<p>Arrangement for the deployment of seismic sensor units, such as sensor nodes (24), on the seabed, with a frame structure that is adapted to carry a container (11) for containment of a data registration unit and additional auxiliary equipment for the sensor node. The arrangement has supports (12, 13) that can rest against the seabed, and an attachment means (17) for a lifting hook, for raising and lowering by means of a crane. There is a holder (20) for the sensor node (24) that shall be positioned on the seabed and which is connected to the container through a signal cable (32). It comprises a releasable attachment means (22), which holds the sensor node (24) in a downwardly extending position with respect to the supports (12, 13). The attachment means (22) is located with a horizontal distance from the container (11). A latch mechanism (25) for the attachment means (22) is adapted to release the sensor node (24).</p> |
