Abstract: An arrangement for a hose system (11) having an inner main hose (12) and an outer cover hose (13) delimiting a ring shaped air filled volume (14) to make the hose buoyant in water. At least at one end there is a connector (15) attached to the main hose as well as the cover hose, and which at its free end is attached to, or integrated with, a connector part (16) for connection of the hose system (11) to an external system. The connector (15) includes an inner sleeve (22), to which the end of the main hose (12) is attached to, as the inner sleeve (22) by its free end (26) is equipped with an element, in particular threads, for connection to a pipe system, an outer sleeve (16) to which the end of the cover hose is attached, a connector element (30) for connecting the inner sleeve (22) detachably to the outer sleeve (16), and a connection between the two hose parts (12, 14) having a one way valve which allows draining of the outer hose (14) to the main hose (12).

Abstract: Hose system for use in an hydraulic system, includes a working hose for the transfer of hydraulic fluid having a pressure substantially higher than atmospheric pressure, and a safety hose surrounding the working hose, the working hose and the safety hose being tightly joined. A pressure transmitter is arranged for indicating a rise in pressure in a space between the two hoses. The system includes at least one bushing for releasable connection to the working hose and the safety hose. The cross-section of the safety hose allows space for the passing of the end couplings of the working hose. The bushing includes a space communicating with the space between the working hose and the safety hose, the space being in communication with a pressure transmitter able to signal an increase in pressure in the space between the working hose and the safety hose.

Abstract: Device for a hose structure (11) with an inner main hose (12) and an outer cover hose (13) which delimits a pipe-shaped air filled space (14) intended to give the hose uplift in water. At one end there is a coupling element (15) which forms a fastening for the main hose and cover hose and which at its free end is connected to or integrated with a coupling part (16) for connection of the hose structure (11) to an outer connection. The coupling element (15) comprises an inner sleeve in which the end (18) of the main hose (12) is inserted into and fixed to. An internal sleeve (22) is associated with the coupling part (16), as the inner sleeve (17) has outside threads (20). It comprises an outer sleeve (24) with the end of the cover hose clamped to it and with inside threads for screwing onto the inner sleeve (17).
