Storage and installation systems used in storage, deployment or retrieval of a seismic cable array include one or more baskets adapted for being stacked. Each basket is dimensioned to allocate, in an ordered arrangement, a number of seismic stations interconnected by sections of seismic cable. Corresponding methods of storing a seismic cable and deploying/retrieving a seismic cable are based on the use of baskets having an ordered arrangement of seismic stations.

The invention claimed is: 1. A seismic cable storage and installation system for use in storage, deployment or retrieval of a seismic cable array, comprising: one or more baskets adapted for being stacked, wherein each basket is dimensioned to allocate, in an ordered arrangement, a number of seismic stations interconnected by sections of seismic cable; and wherein the seismic stations are arranged in prepositioned locations, the prepositioned locations defining the orientation of the seismic stations using arrangement details. 2. The storage and installation system according to claim 1, wherein the ordered arrangement is a single layer arrangement of the seismic stations within each basket. 3. The storage and installation system according to claim 1, wherein the seismic stations have a substantially non-circular cross section in a direction perpendicular to the cable direction. 4. The storage and installation system according to claim 1, wherein the seismic stations have a substantially circular cross section perpendicular to the cable direction. 5. The storage and installation device according to claim 1, wherein the arrangement details comprise a basket center volume defined by a cylindrical center element of each basket. 6. The storage and installation device according to claim 1, wherein the arrangement details comprise slits within a peripheral wall of the one or more baskets for defining the positions of and for holding the seismic stations in the prepositioned locations in relation to said peripheral wall. 7. The storage and installation device according to claim 1, wherein the arrangement details comprise a number of elongated stands that are, in normal use, arranged in a substantially parallel, vertically upright fashion, the stands being adapted to hold the seismic stations in the prepositioned locations with defined orientations. 8. The storage and installation device according to claim 7, wherein the arrangement details comprise radial bars which define the prepositioned locations for allocating one or more of the seismic stations. 9. The storage and installation device according to claim 8, wherein each radial bar is hingedly attached to a respective one of the stands in order that, when the radial bars do not accommodate the seismic stations, the radial bars can be pivoted towards the stands to which they are attached. 10. The storage and installation device according to claim 8, wherein one of the stands has a recess designed so that a corresponding one of the radial bars may slide into said recess after being pivoted. 11. A method of deploying/retrieving a seismic cable array at a subsea location, comprising: arranging a storage and installation device on a vessel, wherein the device includes one or more baskets adapted for being stacked, each basket dimensioned to allocate, in an ordered arrangement, a number of seismic stations interconnected by sections of seismic cable; arranging the seismic stations in prepositioned locations, the prepositioned locations defining the orientation of the seismic stations using arrangement details; and deploying/retrieving the cable including the seismic stations from/into said storage and installation device on said vessel. 12. The method according to claim 11, wherein each basket includes the arrangement details in the form of slits within a peripheral wall of the one or more baskets for defining the positions of and for holding the seismic stations in the prepositioned locations in relation to said peripheral wall. 13. A method of storing a seismic cable, comprising: providing a seismic cable array which includes a number of seismic stations; and arranging said array in a storage and installation device, wherein the device includes one or more baskets adapted for being stacked, each basket dimensioned to allocate, in an ordered arrangement, the seismic stations interconnected by sections of cable; and arranging the seismic stations in prepositioned locations, the prepositioned locations defining the orientation of the seismic stations using arrangement details. 14. The method according to claim 13, wherein said array is arranged with the seismic stations in a single layer arrangement. 15. The method according to claim 13, wherein each basket includes the arrangement details in the form of slits within a peripheral wall of the one or more baskets for defining the positions of and for holding the seismic stations in the prepositioned locations in relation to said peripheral wall.
