Method and vessel steering module for seismic data acquiring and for routing a vessel, by generating a first straight line from a starting point to an end point and generating offset straight lines

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.
