PROBLEM TO BE SOLVED: To provide an underwater and water bottom cable line in which strain change involving with bending strain or repeated bending at a floating part can be reduced.SOLUTION: An underwater and water bottom cable line includes a plurality of cable cores including a conductor, an electric insulation layer provided on the outer periphery of the conductor, and a water shielding layer provided on the outer periphery of the electric insulation layer, and an integral mechanism for collecting at least a part of the plurality of cable cores in the longitudinal direction. A floating part being laid while floating the plurality of cable cores in the water is also provided, and at least one end of the floating part is connected with a floating facility. |
