Abstract: Method and seismic data acquisition system includes a streamer spread including (i) a streamer having receivers for recording seismic data and (ii) a connecting cable connecting the streamer to a towing vessel; a collar device configured to move along the connecting cable, between the towing vessel and the streamer; and a remotely operated vehicle (ROV) attached to the collar device with an umbilical and configured to carry an interchangeable payload.

Abstract: A survey plan is designed and potentially adjusted so that seismic data acquired during the survey include inline and cross-line seismic data irregularities suitable for compressive sensing reconstruction. At least one of the inline and cross-line irregularities is dynamic and may be due to source, vessel(s) and/or streamer steering.

Abstract: A diving fairing to be used with a front-end rigging in a seismic survey system, the diving fairing including a body extending along a longitudinal axis X; a first through passage formed along a transversal axis Y, which is perpendicular on the longitudinal axis X; and a second through passage formed along the transversal axis Y, offset from the first through passage.

Abstract: A diving fairing to be attached to a line of a seismic survey system, the diving fairing including a body extending along a longitudinal axis X and having a passage formed along a transversal axis Y, which is perpendicular on the longitudinal axis X; and a first weight located on the body. The body is symmetrical relative to the longitudinal axis X and the first weight is distributed along the body asymmetrically to exert a torque relative to the passage that creates a non-zero angle of attack of the body with a horizontal direction.

Abstract: A method for steering a marine seismic acquisition system by determining a steering point associated with towed seismic equipment is described. Coverage boundaries for a current line in a seismic survey and for an already acquired adjacent line in the seismic survey are computed. Cross-line distances between the coverage boundary for the current line and the coverage boundary for the adjacent line are computed based on a set of specifications for the seismic survey. A steering point associated with towed seismic equipment is determined based on the computed cross-line distances. A least one steering command for a steering element in the marine seismic acquisition system is generated based on the determined steering point.
