Abstract: A fluid sampling and measuring assembly has: a sampling and measuring module configured to sample and analyse a fluid sample; a picking module configured to contain the fluid sample; at least one navigation module configured to navigate in the body of water; and at least one interface module configured to hydraulically connect a sampling station, the sampling and measuring module and the picking module. The sampling and measuring module and the picking module are configured to be mechanically and hydraulically coupled to each other and to the sampling station to take and analyse the fluid sample and the picking module is configured to be coupled to the navigation module to transfer the fluid sample to an analysis laboratory.

Abstract: 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.

Abstract: 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.

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: An underwater hydrocarbon processing facility has at least one fluid processing clusters provided with modules having, each, one fluid processing device and a plurality of first connection members configured to define the inlet and the outlet of the process fluids; and an interconnection unit having a plurality of second connection members defining inlet and outlet for the process fluids and configured to be operatively coupled to corresponding first connection members configured to operatively interconnect the modules.
