Patent ID: 8483008

Claim:
A computer-implemented method, comprising: monitoring a plurality of actual positions of a plurality of steerable positioning elements in a towed-array of a marine seismic survey spread while the marine seismic survey spread sails along a generally advancing curved sail line, wherein the sail line has a radius that is a function of a width of the marine seismic survey spread and the sail line is a function of a roll in a y-direction (“DY”) and a roll in an x-direction (“DX”); determining respective desired positions of the steerable positioning elements; determining a plurality of steering residuals between the actual positions and the respective desired positions of the steerable positioning elements; issuing steering commands to the steerable positioning elements as indicated by the determined steering residuals to steer the steerable positioning elements to the respective desired positions; and acquiring full azimuth seismic data using the marine seismic survey spread.
