An ice composite body (10) has an inner ice core (11) and a protective outer armour shell (12). The outer armour shell (12) consists of a base section (13), side sections (14) and a separate top section (15), which is free to move vertically between the side sections (14). The inner ice core (11) is
An ice composite body (10) has an inner ice core (11) and a protective outer armour shell (12). The outer armour shell (12) consists of a base section (13), side sections (14) and a separate top section (15), which is free to move vertically between the side sections (14). The inner ice core (11) is maintained in a frozen condition in use by refrigeration pipes (21), which are located at various levels therethrough. The inner ice core (11) is built up from thin layers of ice which are frozen one after the other. Following the freezing of each layer of ice the layer is rolled using a roller apparatus which provides a roller pressure in the range of 3.5 to 8 Newtons/mm2. The ice composite body (10) can be used in warm or cool waters for applications such as bridges, breakwaters, causeways, pontoons, artificial islands, dams, tidal barrages, wave power barrages, harbour walls, wind power farms or aircraft runways.

The method of claim 3, wherein said coiled structure has a cable support means formed integral therewith. 6. The method of claim 5, wherein said cable support means comprises a ring, trough or channel adapted in size to receive a cable structure. 7. The method of claim 3, wherein said coiled structure includes cable support means receiving means. 8. The method of claim 7, wherein a cable support means is mounted onto said carrier by means of said cable support means receiving means. 9. The method of claim 8, wherein said cable support means receiving means comprises a pair of flanges or notches in the wall of said carrier, and said cable support means comprises a generally U-shaped or circular cable structure receiving portion and two flanged portions, said flanged portions capable of being compressed and inserted between said pair of flanges or dimples of said carrier, locking said cable support means into position upon decompression of said flanged portions. 10. A method of installing a cable structure in an existing pipeline having an internal radius R' by the method of claim 1, said method comprising: discontinuously installing a plurality of carriers into an existing pipeline, said carriers optionally associated with a loading means which functions to exert pressure radially inward onto the exterior of the carrier between the carrier or a portion thereof and the interior wall of said pipeline, and fixing said carriers in said pipeline, wherein said carriers bear a cable support means adapted to receive a cable structure or are adapted to bear a cable support means; and where when said carriers bear no cable support means but are adapted to bear a cable support means, installing cable support means in a plurality of said carriers, said cable support means adapted to receive a cable structure, wherein said carrier comprises a hollow cylindrical sleeve or portion thereof, said cylindrical sleeve having a coiled or folded configuration whose largest dimension, prior to fixing in said pipeline and in a plane orthogonal and transverse to the direction of the length of the cylinder, is less than the diameter of the pipeline, said cylindrical sleeve being expandable by unfolding, uncoiling, or a combination thereof, to an external diameter R substantially the same as R', and when said carrier is of coiled metal having no loading means located between the external metal surface of the carrier and the interior of the pipeline wall, said metal carrier has an aspect ratio of at least 0.33; and routing a cable structure through said pipeline, said cable structure supported at intervals along the length thereof by said support means.
