METHOD AND DEVICE FOR STEERING A SEISMIC VESSEL, ON THE BASIS OF BOUNDARIES OF BINNING COVERAGE ZONES.

摘要

It is proposed a method for steering a seismic vessel (6) associated with a sail line (30), comprising: a) computing distances d i , i {1 ... n }, from n reflexion points (1) to a boundary (31) of a binning coverage zone associated with a previous preplot line; b) computing a distance D, from said n reflexion points to n target reflexion points (1'), as a function of said distances d i ; and c) providing steering information comprising or based on the distance D to a navigation system or to an operator of a navigation system, to alter the course of the seismic vessel.
