Abstract: Seismic source modules are combined into seismic source strings that are grouped into seismic source arrays. The seismic source array includes a plurality of seismic source strings arranged in parallel and towed behind a seismic source vessel. Each seismic source string includes a plurality of seismic source modules coupled in series along the seismic source string. Each seismic source module includes a protective cage, at least one seismic source disposed within the protective cage and decoupled from the protective cage and a pair of couplers in communication with the protective cage. The seismic source string also includes a plurality of tethers attached to couplers between adjacent pairs of seismic source modules in the series of seismic source modules.

Abstract: A passive, automatic cable winding system is coupled by a cable to a seismic source or streamer and automatically adjusts a payout of the cable connecting the seismic source or streamer to a float. The passive, automatic cable winding system includes a tensioning system configured so that when the seismic source or streamer is deployed during a seismic survey the water exerts force on the seismic source or streamer and the passive, automatic cable winding system pays out the cable so that the seismic source or streamer is at the desired depth for the seismic survey. When the seismic source or streamer is pulled out of the water during recovery, the passive, automatic winding system reduces the length of the cable between the float and the seismic source or streamer, and thus reduces the chances of the cable becoming tangled during recovery.

Abstract: A depth-varying marine acoustic source array is configured for generating an acoustic wave in a body of water. The depth-varying marine acoustic source array includes a float; plural source points connected to the float through corresponding cables; and a housing extending from a first source point to a last source point, the housing including plural segments. The at least one segment is configured to withstand bending.
