A composite hose for transfer of cryogenic fluids, includes two end flanges, a helical wound inner wire several layers of protective fabric layers, at least one gas-tight sealing layer sandwiched between one or more protective layers and an outer helical wound wire which is placed on top of the protective layers between the pitch of the inner wire, characterized in that the inner wire is connected to a flexible inner liner that follow any axial and/or radial displacement of the inner wire and that covers the inner corrugations of the composite hose so to create a smooth inner bore of the composite hose.

1. A hose assembly for transfer of cryogenic fluids comprising: an inner composite hose for transferring cryogenic fluids, the inner composite hose being comprised of two inner hose segments, a sealing area located between the two inner hose segments, sealing layers, a space between the sealing layers, and end fittings;an outer protective hose or sleeve arranged around the inner composite hose in a concentric manner, the outer protective hose comprising at least one of an elastomeric material and a plastic material;an annular gap between the inner and outer hoses;one or more spacer members bridging the annular gap;an insulation layer in the annular gap; anda pressure relief system that reliefs an excess of pressure resulting from warming up of a cryogenic transfer system after an offload,the pressure relief system comprising i) a pressure relief tube, and ii) a pressure relief and check valve located along the pressure relief tube and situated in the annular gap or integrated in one of the end fittings of the inner hose,wherein the pressure relief tube connects, i) the space between sealing layers of the inner hose or the sealing area of the two inner hose segments, respectively to ii) the annular space or a flow path of the inner hose, via the pressure relief or check valve, respectively. 2. The hose assembly for transfer of cryogenic fluids according to claim 1, wherein the pressure relief tube connects the space between sealing layers of the inner hose to the annular space, via the pressure relief and check valve, thereby leading excess of pressure from the space between sealing layers of the inner hose into the annular gap. 3. The hose assembly for transfer of cryogenic fluids according to claim 2, wherein the one or more spacer members bridging the annular gap between the inner and outer hoses are placed on top of the insulation layer such that the insulation layer is kept continuous on the whole hose segment length. 4. The hose assembly for transfer of cryogenic fluids according to claim 2, wherein the one or more spacer members bridging the annular gap between the inner and outer hoses incorporate static insulation material within said one or more spacer members. 5. The hose assembly for transfer of cryogenic fluids according to claim 1, wherein the pressure relief tube connects the sealing area of the two inner hose segments to the the flow path of the inner hose, via the pressure relief and check valve, thereby leading excess of pressure from the sealing area into the flow path of the inner hose. 6. The hose assembly for transfer of cryogenic fluids according to claim 5, wherein the one or more spacer members bridging the annular gap between the inner and outer hoses are placed on top of the insulation layer such that the insulation layer is kept continuous on the whole hose segment length. 7. The hose assembly for transfer of cryogenic fluids according to claim 5, wherein the one or more spacer members bridging the annular gap between the inner and outer hoses incorporate static insulation material within said one or more spacer members. 8. The hose assembly for transfer of cryogenic fluids according to claim 1, wherein the one or more spacer members bridging the annular gap between the inner and outer hoses are placed on top of the insulation layer such that the insulation layer is kept continuous on the whole hose segment length. 9. The hose assembly for transfer of cryogenic fluids according to claim 1, wherein the one or more spacer members bridging the annular gap between the inner and outer hoses incorporate static insulation material within said one or more spacer members. 10. A hose assembly for transfer of cryogenic fluids comprising: an inner composite hose, for transferring cryogenic fluids, comprised of two inner hose segments, a sealing area located between the two inner hose segments, sealing layers, a space between the sealing layers, and end fittings;an outer protective hose concentrically arranged around the inner composite hose, the outer protective hose comprising at least one of an elastomeric material and a plastic material;an annular gap between the inner and outer hoses;a spacer member bridging the annular gap; anda pressure relief system that reliefs an excess of pressure,the pressure relief system comprising i) a pressure relief tube, and ii) a pressure relief valve located along the pressure relief tube,wherein the pressure relief tube connects the space between sealing layers of the inner hose to the annular space, via the pressure relief valve, thereby leading excess of pressure from the space between sealing layers of the inner hose into the annular gap. 11. A hose assembly for transfer of cryogenic fluids comprising: an inner composite hose, for transferring cryogenic fluids, comprised of two inner hose segments, a sealing area located between the two inner hose segments, sealing layers, a space between the sealing layers, and end fittings;an outer protective hose concentrically arranged around the inner composite hose, the outer protective hose comprising at least one of an elastomeric material and a plastic material;an annular gap between the inner and outer hoses;a spacer member bridging the annular gap; anda pressure relief system that reliefs an excess of pressure,the pressure relief system comprising i) a pressure relief tube, and ii) a pressure relief valve located along the pressure relief tube,the pressure relief tube connects the sealing area of the two inner hose segments to the the flow path of the inner hose, via the pressure relief valve, thereby leading excess of pressure from the sealing area into the flow path of the inner hose.
