METHOD AND MODULE FOR VESSEL CONTROL FOR RECORDING SEISMIC DATA AND FOR DETERMINING THE ROUTE OF THE VESSEL BY FORMATION OF THE FIRST STRAIGHT LINE FROM THE STARTING POINT TO THE END POINT AND FORMATION OF DISPLACED LINE

摘要

Method for acquiring seismic data by generating a first straight line (2) drawn from a starting point (3) to an end point (4), then generating a number of offset straight lines (6), each being placed perpendicular to the first straight line (2) and ending in a second point (7) in a distance X from the first straight line (2). The second points (7) provide an array of cross track offset values providing a survey line (10). A vessel steering module is described adapted to send command information to a vessel steering system. The invention also concerns use of the module for performing the method.
