Hose

By designing a composite hose, utilizing the tubular voids of the inner main hose and the outer sheath hose to provide buoyancy, and setting joint elements at the ends to monitor leakage, the problems of insufficient buoyancy and safety of existing floating hoses are solved, achieving for more efficient leak handling and economical replacement.

Embodiment Construction

[0014] attached figure 1 The end of a composite or "composite" hose 11 formed in accordance with the present invention is shown. The main element is the internal main hose 12 which can be designed to carry bunker fuel, sludge or other pumpable fluids between two units separated by water, which requires placing said hose above the water .

[0015] The main hose 12 is surrounded by a jacket hose 13 which may have a diameter creating a tubular interspace 14 between the two hoses. The void 14 will be filled with air in order to reduce the weight of the composite hose so that the hose can float on the water. However, the cavities can also be filled with other gases or partially or completely filled with foam. In an alternative embodiment, in order to maintain the distance between the main hose 12 and the sheath hose 13 , a spacer, eg a tubular corrugated profile, may be arranged in the interspace 14 .

[0016] A joint element 15 is arranged at each end or at either connection f...

Abstract

Arrangement for a hose system (11) comprising an inner main hose (12) and an outer cover hose (13) delimiting a ring shaped air filled volume (14) designed to make the hose bouyant 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, connector part (16) for connection of the hose system (11) to an external system. The connector (15) comprises:—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) with 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) comprising a one way valve which allows draining the outer hose (14) to the main hose (12).

Description

technical field [0001] The invention relates to a hose. Background technique [0002] Hoses capable of buoyant water are used for the transfer of pumpable fluids offshore, such as refueling a platform from a supply vessel, or transferring sludge from a platform to a supply vessel. For this purpose, it is known to attach a flotation device to an ordinary hose, or to attach a tubular sleeve of foamed material to said hose. Both hose configurations described above provide buoyancy but no added safety. Furthermore, there is no suitable way to provide a hose that is resistant to abrasion. [0003] With growing concerns over contamination issues due to spills, safety measures that continue to scale with hose sizes are required. [0004] Hoses have been proposed where the outer hose accommodates leaks from the inner main hose. This type of safety hose has been able to be manufactured as a hose that floats on water. But the primary goal of establishing safety has hindered the d...
