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.

Underwater hydrocarbon processing facility

A self-propelled underwater vehicle for underground laying a continuous elongated member in a bed of a body of water having a work assembly, which is configured to be set, at least partly, into the bed, and is provided with two facing supporting walls for delimiting a space there-between and supporting two opposite scarp slopes; and drive assemblies, which are arranged on opposite sides of the work assembly and are configured to rest on the bed and advancing the work assembly in a travelling direction.

Self-propelled underwater vehicles and systems for underground laying a continuous elongated member in a bed of a body of water

A method of joining two portions of an underwater pipeline for conducting fluid and/or gas on the bed of a body of water, the method including the steps of: joining a telescopic sleeve, having a first coupling head, to a first end of a first pipeline portion above the body of water; positioning the first end, the telescopic sleeve, and the first coupling head in a first given position on the bed of the body of water; joining a second coupling head to a second end of a second pipeline portion above the body of water; positioning the second end and the second coupling head in a second given position, close to the first coupling head, below the body of water; and connecting the first and second coupling head hermetically below the body of water.

Method of joining two portions of an underwater pipeline for conducting fluids and/or gas

A method of joining two portions of an underwater pipeline laid on the bed of a body of water to conduct fluid and/or gas, the method including: joining a telescopic sleeve, having a first coupling head, to a first end of a first pipeline portion above the body of water; laying the first end, the telescopic sleeve, and the first coupling head on the bed of the body of water; joining a second coupling head to a second end of a second pipeline portion above the body of water; laying the second end and the second coupling head on the bed of the body of water, close to the first coupling head; roughly aligning the first and second coupling head in the body of water; and clamping the first and second coupling head to each other in the body of water.

A method of temporarily supporting a soil mass susceptible to slide at a scarp slope bounding the soil mass includes advancing a supporting wall in an advancing direction along the scarp slope; and, in addition to the movement in the advancing direction, also moving a surface portion, in direct contact with the soil mass, of the supporting wall, so as to minimize friction between the soil mass and the supporting wall.

Method and system for temporarily supporting a soil mass susceptible to slide

A method of laying underwater pipelines in the bed of a body of water, the method including laying an underwater pipeline along a given path on the bed of the body of water; breaking up a ground mass along the path to a given depth in the bed; and fluidifying the broken ground mass beneath the underwater pipeline to sink the underwater pipeline into the fluidified ground mass.

Method and system of laying underwater pipelines in the bed of a body of water

A method of underground laying a continuous elongated member in a bed of a body of water, wherein the continuous elongated member lies on the bed of the body of water along a given path; the method including the steps of:
