The invention relates to a flexible cryogenic transfer hose (7) for connecting two cryogenic facilities (2,8), the hose (7) in use extending in a maritime environment and having a length of at least 30 m, preferably at least 100m, comprising:
- an inner hose (10) with at least two segments (12,13), the inner hose segments (12,13) being interconnected via two inner connecting members (16,17), with a diameter larger than an outer diameter of the inner hose (10), the inner hose (10) being flexible and comprising a flexible reinforced wall, the inner hose (10) having an internal diameter of at least 20 cm,
- an outer hose (11) surrounding the inner hose (10) comprising a watertight reinforced elastomeric material, the outer hose (11) comprising at least two segments (20,21), the outer hose segments (20,21) being interconnected via two outer connecting members (24,25), the outer hose (11) having a wall thickness of at least 3 cm and a bend radius of at least 3 m, and an internal diameter of at least 25 cm,
the inner hose (10) being kept at a distance from the outer hose (11) via a number of spacer elements (28,29) bridging the distance h i between an outer wall of the inner hose (10) and an inner wall of the outer hose (11), which distance is between 0.1 and 0.8 times the internal diameter d i of the inner hose (10), wherein a longitudinal position of a pair of connecting members (16,17) of the inner hose (10) is situated at or near a longitudinal position of a pair of connecting members (24,25) of the outer hose (11). |
