    摘要： The invention relates to a method for draining a fluid-transporting underwater pipe (2) which is submerged and filled with water, comprising pumping of at least a portion of the water present inside the submerged pipe by a submersible pumping unit (6) connected at a point on the pipe, the volume of pumped water inside the pipe being compensated by a gas injected under pressure into the submerged pipe at a point (18) on the pipe located higher than the connection point (12; 14) to the submersible pumping unit. The invention also relates to a facility for implementing such a method.

    摘要： The present invention relates to a seafloor-surface linking apparatus between a single floating support (2) and the seafloor, comprising a plurality of flexible lines comprising flexible hoses (1) stretching from said floating support to the seafloor, said flexible lines being supported by a plurality of tubes (3, 3a-3b), each tube defining two portions of hose comprising a first portion of flexible line (1-1) embodied as a double catenary curve descending from the floating support (2) to said tube and a second portion of flexible line (1-2) embodied as a simple catenary curve between said tube and the point of contact (l-2a, l-2b) of the flexible hose on the seafloor. The apparatus comprises at least one support structure (4) comprising a lower element forming a base (4-1) resting and/or anchored or driven into the seafloor and an upper element (4-2, 4-2a - 4-2b) supporting at least two tubes, lower (3b) and upper (3a), arranged at differing heights (Ha, Hb) such that the low point (1-1b) of the first portion (1-1) of flexible line passing through the lower tube (1b) is located below the low point (1-la) of the first portion (1-1) of flexible line passing through the upper tube (3a).

    摘要： The present invention relates to a modular device for the liquid/liquid gravity separation of the aqueous phases (11-1) and oil phase (10-1) of crude oil at the seabed (30), including a plurality of separation modules (1a) connected to a common collecting device (1b). Each separation module (1a) includes a fluid flow line (6) connected to at least one gravity separation pipe (7) by a tubular device (8) having an elbow. The common collecting device (1b) includes a first tank (3) to which crude oil is supplied by a supply pipe resting on the seabed (5) via a first inlet (3-1) thereof, a plurality of first outlets (3a) supplying crude oil to said flow lines (6). Two aqueous and oil phases are separated within separation pipes (7) before being discharged into a second tank (4) via second inlets (4a) of said second tank to which the separation pipes (7) are connected. The oil phase (10-1) is conveyed to the surface from the second tank (4) via a first discharge pipe (10). The aqueous phase (11-1) is conveyed to the seabed.
