    Abstract: Container systems used in storage, deployment or retrieval of a seismic cable array comprise a container, at least two coiling elements attached to a bottom side of the container, and storage means for allocating or accommodating, in an ordered arrangement, a number of seismic stations and/or a number of couplers/splices and/or other discontinuities which are being interconnected by sections of the seismic cable. Said storage means is arranged between said coiling elements and are attached to the bottom side of the container. The seismic cable is spooled or wound around said coiling elements. Corresponding methods of storing a seismic cable and deploying/retrieving the seismic cable are based on the use of at least two coiling elements and storage means for allocating or accommodating a number of seismic stations and/or a number of couplers/splices and/or a number of other discontinuities and arranged between said coiling elements.

  • Patent number: 8840340
    Abstract: There is described an apparatus and method for deploying a sensor array comprising a plurality of sensors (5) joined together by connection cables (6) in one or more “chains”, and connected to an input/output device (8). An input/output connection unit (7, 15) is provided on a carrier (10), and the sensors are held on or in deployment devices (14a-14e) mounted to the carrier with their connection cables (6) connected to the input/output connection unit (7, 15). The input/output device (8) may also be mounted to the carrier, and connected to the connection unit (7, 15). The carrier (10), sensors, and input/output device (8) may be delivered as a single package to the area where the sensor array is to be deployed. The sensors are then moved from the carrier to their final positions. The deployment devices (14a-14e) may be detached from the carrier and moved sequentially to the sensor positions, and a sensor may be removed from the deployment device at each sensor position.
