Ocean floating installations (1) are disposed on the ocean. The ocean floating installations (1) float on the ocean with the lower part of the ocean floating installations (1) being fixed to the seabed by mooring ropes (11). Each of the ocean floating installations (1) is connected at a connection part (5a) to a cable (3), which is a first cable. Each of the cables (3) is connected at a connection part (5b) to a cable (7), which is a second cable. In other words, the ocean floating installations (1) are connected to each other by the cables (3) and the cable (7). A connection is established with the cables (7) at the connection parts (5b) located on the seabed. In other words, the cables (7) are installed on the seabed.
An undersea cable comprising:
An undersea cable installation structure that is installed undersea comprising:
A method for installing an undersea cable including a first cable which has an impermeable layer formed by winding a tape-shaped component and a second cable having an impermeable layer formed of a lead sheath, wherein each of the first cable and the second cable comprises at least a power cable and armoring portions in which the power cable includes a conductor on which an insulating layer, a shielding layer, the impermeable layer, and an anti-corrosive layer are formed in sequence and the armoring portions are formed by disposing a plurality of wire material on the periphery side of the whole of a plurality of the power cables in the circumferential direction of the periphery of the whole power cables and providing the wire materials helically in the axial direction of the power cables, the method comprising:
A method for installing an undersea cable including a pair of first cables each of which has an impermeable layer formed by winding a tape-shaped component and a second cable which has an impermeable layer formed of a lead sheath, wherein each of the first cable and the second cable comprises at least a power cable and armoring portions in which the power cable includes a conductor on which an insulating layer, a shielding layer, the impermeable layer, and an anti-corrosive layer are formed in sequence and the armoring portions are formed by disposing a plurality of wire material on the periphery side of the whole of a plurality of the power cables in the circumferential direction of the periphery of the whole power cables and providing the wire materials helically in the axial direction of the power cables, the method comprising:
