摘要： A system (100) for attaching devices of subsea equipment to a line (10) comprising a line holding mechanism (11,110) and a line holding unit (404). The line holding unit (404) comprises a 5 longitudinal slit (403) for receiving the line (10), multiple gripping elements (13,130,230), and at least one resilient element (12,120,220), related to one subsea device. The resilient element(s) is/are configured to force the multiple gripping elements (13; 130,230) in a direction towards the line (10), whereby the line holding unit (404) is locked to the line (10) in a locking position. By the invention an improved latching device and an accompanying system for attaching and 10 detaching subsea equipment to and from a line is obtained.

The method is implemented by the system, comprising controlling installations of a plurality of ocean bottom submerged buoys and a plurality of four-component OBN seismic data acquisition instruments and sending positioning signals and timing signals to the plurality of ocean bottom submerged buoys through armored opto-electronic composite cables. The method also includes obtaining real-time and uninterrupted water temperature data, pressure data, density data, and salt saturation data along the armored opto-electronic composite cables from the ocean surface to locations of the plurality of ocean bottom submerged buoys, and calculating real-time and three-dimensional data of waters of a whole measurement work area through interpolation. The method further includes performing real-time correction on a hydroacoustic velocity of each hydroacoustic propagation trajectory based on the location, the hydroacoustic propagation trajectory and the three-dimensional data of each acquisition instrument.

摘要： A packed sensor line array system includes sensors mounted outboard of cable packs wrapped around a central mandrel. The system may have multiple rows (layers) of the sensors and cable packs, surrounded by a cannister. Cable retainers may be used to retain cable ends near sensors, to keep the cable ends out of the way of subsequent winding operations. The winding may be done in situ, with the mandrel mounted to a rotatable chuck that is rotated to wind the individual cable packs sequentially around the mandrel, with positioning of the sensors outboard of the windings occurring between the winding operations. A positionable indexing tool may be coupled to and moved along the mandrel, to define a space along the mandrel for each cable pack winding.
