One describes a flexible duct for transporting fluids (40) comprising a main flexible pipe (1), at least one fixing and anchoring pipe (2, 2', 2'') associated on the outside and parallel to the main pipe (1) and at least one ballast (5, 27, 37) associated to at least one fixing and anchoring pipe (2, 2', 2''), the main pipe (1) is capable of being used submerged in an aqueous medium so as to comprise a relative pressure between the internal pressure of the main pipe (1) and a substantially null external pressure from the aqueous medium, and further is capable of being subjected to a compensation of loss of charge. One further describes the use of a flexible duct for transporting fluids (40) as defined in claims 1-15, the flexible duct (40) comprising a main pipe (1) arranged submerged in an aqueous medium so as to comprise a relative pressure between the internal pressure of the main pipe (1) and a substantially null external pressure from the aqueous medium, and further being subjected to a compensation of loss of charge.
