[0002] The background art will be described with reference to FIG. 5 to FIG. For example, a marine hose line 1 as shown in Fig. 5 is used when crude oil is transported by sea from a single-point mooring buoy to a tanker. A specific configuration of the marine hose line 1 will be described.

[0003] The marine hose line 1 includes a plurality of marine hoses 3 (only three are shown). Each marine hose 3 includes a hose main body 5 that can be bent and deformed, and joints 7 that are respectively provided on the inner surfaces of both ends of the hose body 5. Each joint 7 has a nipple 9 fixed to the inner end surface of the hose body 5, and a mounting flange 1 provided at the tip of the nipple 9. Further, each mounting ink flange 11 is joined to each other by a mounting flange 11 of the mating marine hose 3 and a bolt and a nut.

[0004] A hose reel device 15 that winds the marine hose line 1 around the deck 13 of the tanker to collect the marine hose line 1 after the crude oil is transported by sea (see Figures 6 and 7) Is installed. A specific configuration of the hose reel device 15 will be described.

That is, the base 17 is provided on the deck 13 of the tanker. A rotating shaft 19 is rotatably provided on the base 17 via a bearing (not shown). The rotating shaft 19 is integrated with the drum 21. That is, the drum 21 is rotatably provided on the base 17 via the rotary shaft 19 and the bearing.

The drum 21 includes a pair of circular rotating disks 23 (only one is shown) and a plurality of rods 25. The pair of turntables 23 are integrated with the rotary shaft 19 and face each other. The The plurality of rods 25 couples a pair of turntables 23. Here, the cylindrical support surface 27 (that is, the cylindrical virtual support surface) that supports the hose body 5 is formed on the outer peripheral surface of the force drum 21 by the plurality of rods 25.

A hydraulic motor (actuator) 29 that rotates the drum 21 in the winding direction integrally with the rotary shaft 19 is provided in the vicinity of the base 17. An output shaft (not shown) of the hydraulic motor 29 is connected to the rotary shaft 19 via a gear mechanism (not shown).

[0014] In the marine hose line, a connection flexible tube is provided between a pair of adjacent marine hoses, and each connection flexible tube includes a flexible tube main body. When winding the hose line, or when kinking occurs in the marine hose line at sea or in the sea, the flexible tube body squeezes appropriately. As a result, the local increase in bending near the portion of the hose body that overlaps the joint is suppressed.

Here, it is preferable that at least a part of the flexible tube main body is a bellows tube. Further, it is preferable that a reinforcing ring is embedded in the flexible tube main body. Furthermore, it is preferable that the connection flexible tube includes an outer skin layer in which the reinforcing ring is embedded and a seal layer formed on the inner surface of the outer skin layer.
