Abstract
A method and control device for controlling the position of a marine seismic streamer spread and the ability for controlling individual marine seismic streamers both in shape and position relative to other marine seismic streamers and thereby counter effects from crosscurrent or other dynamic forces in a towed spread behind a seismic survey vessel. The system includes sensor means for determining information to control the streamer and a control device, including a housingmechanically and at least partly electrically connected in series between two adjacent sections of the streamer, at least three control membersprojecting from the housing, and control means adjusting the respective angular positions of the control membersso as to control the lateral and vertical position of the streamer. The rotational position of the streamerand control deviceis measured, and the measured rotational position is used to control the angular position of the control members, and thus the lateral and vertical displacement of the streamer
