent transversal translation and rotation to the head (14) and the seat (13). The pull connector (16) can be actuated alone and independently from the clamping connector (18) to make a provisional, pull-only connection between the head (14) and the coupling seat (13). The clamping connector (18) can be actuated independently from the pull connector (16) to allow postponing the complete clamping with respect to the provisional connection.
