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 marine source element is configured to generate seismic waves. The source element includes a body and a source actuator attached to the body and configured to generate the seismic waves. The body is autonomous from a vessel towing streamers along a pre-plot line associated with a seismic survey.

Abstract: A cable-protecting device is used on a cable of a marine survey system to oppose cable bending and/or to limit a bending radius of the cable. The cable-protecting device has a functional body made of at least two portions configured to be clamped together to surround the cable, a gripping system configured to oppose the functional body sliding along the cable, and a closing system configured enable the at least two portions to engage fast and remain clamped.

Abstract: A source element for generating seismic waves includes a housing; a partitioning element placed inside the housing and configured to split the housing in a closed chamber and an opened chamber; and a valve in fluid communication with the closed chamber and configured to supply high-pressure air to the closed chamber to make the partitioning element oscillates. An oscillation of the partitioning element generates low-frequency seismic waves.
