Abstract

A method for managing the speed of at least one first vessel in a seismic survey. The first vessel sails at a current speed and performing a series of shots according to a predefined set of shot points, called preplot. The method includes, during at least a part of said seismic survey, computing an updated speed for the first vessel, using at least a time prediction shift defined as a time difference between at least: a raw time prediction for the first vessel, the raw time prediction being defined by the time to reach a shot point based on the current speed of the first vessel, and a corrected time prediction, for the first vessel, depending on at least one parameter related to at least one vessel of the seismic survey. Any of the raw predictions being computed for a given shot point in the preplot and at least one of the time prediction shift are computed for a given shot point in the preplot.
